Yes, I'm late to the party, But a modern race quad will destroy ANY car up to a hundred miles an hour. I've driven an Ariel Atom V8 on track, and it is SAVAGE....But at the end of the day, power to weight wins.
I just became aware of the relationship between the hypetrain race quads' propellers disc radius, disc radius of an electric saw blade, and fidget spinner toy disc radius - Thank you so very much. Outstanding Video - You may not realize it but you helped to save my life.
Ok, so I know this is a pretty old video, but there is something you guys got wrong in this video around the 10:00 point when you talked about hang time. You're right that if you're throttled up and pointed downwards, more thrust equals less hang time, but whenever you're throttled down then the speed you fall at is dependent on the prop shape. The air will start to spin the props instead of the motors, assuming you're throttled down. This is what helicopter pilots call autorotating. If you have a high disk space, then more air is hitting your prop as you fall, and more energy is dissipating into rotating the propeller, making your prop act kind of like a parachute. So a higher blade number or a lower pitch will give you more hang time, because it gives a higher disk space. Btw, I absolutely love you guys, I don't mean to insult you or anything, I just know this is something a lot of people forget about. I also know you guys have more experience flying quads than I probably ever will, so I'm perfectly happy to accept that I'm completely wrong if somebody explains it to me. Thank you guys for making these awesome videos and helping people learn and get interested in this hobby, you do a great job, keep it up!
I missed the last run of 5" penta props for my quad. I did however snag up about 20 sets of quadra props. Not only have I noticed a longer run time (battery wise) and without even going into hang time, just lift from an additional blade(s) is very interesting. The motors seem to fair well and may wear out quicker in the long run, but in a yearning and learning sense of aerotecture, I'm on the same page. I like hearing things & thoughts of any age. Communicating my 2¢ or maybe $ of experience and knowledge to the communal forum and walking away a wiser individual or as a enlightened community is always a good feeling at the end of the day. If you want more hang time, fly right side up at low throttle with a high blade count prop. Hang time doesn't necessarily have to be calculated as inverted orientation. The key term difference is lift as opposed to thrust.
+ThatHPI GUY Magic smoke be dammed! In the name of science, full speed! Also, film it, cause everyone likes to see someone else blow up their toys on youtube.
Great info . Thanks Chad and Steele. I flew a gimp-fan tri a while back.... you could hear the blades flexing when you pumped it into a 180° corner and jammed the throttle on to get moving forwards again. I took them off straight away. DAL props all the way for me. 6x4.5 on my robocat with 2206 1900kv... heavier quad and 5x4.5x3 on my qav210 with rs2205 2300kv pocket rocket. Cheers guys!
Brilliant run through guys thanks. Trying to encompass the theory of propeller efficiency in 15mins takes some doing. The helicopter designers have all been through this process. If you equate the type of flying you want to do with a helicopter you will find that machine has the appropriate rotor design already. I.e. Fast, nimble machine, look at a MD500e with 5 short blades. Pro's = Small, high loading disc area, but really biting hard, using those 5 blades to max effect for rapid/agile response. Cons = High fuel consumption/reduced endurance. Slow, cruiser machine, look at Bell jetranger with 2 longer blades. Pro's = Very efficient, larger disc area with lower loading. Low fuel consumption/increased endurance. Cons = Reduced responsiveness, require more clearance from fuselage. The key difference with multirotor blades is their requirement to accelerate and decelerate rapidly to generate the torque for Yaw as well as the asymmetric lift for Roll (all at the same bewildering time!!) The glaring next step would be variable pitch blades which would transform performance. That would be like going from riding a bike with one fixed 3rd gear to a 10 speed racer. fast at accelerating (fine pitch) to high speed blitzer (coarse pitch). BIG problem with that is added complexity and much MUCH more expensive replacement costs when you hit that tree or race pylon etc!! Please do more of these talk through's and you guys should link to your store and sell these blades so we can support your Rotor Riot posts.
Excellent analysis and comparison to car physics. The knowledgeable insights and personal experiences supporting quad dynamics is unrivaled in TH-cam. Great episode Team RR!
Finally! Everything (almost anyways) in one place! This is the type of video that helps promote interest in our hobby from noobs to ace pilots alike. Well done RR.
