Help with old gummed up engines....

       Remove this ad - become a site supporter!
Any tricks or secrets in getting my old Tmaxx 3.3 and Revo 3.3 going after sitting for 2+ years.... They aren't seized... but definitely are gummed up as the easy start can barely turn them over.

Worse case is I take them apart and clean them... but if I had that kind of time they wouldn't have sat for 2years! Just curious if any one has some easier tips, suggestions to get them running.

Soak them in fuel or just alcohol. But I would take them apart as there is good possibility there is corrosion on bearings after sitting that long.

If you don't mind taking a crap shoot, I have always got them freed up after soaking.

Electric flying is pretty much seeing how close to a dead short you can run without setting it on fire.

You can't go wrong with letting them soak in WD40. If you have a good idea there is corrosion inside there really isn't a fast way to remove it. Take apart the engine and clean it properly, it will pay off in the long run!
