Wow, even Dean Pappas chimed in!!!
And absolutely right! In fact, you'll probably be quiter than most of the 4-strokes at your field, too.
I used to run YS .60Frs in my Deceptions. I ran 10.5x7.5 props and the YS HONKED and so did the Deceptions. I stopped running pylon props when I had aileron flutter in one of my Deceptions. Lasted less than 5 seconds (maybe more like 2 seconds) and ripped out the aileron servo, stripped the gears, broke both aileron pushrods and ripped off one aileron. Fortunately I got it back on the ground safely. The noise of those screaming engines was impressive, but not too healthy. Years of tuning screaming 60s resulted in some high frequency hearing loss in one ear (my tuning ear). Of course now I can't hear my wife with that ear..... so there is a silver lining
I gotta build another Deception myself!
