Summit on 4S, help me choose the right motor for the RX8 system!

4s in a MT can be a higher amp draw system. For ultimate durability I would stick to the 1/8 scale systems. Sinvce you mention tekin, and want the sensored startup (sounds like a good idea to me), I would say to go with one of their truggy length motors.

A longer motor makes more torque, and you need alot to et big/heavy tires moving. Anda longer motor handles a load better, staying cooler. I would go with the 2000kv truggy motor. You will have more motor speed, and you can always gear down if you have too much top speed, and reverything will run cooler. 1700kv would be better for 5s or even 6s.

That would be what I would do. Summit sounds like a cool truck, I may get one, and would like a good low speed system, maybe run a MMpro on 6s with a sensored motor, tekin or similar.
