Rc18t Help

[Slugger00]

I am in the process of upgrading my RC18T. I mainly bash with some friends and have not considered racing. I mainly run offroad and love to jump my RC18T. I am looking at putting a brushless system in my truck. I have looked at the Mamba 5400 or 6800 and the Tekin performance systems. Both seem really nice but I am "trying" to keep my cost down. I have seen cheaper brushless systems but there were for airplanes and from what I understand they would not be able to handle to surge of power and possibly fry the speed control. Anyone out there have any suggesstions? I plan on using GP110 6-8 cells. Not going lipo due to cost.
