I am building a Terminator 2 chassis Clod axle truck. I need 2 esc and 2 motors. I have 2 80a turnigy esc with 2 3520 brushless motors with 13 tooth pinion.

I recieved these used and I cannot get the 2 esc to synchronize. Front will start then the rear will finally kick in, or sometimes I will hit reverse and only the rear axles will turn at all. The wires are reversed between the esc and motors. I bought the programmer and they are set the same and I have reset them a couple of times (pain to hold all those buttons and flip on switch at same time.....). So in my frustration and knowing these are entry level electronics I am considering buying new esc's and maybe a motor combo. I have a couple of thoughts, I am hoping some experienced drivers can chime in and help me.

Is it better to have a higher KV and run smaller pinions or lower KV with larger pinions? I am not happy with my current punch (using 2s). I have read drivers having 3200kv up to 5200kv in competition trucks. My current situation is also a bit handicapped with the esc's not in sync.

80a vs 120a esc. Will I notice much difference with the clod setup? These get halved running dual right?

Brushless motors are killing me. Some post KV, and some like Reedy list T. Makes it difficult to compare apples to apples. Is there an easier way?

If you want, you can just list the esc, motor and pinions you think work best. I am looking for something in the middle cost range.

Thank you in advance.
