[R-390] Ultrasonic cleaning

[barry williams]

That VT-240 is a treasured engine now. The pumped 120 had a good 
reputation, but parts have dried up for them.

I got into RC since I'm not flying full scale any more. It helps satisfy 
the flying urges some. My flying days are over too due to the medical 
thing. I sure miss flying at sunset. That was always the best.