Thanks guys, I've recently changed my HQ 5045bn for 5040 3 blades and I won't go back now! Love these props, really enough speed for me and great response, and a real advantage I discovered is that even if you broke a blade with touching a branch you can still fly and go home and don't have to walk and search the quad....ok....the noise is terrible but the quad still fly.... ;-)
great vid guys. I went back to a 5x4 from a 5x4.5 and dumped the bull nose all together. flight time is way better now. and both quads handle great. Thanks
Thanks for answering every question (and then some!) I've had about props in 15 minutes. I can now stop sifting through pages upon pages of forum posts and use this as my prop bible. Cheers.
Best video on props so far, to the point and very easy to understand. Been thinking about trying some tri's and bullnoose, so this really pointed me in the right direction!
Thanks guys, I am just about to start tuning my quad for the first time and your video is a big help. May have to watch it several more times to under stand more about tuning. Cheers
Awesome video! It may have been worth while mentioning prop balancing though! It reduces vibrations, and increases efficiency - RPM for those of you curious!
Very good video on props. I'm just getting started after flying a Hubsan X4 and a Phantom 4 for a few months, and I really didn't understand the differences between prop sizes, blade count and pitch. Subscribed! I just started flying a Storm SRD250 with 6" props and while I'm still learning how to control it at high speeds, I can really tell that it's a great quad. Hopefully soon, I'll be able to really get the most out of it. Great channel, guys!
Hi guys, interesting episode. One question: Regarding recommending 6" props as being better suited for flying in wind at 14:00, I was under the impression that for a given weight 'copter a smaller diameter prop, with it's increased disc loading, would be less upset by the wind. Thoughts?
One crucial thing you guys didn't mention was prop brands...lol, you only talked about HQ props, (except for steele talking about the GemFans), why no mention of DAL "indestructible" props? or carbon fiber props? I myself use HQ 5x4x3 and 5x4x4 as well as DAL indestructible 5x4x3 (for their price/ durability compared to HQs) You should've mentioned this stuff. And why no links to any of these props in the description? Newbies will have no idea what props you guys are talking about, and where the best place to buy them is.
+Anthony Anastasio Because the point of the video is to explain properties of props and how they affect performance. You can easily get that information from forums. When this video is still around in 5 years, will the brands remain the same? Unlikely.
+TT Q Yeah, but the people watching this channel are watching this channel because they want to hear that "forum" information from the professionals so they know it is accurate and that it is what the professionals use.
great descriptions for the different types and handling and uses. technical stuff and bench tests work, but real world applications are good to know too. Thanks!
Just want to say thank you for doing these vids. They really helps with my knowledge base and educates me on the different aspects and science behind what each piece does. Also through the videos I have learned what I'm doing wrong like 5 DAL bull nose blades with a Glacier 45C 1300mAh 3S 11.1V LiPo Battery which is too small from what I understand from the video. so time for some different props.
Great video!! Very helpful, you are doing a great job. Btw from my personal experience, harder the props more damage to the motor durring a crash. I used sone Gemfan 50x46x2 BN and bent one of my motor shaft...
Sweet vid, makes it simple. Would like to see you guys discuss your FPV setups some time - What cams & VTxs you use, how many MW, which antennas you use & why.
what frame, prop size, motors, etc. would you recommend to carry 2 gopros and still be nimble enough to do flips, come out of deep dives, turn really tight corners, etc? hexacopters aren't out of the question. where can I read more on this stuff? I need graphs and numbers!
I keep looking but all the videos are specific to drone racing characteristics. What’s the beat prop format for stable flight, power efficiency and reducing vibration??
A spinning prop with more blades will likely act more like a parachute, hence why when cornering it feels more locked in rather than drifting around. Up-side-down hang time could possibly be improved regardless of blade direction simply cause the 4 blade is spinning and is providing more resistance from the air thats bumping into it as it falls.. The difference may not be much, but possibly some people are noticing it especially when compared to a 2 blade flying.
wow nice vid i just bought 6 inch and it felt very non responsive and i thought something was up wit my receiver never mind and I've recently started to fly in rate but when i do flips there really wide do u guys know how to make the loop tighter
+George Posey I have yet to see a battery can really provide more than about 45-50C for more than a few seconds without dropping voltage through the floor. I'm still looking, but IMO if you use about 45C as your guideline, you won't go wrong.
+George Posey C ratings aren't always accurate. If you want a good battery then look at the lipo brands that Steele, Skitzo, FinalGlide, Charpu, etc. are using, and use those. SMC, Lumenier 60Cs, Thunderpower, RMRC, etc.
Thanks and great video - answered a lot of questions I have had. In regards to a purely acro LOS quad, such as the Warpquad 230mm using 6" props. Why would a 6x4.5 prop be ideal when it can be a little less responsive than a 5"? Thanks again.
