Hi All
i havent been able to use my car for some time because i have been away from home.
problem is that i heard that without after run oil there could be some serious damage done.
i cant get to it for another few days, so does anyone know what i might need to do with the car to not damage it.
thanks

Rip the engine apart and clean it!!
Hmmm... i think use denatured alcohol to get rid of all the gumming oil, nitro etc. etc. and after that add some after run oil!
hope this helps

few tips.
after finishing a run ALWAYS run the engine out of fuel.
nitro attracts moisture . moisture in the engine is a "BAD THING"(tm)
use afterrun if you plan on storing it for a while. (few weeks? use best judgement) also "mavel mystery airtool oil" works well and some people have had good results with automatic transmission fluid too.
since you are not sure of your engines condition when you do get to it.. take the pipe and header off and rotate the crank till you see the top of the piston. rust will most likely start at the edge of the piston so you can see it... if its not rusted... run it and defuel it properly.. if it is rusted its not a judgement call for you. you can take it apart and and resurface the piston with ultra fine steel wool (not sure of the grade but there is steel wool that is REALLY fine) of the rust isnt too bad... or replace the piston and sleave if its bad...
note the bearings could aslo be rusted... so when turnign the engine feel for any grinding.

If it's only been a few days, there shouldn't be a problem, especially if there's castor in the fuel. Depends on how humid it is, and your karma
Alcohol attracts moisture (hygroscopic) and Nitro forms an acid as a by product of combustion. Methanol makes formaldahyde, all are nasty to engine internals...But castor leaves a film on everything it contacts, so it'll last for awhile. Best bet is to use an after run oil tho, if you're gonna leave it for awhile. Go to the "Glow Engines" forum and search after run oil, there's a bunch of stuff about 'em there...P.S. Aluminum doesn't rust, it corrodes, and the alum. piston ain't gonna rust. The rear bearing and crank are usually the first to get it, because of the alcohol, nitric acid, etc. inside the crankcase. That's why it's best to pinch the fuel line to shut off your engine...
