First of all I'm new to this forum so Hi everybody :) For past 2, or 3 years I was playing with making best rc car from lego. I have made a lot of projects of random cars. It starts when I realize that I can plug PF small motor to my receiver from remote controlled helicopter. Yeah this project will not include traditional PF IR control or something along those lines. And also I'll probably customize some parts so if anyone is offended by stuff like this, just don't be too harass for me :)
So, plan is to make lego drift car. Yup actual RWD drift car that slides like every other rc cars (okay maybe a bit sloppyer). My inspiration here is Toyota AE86. I started making chassis:
It was actually hard to figure out. I needed to make pretty big steering angle, and good way to control it. Also I modified pf small motor, by replacing dc motor in it for much stronger, and faster one. This motor needs gear reduction (I find 1:9 works the best), so I made small simple "gearbox" behind that seat.
In the back, we have live axle with "welded" diff :) I also swap springs with Technic hoses for stiffness. It's only for tests, if I like it I'll probably do the same in front. Everything will came out after tests, but I'm currently waiting for tires.
This is the steering angle that i end up with. It's not ideal(yeah I would like even more angle), but It will work for this build.
That's all of my progress so far. Everything still is a prototype, I'll probably end up changing a lot. I also hope that I have enough parts to finish this build.
If you have any questions feel free to ask them. I'd love to hear some feedback from you.
Take care everybody!
