The best way IMHO is to use anti-freeze. If you have an old crockpot it's best to use this, but if not you can use an old pan. Please be advised that this needs to be done in a VERY WELL VENTILATED area, outside if possible. Also note that whatever crockpot (or pan) you use for this should NEVER be used to cook food in again.

Disassemble the engine being as careful as you can to NOT move any of the parts. If there is dirt inside the engine and you turn the parts it will scratch the insides of the motor. As you take it apart remove as much dirt as you can. Place the parts in the crockpot and pour in antifreeze to cover the parts. Turn the crockpot on and let sit overnight. This will remove all carbon scouring and leave your motor looking new again. Put the motor back together.

Most cleanups after an accident can be done without having to boil the motor. You can use a cloth to clean up after an accident. Use an old toothbrush to break dirt off that is packed in. Use a little nitro fuel to loosen up dirt. Clean all parts and reassemble engine.

Hope this helps

odd, it worked fine for them

may have worked for a little while but the gasoline is slowly but surely deteriorating the Orings. Probably more like rapidly deteriorating the O rings. the engine will start getting air leaks and will surely cause problems. Just my opinion.

I'm going to go ahead and ask, since I'm curious and suspect others are too...

The caution against using gasoline makes perfect sense...what about soaking it in the fuel we normally run through the engine however?

Nitro fuel is what I use which I believe was already stated

The o-rings and seals are formulated to stand up to alcohol based fuels. On a Gasoline engine you wouldn't want to wash it out with alcohol for the same reasons.

After taking the plane to the LHS and letting them see the wing and such, they contacted Sig and no questions asked...they are sending a whole new plane...WOW I feel alot better now, thanks to all who posted.

That was easy! Glad it went well.

It doesn't get any better than SIG! If you have any kind of problem with their stuff, they always make it right. NOW GET THAT NEW PLANE IN THE AIR!!!!!!!!!!!!!
Let us know how the lessons are going.
