I just bought a new ofna mbx pro, starting it with pull starter was a pain and the glow plug warmer was always dieing. So I bought a Q-worlds starter box with a power panel. It has the big single motor (not the small twin motors). It worked great the first time I used it. The next time out it started my brothers MBX and then the motor started to spin the wrong way! So it would try to start the engine back wards! All the wires are hooked up right, I never changed the +ves and -Ves coming off the 12v batt. I don't under stand how the motor would just start going the wrong way! Sould I just change the wires? will this wreck my starter box motor? Also some times it will kick back and go the right way for a few seconds then stop and spin the wrong way again. Its realy wierd. If any one could help me out I would be greatful.

Thanks....Josh

if the starter box works ok for your MBX, then it is imposible for it to start your brother's MBX the wrong way round.
I think the gear box in that car is assambled the wrong way round...
... your discription..." start the right way for few sec... then spin the wrong way again..." to me is a very clear indicator that the engine is ok, but the front/rear diff is the wrong way round...
I had my Inferno run in reverse also the first time I venture into ic car.... lol.

just check that the car is assamble the right way... if not... then something weird is going on....

I would say that there is something wrong w/ the electric motor. It shouldn't just change directions. You might want to either return the starter box and get another or just get a replacement motor.

The box starts both are cars backwards now. It first started them the right way then it just started spinning the wrong way! I bought the box on ebay so I can't return it! It was only used a few times and appered to be new! I took apart the motor and it looks fine. I think I'm gonna put a reversing switch in it so when it screws up I'll just hit the switch and it will spin the other way! But for now I will sit and wait for my Car parts to showup, Last time out the radio died and my car took off full out and smashed in to a parked car! The front ends all busted up.[]

Sounds like you may have some wires crossed or something, on an electric motor if you change or reverse the connections the motor will turn the other way.
Make sure your wiring is in order and if you do not find any problems, just swith the wires on the motor to get the desired direction.

Also be sure your power panel is operating correctly when you switch.