Just built a Butter Kwad with HQ props 6045, Brotherhobby Returner R4 2206 2300kv, Kiss setup with 24 ESC and 4S battery. On first two flights broke a blade when punching at around 90% throttle. Is this faulty props or have a got the setup wrong? Currently flying with no problems with 5" triblades but would like to go back to the feel of the 6" single blade.
On the weekend I lost a blade on one of 5x4x3 triblade going through an invisible tree branch. I tried to regain control for softer crash and may be took another 2-3 sec before hitting the ground. I burnt out the motor with the missing blade in the process but rest of the frame got away ok. Can pushing the motor with missing blade burn it out? I imagine a missing blade on a tri would be extremely unbalanced and puts a lot of load on the motor??
Loving your videos guys, thanks for educating us all in this great sport. I'm really curious about your battery habits, how many you have, do you have different batteries for racing and practicing, how many cycles do you normally get, do you break your batteries in.... would love to see a video on this. Keep up the good work!
Great vid guys thanks very useful! I would also like see a vid on PID's and also a talk through on some of the tricks you pull off in the air. Maybe a slo mo with stick controls in view so we can get a feel for what your doing. Cheers
Cheers guys! I never thought about props wanting to flatten themselves like that. You know what does that noise worse than the gemfan 5030? the gemfan 6030. I always just thought it was vibration.
any recommendations / charts on weight to go with the prop selection? what are your rigs weights wise per prop that you use?; great video guys ! really good info!!!
Thank you, Great video, very informative. Question... why not collective pitch prop on each motor, controlled by the flight controller? Like active traction control. Thanks again you guys are great!
All parts of the loop will be affected somewhat. It may be different for each though. On my quad with a 5x4.5x3 I have the d gain right at 100 in cleanflight. With a 6x4.5 I have it at 20. P is not quite that dramatic of a difference but it all changes. I gain might not be quite as noticable but if your getting it tuned to perfection that will definitely change too.
I come from flying nitro helis in the 90's.With long, heavy weighted blades. Gyroscopic precession was a very real problem for me , and I would find myself always flying clockwise circuits. Flying anticlock (against the rotor) always felt very weird to me. Coming over to quads was a joy, as you have 2 props spinning in one direction, and 2 props in the other...So the torques sort of cancel out.
I.e do the ( # x # x # ) numbers mean: 5x4x3 = 5" prop, pitch is 4" per rotation, 3 blades? And are they always in that order (diameter, pitch, # of blades)?
HELP! I just got the Eachine Wizard x220s and when I put the prop on it spins freely I can hold the motor and push it and it will spin a few times. There is nothing on the internet about this. I was thinking to put the prop nut on tighter but that didn't work. Do any of you know what a good replacement prop would be?
really interesting, thank u guys ! :) Is it possible to get a sneak peak on ur settings for the KISS FC ? I know that the PID changes from quad to quad but i would like to know how did u setup ur "RC Rates, Rates and RC Curve" :) Still working it out on my ZMR250 :3 Anyway keep up the good work! Cant wait for ur next video!!! :))
OK that's props...Thank You!! How about what spins them?? Motors; sizes, wire gauge, number of turns in the windings, weights vs power. Basically the SWEET SPOT motor for what you guys do. There are a ton of manufacturers and price tags, just curious as to what you think is the ideal motor for each flying style that you were talking about with the props... Tall order??? Thank You !! Love this channel
Guys thanks for the review very informative, been playing around with different prop sizes 2 blade vs. 3 and 4 blade. You did a great job explaining the differences 5’ tri blades works best for me, now I know why.
I think we need an episode where you guys race quads against the top gear guys in cars... make it happen!
Yes!
The old original British trio not the new twats
+Grespino 1 For sure! on the new Amazon one...
The Grand Tour.

I still have a big bag of Gemfan 5x3 props if anybody wants them. They are great for mixing epoxy and stuff like that.
lmao...
I have a tonnnnn myself haha
Nice...
I love it when you elaborate on the technicality and still keep it understandable. Best review of the series for me. Thanks a lot guys!
You guys gotta make update videos like these!!! These type of vids are what get people into the hobby!!
Chad tried to get me to blow up my thrust stand last night testing these props :) the HQ 5x4x3 pulled almosgt 1300grams!

Thanks for the prop class. Students totally got it and now want to test props thanks for the class motivation.
