Ok, what if I use a this:
http://www.amainhobbies.com/product_...ess-Motor-175T and then the 4:1 reducer. with 1900kv, would that be a good powerhouse? Or should I go 4:1 with an equivalent 27T? Brushless is more expensive, but I might be willing to pay more due to better chances of it working, as I've had bad luck with brushed motors. It's going to take a lot to get me to trust brushed motors again. Every one of the 11 that I have owned has blown up, except a 14T Losi, and even that got close. I've never blown a brushless motor.
So then I should use the 4:1 reducer to maximize torque, and then what motor would you recommend to use with the 4:1 GRU, that together, would equal a little less speed than a 55T without a GRU?
