    Trim motor upgrade

    Noticing that my trim motor wasn't working, I found that the gear assembly shaft seal was leaking. The electrical motor was rusted and seized. Stopping at a hobby shop that sells RC cars, I picked up this Traxxas "Stinger" motor as a replacement for $20. It turns much faster than the stocker, increasing the speed of the trim nozzle adjustment. I've seen these on Ebay as well if anyone was interested in upgrading or repairing there own.

    Quite easy to do, just disassemble the gear case carefully while paying attention to gear locations. Then 2 screws get removed, and slide off the sprocket from the old motor. Reinstall the sprocket to the new motor, replace the 2 screws, and carefully reassemble the gears inside the case. That's it!!!!

    Good find! You might want to seal up the vent holes on it,To keep the mosture out. Silcone over a layer of Duct tape or something.(you won't be running it as long as in a RC car.)

    I did that a while back on mine. Your trim will almost be too fast. I mean it's going to be either up or down. you'll get used to it after a while and eventually be able to get it somewhere in the middle, but it takes practice.

    The motor/gear assembly sits inside a sealed cover. (except when the seal leaks) Besides, the stock elec. motor has the cooling holes as well and lasted for 11 yrs.


    Nice to see you peeking in on us Addicted.
    Just a FYI for you: The G/F's 750 squeezed out 53.6 MPH on the GPS under ideal conditions....
    Still waiting to use them adapters you made me. Happy New Year!!!!

    The one that was bad on mine didn't have the cooling holes,So they must have used different suppliers on some motors.Mine was so badly rusted that when I open the gear box one of the gears broke. Have a good used one now for it. Still good to know there is replacements available.

    Picture of the gears, in case you didn't pay attention or got distracted in the middle of the rebuild.