Really good video, maybe the best one! Everyone that builds/flies drones should watch this!
great tuturial guys helps a lot , its a mine field, hq 5x4x3 for me, tried 5x4x4 feels very locked just missing something that the triblades give.
Awesome video! It may have been worth while mentioning prop balancing though! It reduces vibrations, and increases efficiency - RPM for those of you curious!
excellent explanation guys, this explained for in a few minutes than most of my online research. Now you should do a video about prop materials.
Thanks for the information guys. As someone new to fpv this helps tons.
seriously 1 of the most informational. vidz out.. it answered all my questions. thank guyz.

Or paste a link to the video where you explained it.
Thanks
This channel is my heaven
Great video!! Very helpful, you are doing a great job. Btw from my personal experience, harder the props more damage to the motor durring a crash. I used sone Gemfan 50x46x2 BN and bent one of my motor shaft...
Sweet vid, makes it simple.
Would like to see you guys discuss your FPV setups some time - What cams & VTxs you use, how many MW, which antennas you use & why.
thanks guys.... very helpful!! what about 6 blade props have you tried them?
You guys should go over your process for tuning PID's and rates. I know that would help a lot of newer pilots like myself, great job guys!
Love the car transmission analogy for prop pitch. I understand the trade-offs now.
Learnt a lot there - thanks. I'm hooked on the speed so I'll not bother with the four blade tris.
what frame, prop size, motors, etc. would you recommend to carry 2 gopros and still be nimble enough to do flips, come out of deep dives, turn really tight corners, etc? hexacopters aren't out of the question. where can I read more on this stuff? I need graphs and numbers!
I keep looking but all the videos are specific to drone racing characteristics. What’s the beat prop format for stable flight, power efficiency and reducing vibration??

great vid.. I've had a lot of luck with the new gemfan 5050 triprops & my 1300mah lipos still have long flight times
Very informative and one of the best videos you've done.
Thank you very much, I learned a lot here! keep up the good work!
wow nice vid i just bought 6 inch and it felt very non responsive and i thought something was up wit my receiver never mind and I've recently started to fly in rate but when i do flips there really wide do u guys know how to make the loop tighter
thank you! how about those battery's and there discharge amp draw for noobs? has rotor riot already discussed this?
+George Posey I have yet to see a battery can really provide more than about 45-50C for more than a few seconds without dropping voltage through the floor. I'm still looking, but IMO if you use about 45C as your guideline, you won't go wrong.
+Joshua Bardwell thank you
+George Posey C ratings aren't always accurate. If you want a good battery then look at the lipo brands that Steele, Skitzo, FinalGlide, Charpu, etc. are using, and use those. SMC, Lumenier 60Cs, Thunderpower, RMRC, etc.
Thank you guys so much for this...as a noob..this has been on my mind for awhile...cheers:)
Thanks for all the advice guys
It has been really helpful
very informative guys. can you do an episode on matching prop to motor to esc to battery please
great point
And come full circle with tuning?? Please :)
Thanks and great video - answered a lot of questions I have had. In regards to a purely acro LOS quad, such as the Warpquad 230mm using 6" props. Why would a 6x4.5 prop be ideal when it can be a little less responsive than a 5"? Thanks again.
I also see the force multiplier or electromotive force in the hypetrain race quad motors and the dewalt electric saw blade - Thank you.
Great and informative video, learnt a lot about props from this!
Just built a Butter Kwad with HQ props 6045, Brotherhobby Returner R4 2206 2300kv, Kiss setup with 24 ESC and 4S battery. On first two flights broke a blade when punching at around 90% throttle. Is this faulty props or have a got the setup wrong? Currently flying with no problems with 5" triblades but would like to go back to the feel of the 6" single blade.

I imagine a missing blade on a tri would be extremely unbalanced and puts a lot of load on the motor??
i have a bugs 2c and i'm going to put a gimbal and landing skid and until now i don't have idea if what i'm going to use if 2 blades or tri blades
Thank you for covering props!
you guys are doing a great job even for the newbiee like me... is plastic rotors the best solution in practicality? thx newbiee quad man.
I would really like to see your input on PID tuning and input on TPA.
could you add a comment to the weight of the quad and prop spec. at what weight does a 5x4x3 not sustain well
Great information! thanks guy! How about some tuning tips?
Which motor and propeller would you recommend for a 2.5 kg drone with 450 mm frame ?
You guys are AWESOME! I love all your videos and this one taught me more than I learned in High School. Ha!
great episode, we want more like these!
