Hughes TH-55, 269 (Schwietzer 300), Class 65-10, US Army
Have flown and instructed in most all Army stuff thru 1969; Bell47, Hiller UH-12, Hueys, Sikorsky's, etc
After 1969, full time airline pilot, part time continued to fly/instruct most all small civilian stuff
Bottom line..IMHO...the R-22 is the best trainer ever built. It has the economy of operation for the school, and it has flying characteristics most conducive to student transition to all larger machines.
Oh Yeah... I think I have read every word Lu has posted on this and all other forums for the past year. I just wish he would simply attend a RHC Safety Course.
