hi guys. i just want to ask if someone had used RAD 400 on their H8? i am currently using the speed 400 race 4.8V with an 8-cell pack which is pretty good/fast right now. it just gets hot always til the ESC stops.

i am thinking how will be the RAD400 on our H8 compared to the speed 400 race. i've read that the RAD 400 is 7.2V right? does that mean it will be a lot slower compared to the speed 400 race being 4.8V? coz i've tried the speed 400 6V before and it's slow just like the stock motor i think. then i've tried the speed 7.2V then (thinking it would be faster), OMG it's slower. then i ask those guys in the store that if i want power, i must use the lower voltage, that's why i am using the speed400 race 4.8V now.

anybody? which is faster RAD 400 (7.2V) or Speed 400 race 4.8V?

have a great day!!!

tnx

you need to go brushless...you can only drive so much on brushed motors with the size and weight of the m.i.
