Hello guys,
I have to apologyze with you cause I have not been present in this start of the year. Unfortunately lacking of time and bad winter weather stopped me to realize my RC hobby projects. By the way I did not loose the will to share some contents and ideas with all of you and hope with a better season to be back.
I have to say this project was not easy at all for some reasons.
The main reason is that there is very limited gap between the ground and the undertray (about 5-7mm). When the speed increases, the car that is already very low, grinds with the undertray over the tarmac due to the ground effect
I reinforced the suspensions to be as stiffy as possible expecially in the back, cause the car squats pretty much on acceleration, hitting the bottom.
By the way, if the running surface is not very flat is very hard to control the vehicle. So basically, it's necessary to lift the car loosing downforce efficiency. And that's the problem that even the actual F1 cars are suffering nowadays.
So I am very happy to have the chance to replicate this awesome physic phenomenon, but on the other side I got to say that it's very very hard to maximize the performances. The same car with a normal rake setup it's even slightly faster.
Here is the setup of the car:
Motor: SurpassHobby Rocket 5.5 V3 sensored
ESC: Easy Turbo ET120, 2-3s sensored esc 120Amps, basically an advanced clone of Hobbywing quicrun series.
Battery: 3s Lipo 2200mA 120C

I think you'll have good success with this setup... Maybe try starting off with the ride height a bit higher to stop it grinding & hitting the road at higher speeds.? After all, you don't really need the extra grip at lower speeds..? Or perhaps fit O rings to your shock shafts so they can't go lower than a certain point.? You're using the best tyres I think because there's no compression in them.. Remember how Ayrton Senna crashed & died.?.. From his car grinding the track during a high speed turn & losing grip.! Good luck, Subbed & liked & best wishes from Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🙏 ❤️ 📻 🕹️ 🔋 🏎️ 🚓 🚔 🚖 🚗 🚙.

Thank you so much mate for watching and sub. Unfortunately with this kind of small car I have almost zero margin for tuning. The bottom is about 5 mm from the ground with the suspension arms and dog bones shaft pretty flexed downward. This is necessary cause the undertray is about 12mm thick and it reduces sensibly the height from the ground of the car. I can't pull up furtherly decompressing suspensions cause I would bend too much the dog bones shaft that they risk to slip off the diff cuffs. On the other side, with this ground gap the car is really stable and i don't need wings on the rear to keep it on the road. By the way, I have in mind to use a bigger scale car in a next trial. In this way the clearance from the ground wouldn't be so extreme and I could push safely without hitting the tarmac. The caveat is that bigger car, means bigger parts, so it would need more time to arrange the undertray. By the way thanks again for your suggestions and your interest in this project. P.S. Ayrton Senna had that fatal accident due to the steering shaft breakage right in the worse place that it could happen in that moment.
