thanks I got the 4.5 motor, I might get one for a tuning option anyway. I here people talking about motor temp and over all gearing of motors alot. I'm all new to the electric stuff, I'm use to nitro and I understand that an engine that is to hot is not an efficent one. Is that the same for electric motors? to much load one the motor? How do you calculate the gearing? On the jrxsr page I see it posted alot for the 10. - 8.0 seams to be an average. But you can look and look and there are way to many pages to find the info you are searching for.
any light shed on the topic would be great
