Good news:
- Fast and powerful little car, tested inside my house, outside on grass and rock,
- My 7 years old daughter can easily control the car,
- Long battery life,
- TX looks and feels good,
- Really fun!

Bad news:
- Reverse sometimes not working at all, bad potentiometer on tx?
- Need too much work to open the canopy just to connect the battery and turn on the car, also for charging, with some risk to loose small parts
- Long time to charge via usb charger.
- Broke the servo at the 3rd run.. i think 50% is my fault , and another 50% because of plastic gear servo fault, front left wheel hit vertical obstacle at moderate speed.

Here's the broken plastic gear servo:

Servo Modification


Since no replacement spare part yet, I decided to mod servo mount to accommodate bigger servo.
I have Emax ES09MA metal analog servo, slightly bigger then original 5g micro servo.

What I need to do:
- Drill two 3mm holes,
- Use 2x thick double sided tape under the servo,
- Zip ties.

My plan: double sided tape + zip ties work as a stiff spring, so servo should be save from direct impact when front wheel hit some obstacle..

Did this servo mod work for you? Mine broke in the exact same place during its maiden run.
