Joseph, you have taken every so called radio controld rc tech , how to, and instructional video and blown them completely out of the water! You have set a new standard for the rest of the "PRO" racers to step there shit up., and have done more for technical side of RC than all others combined that I have seen since i got into nitro 20 years ago! THANK YOU!.
Dude it's got to the point where I like video before I even watch, cause now as the rc community we need to make this channel successful. Info is too valuable and most watching TH-cam don't really do books.
Wow the amount of valuable things I've learned from you is incredible. You probably understand more about the physics of horse cars work better than most designers developing these cars.
I know all your videos are focused on 1/8 scale, but my son is moving into 4wd 1/10 classes in the coming year and some of this is really helping me understand more about how things work. Thanks for the videos. Hope 2021 will he a good year for us all and for RC racing in general.
Most of the guys will never understand the value and the effort this guy is giving to us. I did also study mechanical engineering with more classes about cars and all those things he is talking would have been an entire discipline, body roll, roll centre, geometry modification while body roll, C.G. etc etc. it's a very complex thing for a regular guy like me and for sure for most of you but exploring all the different geometries is what guys are being paid a lot in F1 cars. There are books only talking about these things and I'm not talking in R/c cars. So my last words would be many thanks for the incredible work you are doing and the time you need to spend on these videos.
JQ, this is the first time ever I "hit that bell icon so that I don't miss any new videos ever again" and that's without the youtuber shouting that sentence at me 10x over the course of a single video. Awesome content.
This is extremely useful information. Would love to hear some information about the front end in 2wd applications where the front end has no driving or braking forces. Also would like to know how different castor angles change the steering and handling characteristics.
The X ray doesn't have any front camber adjustments. It's factory set at 2 degrees unless the stop bushing is removed. It's basically a shimm that can be removed and then you can adjust camera wherever you want
This science is something I never knew about, as a non-racer. It reminds me of rake and trail with motorcycles (in a way). When the rake&trail geometry is wrong, you can have either dangerous steering or very heavy, sluggish steering and handling. Thank you for this!
As an Engineer and Designer, most my work are with aeronautic structure (most of them dimynamics) and CFD analysis. See the rc cars and your and their videos. Look's like the brands invest more on make new cars fast for selling new models and empirically improve those cars, more than really studied and analyzed the dynamics for make better models. Just my overview of RC cars now.
Another great explanation. But you know I have questions. Scrub radius and offset turning moment - is the turning due to an actual turning of the wheel due to rc cars clearance in the joints which won't happen on real cars, or is it a force about a point which acts on the chassis in the horizontal plane ? And why is only the lower arm outer pivot used to calculate offset on the rear ? Does the top rear arm angle affect the Kyosho example of grip under brakes. loose mid corner and grip on acceleration ? I subscribed and looked at the book but exchange to NZ is really expensive? Really enjoying your videos.
Serpent has the inclined king pins as well. Hopefully you can do a video with Billy Easton talking about the engineering behind in the making of the cars.
Merci Sacha pour cette video. Maintenant une petite video pour nous expliquer comment regler un caisson de basses serait le graal ;-) AV concept au top. Cdt
okay okay, so this bit of info was actually quite crucial when it comes to different chassi setup on the same track. I shall re-watch this video now, and take notes.
Nice review! Let’s see a video on all the winning IFMAR 1:8 nitro buggies and what they all have in common or don’t have in common. Kyosho holds the most wins for a certain time period. Why was this? We’re they so ahead in 1:8 development?
So by putting a narrow hex on the front of a pillow ball car, wouldn't that be increasing the negative scrub radius? It moves the center point of the contact patch even further away from the intersection of the steering axis, making the front end even more numb adding to that toe-out force?
Thanks thanks J. i apreciate the goods explanation and the hard work to find examples..i m not a good rider but i like to much understand the phisics that i don't takecare to change something on the car..thanks again Pralong from Argentina
Thank you so much for this video! It really helps me to understand my car (Mugen) a lot more and where to start tweaking adjustments. I really enjoy these science type videos. Just subscribed. Keep up the great work, and I look forward to more in the future.
