RE: Why should I use a PCM receiver
I sold my 140L long ago and got a 110 for the Showtime. Lighter, and good power-to-weight ratio for the airplane. I figured I can do almost anything with ST without the extra cost of running a 140. The stock muffler is prety quite. 15X8 APC @ 9000 RPM. The dry weight is 8.5 lb.
