Well it had to come,

So we had a group of local kids and adults come to the field for a fun day of learning R/C flying. They are from a Farm group and were very interested. Well My plane was used for letting kids try it out. Well one thing led to another and the instructor got disoriented and didnt recover from a dive. So needless to say, the plane drove into the ground. Well now Im left with the motor needing help. What should I do?

The carb is packed with dirt. What should I soak it in?

Don't turn the engine over! Gently brush or pick away all the dirt you can see. Inspect the outside of the engine for cracks or other damage. I would take off the carb and soak it with water to get the remaining dirt out. I then would take rearplate off the crankcase and the head of the engine and flush with Varsol or WD-40 then inspect the inside of the engine. Only after you are sure the dirt is all removed would I oil up the engine, re-assemble and start it.

don't use water use denatured alcohol.

I would not recommend water either. I use diesel fuel as a wash when I plow one in, outside never indoors.

Don't turn engine over, don't move throttle, get you some carb choke cleaner (cheapest you can find) spray it out.

Justin,

Sorry to read about your bad day at the field.

Regards!

Well I may be in the minority here. put it in the sink with soap and water. Brush all the dirt out with a tooth brush. Take it apart wet and clean it all in the sink. Dry everything and then it as you reassemble.

I have done this to way to many engines. Water will not hurt them as long as you dry them and then oil it as you put it back together. The worst dirt I have ever seen packed into an engine is the clay from the Imperial Valley. I had red stains on the aluminum. I call it super glue mud. It sticks to every thing.

Yeah you do nice and you get this as karma LOL

Oh well, Noone was hurt, thats what matters. Thanks guys for the info and help!

After tear down I dont see any cracks at all and it looks pretty good! The only thing I think I really need is bearings. After a thorough cleaning when I turn the bearing it has a small "catch" in it. Kinda feels like might have a bit of grit in it maybe. So I figure Ill put new bearing in and go from there.
