Re: Did castor oil save this motor

Mid April I recovered a Quickie-500 airplane that was lost in a mid-air at pylon-one last July. It was lost in a canola field and after many attempts was never found. Well after the snow left I thought I would take a last look, and see pictures for what was found.

The plane was lying flat with the ground, seems the combine missed her. The mice ate all the wires, electronics are garbage but the Nelson engine after tear down was in great shape.

The piston was at BDC and the shutoff carb was completely shut. The inside of the engine still had signs of Castor oil in it and no rust after 9 months in a field! I thought I would have to at least change the bearings but after everything was cleaned up, and flushed I was surprised, they felt good.

I reassembled the engine and ran in a new Quickee the other day and it runs great. The plane and electronics were lost but saved a $600 engine by using good fuel and taking a second look.

Racing fuel (in this case Riches Brew) uses a mix of castor and synthetic oil, the castor is said to stand up better to heat, and seems it stands up pretty good to a harsh environment as well.

BTW: I use straight Compressor Tool-Oil in my racing engines and never have had a problem.

Nice! I love that feeling of discovery when you finally find a model that was lost for some time...
Good news on the engine too. As much as Castor gums and tarnishes an engine, it does have its benefits!
