hi
i've got the lrp sphere comp personally i think it's great i've had it about 3 or 4 months now and have not cleaned the motor yet and it's just like it was when it was brand new i've ran brushed motor on it without any problems too i have had one problem with it it got abit hot and the top of the speedo and heatsink came of but i sent it back and they sent me a new one within a week it just depends on how much you want to spend