Loving your videos guys, thanks for educating us all in this great sport. I'm really curious about your battery habits, how many you have, do you have different batteries for racing and practicing, how many cycles do you normally get, do you break your batteries in.... would love to see a video on this. Keep up the good work!
I have a question, If you want to run a 5x4x3 on a 15 amp ESC do you run the chance of burning out the esc? lets say on a RS2205 -2300KV motor?
What is the 5 inch, 3 blade pitch that you guys prefer for freestyle?
Great vid guys thanks very useful! I would also like see a vid on PID's and also a talk through on some of the tricks you pull off in the air. Maybe a slo mo with stick controls in view so we can get a feel for what your doing. Cheers
Cheers guys!
I never thought about props wanting to flatten themselves like that.
You know what does that noise worse than the gemfan 5030? the gemfan 6030. I always just thought it was vibration.
thanks for clearing that up
any recommendations / charts on weight to go with the prop selection? what are your rigs weights wise per prop that you use?; great video guys ! really good info!!!
hi there I have a 250 quod and I wont to do barrel rolls and flips can you do a vid showing how to do them love your vids
I'd like to know if the weight of the prop makes a big difference? what is the most efficient material choice?
A very insightful video guys!
Thank you, Great video, very informative. Question... why not collective pitch prop on each motor, controlled by the flight controller? Like active traction control. Thanks again you guys are great!
+MrGpse Too complex, too much to break in crashes. Look at the Stingray 500, it's a collective pitch 3D quad.
Yea i saw the stingray years ago, thats what made me think of it. But in the immortal words of David Windestål, "Build to fly not to crash" .
I would like to know what part of the pid loop would be affected by going from a 5x4 to a 6x4 prop.?
All parts of the loop will be affected somewhat. It may be different for each though. On my quad with a 5x4.5x3 I have the d gain right at 100 in cleanflight. With a 6x4.5 I have it at 20. P is not quite that dramatic of a difference but it all changes. I gain might not be quite as noticable but if your getting it tuned to perfection that will definitely change too.
Great vid guys. Well explained.
awwwwww... Steele in 2016... nostalgia hitting
What about the propellers torque and angular momentum as seen in Gyroscopic precession?
I come from flying nitro helis in the 90's.With long, heavy weighted blades.
Gyroscopic precession was a very real problem for me , and I would find myself always flying clockwise circuits. Flying anticlock (against the rotor) always felt very weird to me.
Coming over to quads was a joy, as you have 2 props spinning in one direction, and 2 props in the other...So the torques sort of cancel out.
great work on this episode guys! very informative! the information was presented well.
I.e do the ( # x # x # ) numbers mean: 5x4x3 = 5" prop, pitch is 4" per rotation, 3 blades?
And are they always in that order (diameter, pitch, # of blades)?
HELP! I just got the Eachine Wizard x220s and when I put the prop on it spins freely I can hold the motor and push it and it will spin a few times. There is nothing on the internet about this. I was thinking to put the prop nut on tighter but that didn't work. Do any of you know what a good replacement prop would be?
Props to you guys. This video is fantastic!
I want to use 5040 Tri-Blades. What would be the best size frame?
Great video Guys very informative . Keep em coming
I see some planes in the background so let me ask this, what propeller should be used with a 40amp esc, 4s batt, and 2750kv motor?
Nice explanation guys!!! Very useful!!!
really interesting, thank u guys ! :)
Is it possible to get a sneak peak on ur settings for the KISS FC ?
I know that the PID changes from quad to quad but i would like to know how did u setup ur "RC Rates, Rates and RC Curve" :)
Still working it out on my ZMR250 :3
Anyway keep up the good work!
Cant wait for ur next video!!! :))
thanks learnt a lot. i was wondering why people choose to use 4' props and this answered my question
What do you think of dal props?
OK that's props...Thank You!! How about what spins them?? Motors; sizes, wire gauge, number of turns in the windings, weights vs power. Basically the SWEET SPOT motor for what you guys do. There are a ton of manufacturers and price tags, just curious as to what you think is the ideal motor for each flying style that you were talking about with the props... Tall order???
Thank You !! Love this channel
great vid guys thanks for the break down.
Guys thanks for the review very informative, been playing around with different prop sizes 2 blade vs. 3 and 4 blade. You did a great job explaining the differences 5’ tri blades works best for me, now I know why.
5 inch bi blade high pitch is the best
You should do a micro 105 brushed fpv quad build and review. I'm trying to build one and would like some tips/tricks
