I am planning to use the original plastic wheels, but may change them to rubber wheels later on. Jest to 4 channel receiver from radio link. It has a built in gyro, and this is a relatively cheap esc bought from bing good. It is only for one channel, the mini dualshaft motor. Jest to 1.7 gram. Rotating servo here is the lipo battery 3.7 volts and 70 miliamsy. It comes with the two pin jst plug. This is my chassis, that i 3d design and then 3d printed. These are the front steering knuckles. This is the front crossmember where i designed so it could be fixed, and this is the rear motor mount. Now i usually like to have front lights and rare lights, but for this case, i’ll have to leave them out, because the esc only supports one channel okay, so i finally got everything soldered together and it’s, actually a really surprise. Uh simple: we just have the esc here connecting to the motor and it will deliver power to the second channel, whereas the servo is on the first channel and the battery is on the fourth channel. So the third channel is empty and since i don’t have the led lights here, i’m able to detach the body completely from the chassis. So i am running these rubber wheels, which is really uh hard to put into a drift or a spin. But it has a lot better traction, so it’s been a long time since i’ve had these outside.
