Dick Hanson,

I agree, the RCS 140 is a nice engine. I have been running one on a H9 edge, not unlimited but very nice.

I know you had talked about a pipe on this engine and I have both the whisper tech and v tech, but never got to try them. I wouldn't have thought about it if you had not mentioned it.

The plane is gone, but maybe I will get a chance to try it with the pipe. Which is better between the two Whisper tech or v tech.
