OK Brian, i thaink to keep the two speed, but if i plan to upgrade motor in near futur, like an 9XL or a Plattenburg BigMaxximum, is the two speed gear will hold on the extra power???
Because on my Jato conversion, with a Feigao 380c 6L on 3 cells, each time that the tranny was shifting into second gear, the second gear exploded in the tranny!!!!

But anyway, with a 9XL or a Plett motor, the extra power will not justify the two speed anyway, right?

And for li-po, don't want wich to choose, i think to the FlightPower 4900mAh, 4 cells, but they cost $80.00CAD more than the MaxAmps HV5000, 4cells.

But somebody here on the forum tell me that the extra $$ of the FlightPower realy worth the money, that's right???

And the i think to the 5 cells too, but thinking that 5 cells will be too violent on the tranny and diff gear.

I'll use this truck only for bashing, with paddle on it, because for racing i've a brushless crt.5.
