Feigao Mix Up....I Think?

what are temps like?

Yes, I am pretty sure I have a 7XL that is actually a 6XL, because it's way too fast for a 7XL. I did some calcs yes, and compared the proper gearing with my 1512 3D on 7s2p A123 and the "7XL" is much faster, when they SHOULD have the same top speed. I am sure it's ~7mph faster...

It ran BLOODY hot too, 220+F after some runs.

I think it's probably that you don't have enough tire ballooning factoured in. Buggy tires can still balloon .5-1"

Well he does have the wrong value for ballooning, but still, not enough ballooning to go from 35mph theoretical to 55mph real world... do you know what those tires would have to look like?

like my savage tires at 50mph+. they go from stock 5.5in to about 8 or 9 in.

My 13xl was WAY faster than it should have been until it blew up in my Muggy

I would have to have over 1.5" of ballooning to get to 55mph and I can physically see they aren't ballooning anywhere near that much. That would also almost double the size of the original tire. The calc uses the radius so you have to double that to get overall ballooning. Temps are pretty close to 200F.

Yeah, they did send you the wrong motor then. I guess just sell it or try to return it, but I'd imagine feigao's CS sucks...

Where did you purchase the motor? Just return it for a properly tested one.