This is brilliant stuff. Once you explain things it is very hard to listen to others try to explain car handling and characteristics. please keep it up. I ordered your book. thanks
So I’m listening to this while driving and it’s very informative but am I correct in saying this? - you can adjust a C-Hub to drive exactly like a pivot ball, and vice versa.
You are right. Buddy. I own a Mugen I feel that in the track. When you exit the corner can’t settle the front until I get corrected then I can accelerate. So I went toe in , but now I lost turn . Can’t make the car turn on power. Crazy what your saying it makes sense.
Great content Joseph! Question to complicate matters. Talking front end we know all this is static with 0 toe and no variation through the corners. But I would assume you can negate some effects you mentioned with bump. So you mentioned a PB car toeing in under braking, but in real world scenario you have weight transfer to front and front diving under said braking. Most pillow ball cars have a lot of bump out at top and bottom of stroke. So if the natural neutral tendency is to toe in, is the effect negated with a certain amount of bump out at the top of the stroke?
I think it can help to negate it, but I think the direction of the force still matters. Also I don’t understand the reason for large amounts of bump steer, in my opinion it makes things worse every time
I have ran hyper 7s for years and will be for the foreseeable future. I can run both front and rear either way. For me, hubs give me more steering and would be my preference except, I find balls to be more durable so I run them in front to assure that I finish the race.
JQ.. honestly, the thing that makes you different from other rc related youtubers is that you are honest and don't give a shit what other mfg will feel about your video. Other guys would say stuff to cover their asses... but you don't... which is an asset to your video. You would be like the "howard stern" of the rc youtube industry. BTW ... a request... since you are comparing buggies with other buggies ... can you do one that talks about the new Tekno and HB buggies. thanks for your time.
My lawyers do not enjoy my content. Watch this space...lol. I will never spend money on anything tekno. If someone sends me one I can give my opinion :-)
Way to go man, finally some nice useful info here from someone who knows what he is talking about vs all the usual bs that’s floating around you tube .
Hey man I just uploaded a video about rearranging the electronics on my xray xb8e, I tried to share my idea wich is really nothing new but anyway will you go to my channel and take a look it’s only one video for xray, I am new to the hobby but I use to race cars and set balance correct... let me know what you think
It's mostly driving. I'm a very nervous driving and u run the slowest laps but I fast driver can drive my car and be the fastest driver on the track, with my car and I'm slow
this is absolutely fucking brilliant information / tutorial. I've been wading through heaps of shite on the internet for 2 weeks and this is the only place i could find proper scientific answers.
Brilliant information! Personally i have ran a Sworkz buggie and always enjoyed how easy they are to drive and how well they seem to jump. What do you think of the latest Associated nitro RC8? I really enjoy watching all your videos and have learnt a huge amount that has really helped my racing. 👍
Very useful video, as I am interested to buy a Mayako, what kind of behavior we have to expect from your car ? Close to kiosho or mugen ? I run mainly on soil dusty track with hole in my regional race tracks. Thank you.
I guess that a car with zero scrub radius in front and no offset in the rear would be great on paper, but awfull on track because at each time would have one kind of reaction, because gaps, and flex, would get the geometry in a random tendence according to the circunstances.
Sorry, also....seems to me these 2 videos support steering both chassis designs both the same way - coasting through the apex and power on exit. So, doesn't seem there really is much difference. If anything, seems the C-hub can be powered on earlier in the corner than the ball - but you seem to indicate C-hub design drivers wait until after the apex which is where I see a contradiction.

The turning moment is there on real cars too and will effect it the same

Got a great deal on the original The Car and it came with The Engine. Cant wait to get it out on a track. Car and motor look high end.

Won't the front of a pillow ball give more mid corner steering due to the effect of kpi inclination? Thanks.

Yes something like that. Let's say that determining for the car how you want it to react, without going too far, seems to be better.
Sorry, also....seems to me these 2 videos support steering both chassis designs both the same way - coasting through the apex and power on exit. So, doesn't seem there really is much difference.
