Can the motor be replaced or upgraded?

Thank you for the inquiry. Yes, the motor can be replaced or upgraded to brushless but you need a brushless ESC. We suggest using the factory version motor.

Whats the biggest wheel size i can go up to with the 903a model?

I wouldn’t go much taller because it puts more drag on the motor and makes it hot

Is it possible to get a replacement motor or upgrade it to a different one?

Thank you for the question. Yes, the replacement motor should be a brushed 390 motor or brushless motor which is not larger than the original motor.

What's the battery size compartment? Or what are the dimensions of the batteries that come with 903a?

The battery size is 2S, 1600 mAh 30C 7.4 volts. Battery dimensions are about 1-1/4" x 2-3/4", or about 34 mm x 70 mm, and the compartment is about 1-1/2" x 2-3/4", or 38 mm x 70 mm, with a lot of over-head space (where the cab lines up).
