After the summer season of rc I will no longer be driving my nitro trucks until next year. I was wondering if there are any procedures to preserve the engine so that it doesnt corrode from the nitro. I have run all the gas out of it and put after run oil in it since the last run. Should I disassemble it and clean all the nitro off the piston and sleeve or just leave it as it?

you can tear it down and clean it up real good. check your bearings, clutch shoes, piston, sleeve,etc... or you can just keep it like it is. as lond as you ran some ARO in it.

well said

i would clean it all up. I clean the motor really good every year by taking them apart and inspecting everything this way the next year i should not have to worry about a dnf in some race i was in. For the motor i check the bearing and on the piston i clean that off with some steal wool fine kind the number for the wool should be 0000 on it i use that to get the piston to look like new all ove again. then i check the connecting rod. If it all clean and up i spray it all down with nitro clean. I then put it back to together paying carfull attetion to the bearing when i oil the and the connecting rod. Then i oil it once a month and move my fly wheel over a couple of time to keep it lubed up doing storage. I try to keep my car in side this time off year too i dont know how to figure out if the garge is too cold now or not so i play it safe and bring them all inside and piss of the girlfrined lol
