Wow thank you for posting this video. Ever since the first time I saw indoor FF planes at the UNI Dome in Cedar Falls Iowa I've wondered how it all works. Very interesting and I think it could be addicting. Like RC lol.
What propeller did you swap to at 14:02? My plane is having trouble climbing, and sometimes just glides down from where I let go. I usually put in about 1350-1500 turns using a 1:15 crank. I'm trimming, but it seems like the propeller did wonders when you swapped, where could I get it?
That's a Papatong 24cm prop. Don't expect it to work miracles, it requires a well trimmed airplane. It does open up some performance options. They're on my website. In terms of your plane, have you shimmed the tailboom to keep the nose up? Which propeller do you have?
@@joshuawfinn I’m using an Ikara 24cm prop, balanced and supported with a carbon rod on each blade. I’ll trim tomorrow, and then reply to your comment if there are any issues.
hello, i just wanted to ask, what should we do if there is a small hole in our covering film on our wing? is it fine if we just tape it or what do you recommend?
I presented everything I could on trimming those planes in the flying segments of their respective videos. They all flew pretty nicely with the right adjustments. The only thing I would change is to reduce the wing twist on the Freedom Flight airplane so that it recovers better from ceiling hits.
I would recommend against it for indoor. For outdoor there's an advantage to be had for non-FAI classes where preheating is banned. Don't go over 100F/38C.
Hi! Thanks for the amazing video, my plane is flying much better now, I just have one question. I accidentally snapped all of my rubber motors and threw them away. Would I be able to use any large rubber band that weighs less than 2g for my rubber motor, if not where can I buy some more?
Hello, l have a question regarding your plane. Do you have any tips on how to get the most out of your motor before it snaps or needs to be replaced? Thanks.
I have my front wing very far back on the broomstick so it doesnet stall, I feel like it’s robbing time since my plane just goes to the top of the ceiling and then goes down. It does not cruise at the top of the gym at all. Let me know what you think, thanks!
If you've had to slide the wing very far back, you probably used too much glue on the tail. The other possibility is that you shimmed in too much incidence so the wing had to be slid back to prevent power stalling. If it is coming down in a dive, that's what the cause is.
Hello, I’m in science Olympiad and it’s my first time doing flight. We’re using a a freedom flight kit for division b for one of our planes and a ward’s science kit for the other. Could we try applying the advice you gave for the stinger to our planes, or does the same advice not apply to all planes? Both our planes are diving so far and we were hoping to improve them the next time we get gym time.
Yeah they're a similar layout and should respond similarly. Make sure to set your CG per the plans in the kit with a rubber motor loaded in place before adjusting the incidence angles.
At my completion the ceiling for the gym will be only 26 feet high until the lights. Do you have any tips to get the most time with such a small venue of space in the gym? I was thinking about using a thinner band, not sure if that will work. Let me know what you think I should do. Using a stinger division B(one with longer fuselage). Thanks a lot
In general, the lower the ceiling, the thicket the rubber you will need so as to maintain cruise for as long as possible. Get an estimate of cruise torque and then adjust backoff to get the desired climb torque (wind to full torque then back off to retain as many winds as possible). 26 feet is a decent ceiling height so 3/32" (0.094") rubber will probably be fine. Possibly .096" will be better, hard to say, and it all depends on which batch it's from.
Hello i’m in Science Olympiad Division B, it’s my first year. I just had my Regionals today, i medaled 8th out of 40 teams (10th and higher got medal) and my plane and flown 30 seconds due to too big of a turn radius. I would like to know how to shorten that radius for next year’s flight and just to improve my own currently in my free time. Thank You, you have been a great help.
Check the section of the video where I was adjusting the turn. That's what you'll want to use. Also, in your free time go to indoornewsandviews.com -> downloads -> The Best of INAV. Read everything in there twice. Get a simple plane for a Pennyplane from Winning Indoor Designs, order wood and hardware from indoorffsupply.com, and learn Pennyplane well. You'll learn a ton about flying, math, science, etc and have fun doing it. Once you've built your first Pennyplane (it'll be terrible, but that's OK, your first one always is), go to freeflight.org and find a meet you can travel to and fly with others. Enjoy!
Thank you so much for the video! Quick question; my glider right now is climbing and turning very nicely, however it flies rather quickly and is not always stable. I've checked the wing and tail of my glider, and both look fine, yet it still seems to fly very fast. Do you have any suggestions to improve my glider?
@@joshuawfinn Sorry for the vague description! To clarify, when my glider flies, it climbs up very high and glides downward with nice turns, however these turns are very fast and the glider does not spend a long time in the air. Additionally, once it is done climbing, the glider will occasionally wobble and rotate slightly (horizontally).
First off, how heavy is it? Build your next one with careful attention to using as little glue as possible, especially avoiding thick, long beads of glue. That's where the weight comes from.
Hi Joshua, My stinger isn't really staying in the air very long. Like I mean it will climb up to 20-30 ft then just go back down. Like in your videos I can see that your planes are like slowing going down. I have trimmed my plane and I'm doing 1000 turns so I don't know what to do. These flights that I do are topping at 1 min. I will usually have 400 turns left in flight, I see that there is a lot of power left in the plane so can you please help get my plane staying in the air longer. Thanks!
It's possible that you used too much glue and it's heavy, however you may just be flying with the CG too far forward. If you are able to shim for less incidence, you'll be able to fly with no nose weight or even slide the wing forward if there's no nose weight, which makes the flight pattern more efficient. Be careful because this does make the plane less stable.
@@ThePixelCubers ok that's progress. Here's a website with some diagrams showing the incidence angle. Incidence and decalage get switched often, for our purposes use what is described as the decalage angle: www.amaflightschool.org/getstarted/learn-basic-aerodynamics
Hello! Thanks for the great video. Unfortunately even with the help of this video my plane still is not getting very much lift. It's turning and flying very nicely, but it is not flying very high up. I feel like I have pretty much gone through every potential problem area, and have yet to found the solution. Would appreciate any advice.
Are you lubricating the rubber and winding to 1300-1400 turns? That part makes a huge difference as well as making sure the prop shaft isn't bent. How much does your plane weigh?
hello! i just had a question about trimming the stinger. how do i make it go slower and in smaller circles because currently it goes pretty fast in a wide circle which makes it hit obstacles?
hi, i just had another quick question. My stinger does not climb much and stays nose-level, and I believe that a reason could be that there is a clicking noise coming from the front of the plane. My guess is that it's the propeller hitting the nose, robbing power, but what do you think? What could be some possible solutions too? thanks!
Verify that it's not contacting anything during rotation and that the prop shaft is straight. Also watch the video I made on modifying IFFS propellers.
Hey quick question, our plane is flying with a very small turn, almost straight. Tried bending the back wing but it really didn't do much, any tips? Also the peak altitude maxes out around 10 ft @ 900 turns, how can we make it climb higher?
Hi, thank you this video!! However, I keep having problems with my plane. At first the plane worked great, and the only problem it had was that the turns weren’t tight enough. But I followed the video and bent the wing of the tail. When I tried my plane the next day it would put it’s nose up and the tail couldn’t support the planes lift . So then I tried to move the front wings up and added mass to the nose of the plane. But then my plane had to much lift and sort of did a flip, when I tested it. So finally I tried to add more weight to the front wings and made sure that the cg was still under the wing. It was, but now I don’t know how to fix the plane when. Any suggestions?
check that your tail boom is still in the same spot, maybe it got pushed a little bit backward and the shims made the decalage change by a couple of millimeters.
Hello again, I was wondering how I could slide my wing forward without having my plane stall, I have added no shim. I'm using 3/32 loop with 1200 turns, going to try to get 1300-1400 winds. Also, If my plane is going above the height of the gym with the 3/32 loop should I lower the wing stab prop so that it does not hit the ceiling or should I just lower the turns? Love your vids!
Don't slide the wing forward if doing so makes it stall. Also never adjust incidence to limit climb, just destroys your cruise trim. Use a torque meter to wind consistently to max torque, then back off to torque that will get you safely to the ceiling.
hello! first of all, thank you so much for your helpful tips. my planes have significantly improved in flight times. I just had a question. Whenever I release my plane, it starts vibrating a lot and I know you said in the video that it most likely is caused by the propeller. How should I go about fixing this?
Thank you so much for this video. When our team first built and trimmed their Stinger C about a month ago, they were getting 70-90 seconds. Since then after much testing and many crashes, it is starting out good and at around 5-8 seconds, it starts climbing too much and almosts flips and falls back to the ground. They have tried a bunch of different things, but nothing is making a difference. It almost glides better than it flies. Do you have any suggestions they can try? Thanks.
Sounds like the repairs have added a lot of weight to the tail. You can add nose weight to correct the problem, however the plane is probably reaching the end of its useful life and a replacement should be built soon.
How many turns are you putting in the plane? I winded mine to 1000, and it flew for about 30-45 seconds, the plane flies very smoothly but I not getting good times, do you know what could be up? Using a 3/32 loop
Wow thank you for posting this video. Ever since the first time I saw indoor FF planes at the UNI Dome in Cedar Falls Iowa I've wondered how it all works. Very interesting and I think it could be addicting. Like RC lol.
Give it a try sometime! We have lots of indoor meets around the country.

