Anyone got any ideas? heres a link to my facebook my pics are on there. https://www.facebook.com/daniel.kersey.982

Sounds like a electronics problem. What motor are you using.

It's that non lipo. When you bind up and start cranking on your throttle, it over draws your batteries to where they can't provide the amprage.

Could be.....

Voltage applied, motor turns, gearing (spur & pinion) & rig weight all have an effect.

A low turn motor and/or high gearing (more than ~5:1 pinion to spur) can make for "road speed" but kill torque.

Using NiCD or NiMH packs is not bad, but they are big & heavy compared to LiPO.

Crappy pack connectors (Tamiya is among the WORST) can also kill power.

Heres an update what I have done. I switched to a 11.1 lipo batt and now its faster than a wrath and still I have no torque. Do I size down the mane gear or the diff's? The motor came with a box of parts, I have know idea what it is but it was in a standard scx10 frame. It seems to be a bit longer that the factory Axial "can". As for binding I have a little from the rear I cant seem to get the pinion angle right.

Yeah dude, sumthins outta wack. Even with your gearing all wrong, you'd be able to climb. You might have to goose the throttle, to get your rpm's up, and your motor would get hot quickly, but climb you would. This is electronics, i think.

well i picked up a rooster crawler esc and im having the same problem so I guess I'll replace the motor and see if that helps.

[JesterSpec]

What gearing are you running on the spur and pinnion?

What motor Specifically? I suggest a 35t to start with.

[TinkerTime]

there stock 28/30. I'm starting to think it is the motor I going to switch to a 55t motor and see what happens. Like I said I have no Idea what kind of motor I have is so thats where I going to start.
