Goingstraitup,

Thanks for the warning. I have dual rates on my Futaba 6DA (I think I was the first and last guy to buy one of these TX) and use them on my RCM 40.

I'm putting an O.S. FS-70IIS with a 13 X 8 prop on the Contender. At mid-range RPM I am hoping it will cool down a bit. My club has a soft-rule that you don't have to first-flight your own airplane (unless you really want to). Even some of the very experienced fliers defer to the "founding fathers" for hot or experimental birds. We have a deep bench of pilots who are semi-pros in R/C (I am amazed at how often I come across names I recognize in old or current magazines).

I can't recommend or relate highly enough the difference an instructor made for me. Like many guys here, I tried on my own years ago and only succeeded in planting an otherwise functional engine in the ground under a heap of balsa.

And sometimes it is much harder to learn from someone you know and love as opposed to a better prepared stranger.