@@NexusXGG if it's a true Ikara prop with the gray hub, the carbon doesn't help that's only needed for IFFS props. Might be part of your problem.
@@joshuawfinn Oh, okay! I'll take the rods off when I test tomorrow, thank you!
hello, i just wanted to ask, what should we do if there is a small hole in our covering film on our wing? is it fine if we just tape it or what do you recommend?
Small holes, leave em alone. Big holes, patch with thinned 3M-77 wicked in after you lay a piece of covering over the hole.
I gotta build one now.
Thanks for the video Mr. Finn! Will you be releasing any trimming guide videos for other kits that you have reviewed on the channel?
I presented everything I could on trimming those planes in the flying segments of their respective videos. They all flew pretty nicely with the right adjustments. The only thing I would change is to reduce the wing twist on the Freedom Flight airplane so that it recovers better from ceiling hits.
Is it worth it to heat up rubber bands before flying for better rubber band performance?
I would recommend against it for indoor. For outdoor there's an advantage to be had for non-FAI classes where preheating is banned. Don't go over 100F/38C.

You will need to order more 3/32" Tan Supersport rubber. Do a Google search for it to find what vendor can get it delivered to you the quickest.
Hello, I was just wondering what the best time you have seen for division b stinger this season, because I am getting around 2:40.
That's a very competitive performance.
Love your videos. I'm a modeler since 1978. Greetings from Brazil.
Hello, l have a question regarding your plane. Do you have any tips on how to get the most out of your motor before it snaps or needs to be replaced? Thanks.
Lubricate before every flight, use a torque meter, wind to torque while monitoring turns. Most motors handled so are good for 5-6 flights.
Lovely flight and background

Adjust using the rudder, also make sure your horizontal tail isn't tilted.

Awesome!
Thank you very much for the video. It helps a lot! I'm wondering, what if the plane descends very fast?
Is this at the end of the flight or is it diving out at the beginning?
@joshuawfinn At the end of the flight.
@@xiaoxuyuan5343 is it running out of turns or landing with a lot of turns left?
Landing with some turns left, not a lot.
