having bought and assembled this car about two weeks ago I’m puzzled to find this car slowing down (almost stopping) when turning left (bluetooth) and the voltage meter reading going from 9.0 to 3.something. This also holds true when putting the device on a stand und letting the whells run freely. II’ve checked the wiring and mechanical setup multiple times and couldn’t find any issue. On turning to the right everythings works fine as well as going forward.
Do you have any suggestions what may be the cause for that behavior and how to remedy that?
When your car make left turn, make sure the front wheel is not stuck by the chassis. Sometimes improper installation of the front steering system might cause wheels touching the chassis when making left turn(or right turn). In such cases, the car will consume huge current to overcome the resistance. The voltage will reduce sharply when current is increasing.
If you found that the front left wheel is touching any part of chassis during left turn, you have two solutions:
1) Adjust the screws of the steering system, don’t let the front wheel to touch chassis at any time.
2)Change the code, reduce the left turn angle. For example , original left turn and Sharp_left angles are defined as following:
int LEFT=FRONT-25;
int SHARP_LEFT=FRONT-35;
Please change above value to:
int LEFT=FRONT-20;
int SHARP_LEFT=FRONT-30;
Above code change will reduce the Left turn angle by 5 degree. If the the wheel still touches chassis when left turn, you can change the -20 to -15 and -30 to -25 , then try again.

Hope this helps.
