fastboy, thanks for encouraging words!
I tried 6 cells of 2100mAh AAA on the ABC crp.
The test is just to throttle-on in the air.
The result varied for motors.
Result:
Plasma Dash : the same problem(steers left) appeared.
PN Racing S-03 motor: less appeared.
Core midified motor: hardly appeared.
Stock 130 motor: no problem.
So it seems to be a problem of the current draw.
The large curernt causes the servo trouble.
fastboy, I assume you use the "stock" 180 motor, right?
And that's why you dont face the problem, I guess.
But, I still wonder:
According to the specification note, the ABC crp should be able to take 60A continuous, 240A in peak.
But the Plasma Dash requires just 4.1A even ON LOAD. It's relatively small enough for the crp, isn't it? Why such a problem occurs?
In addition, the test above is done without any load. When the car runs on the ground, the current draw will be more, so the problem will appear more clearly...
