Hey,i recently owned a novak 5.5t brushless system and all i can say is WOW i dont know why people havent taken them on yet,i guess they dont wanna break their routine.
I think they are way better because of the super low maintanence and low battery consuption,dont get the LRP or nosram ones as they have lower punch that the novak,i would recommend the novak 6.5t velocity brushless motor with the gtb speedy...a 5.5 or 4.4 would just be to crazy for offroad.
