Need new motors? Grind a gearbox? Adding teeth to a pinion?
#147183
Hello Powerwheels folks!

I read thru the battery FAq...and its a huge cluster.

I have a powerwheels f150 and my oldest son is 55 lbs, younger 35lbs...hilly terrain. I bought my fist upgrade, 16AH lipo battery 4 s (16.8 volts max). Ran great for a while....but stock motors burnt out. Unit is 5 years old at least.

Im looking for the most reliable motor setup given my voltage. Not looking for speed, just power to climb hills with kids.

You's think it would be a simple problem, right? Many of the rc car motors are designed for 4s lipo...looking at traxxas titan 550 23 turn, HPI "14.8v" 550, or trazzas 775 titan. I have 16 tooth 32 pitch pinion. Its my understanding with 775 Id nee a 5mm shaft pinion, 3 mm with 550 . Plus apparently some sort of "spacer" and different screws to bolt 775 motor, but I see two sets of motor mount screw holes on my gearbox and I have read powerwheels gearboxes are designed for either size motor.

Im looking for bulletproof performance. Apparently theres a need to remove the active braking too?

Thanks! John
