Guys, is anyone using an O.S. .91FX and standard servos (S3003 or S148) on their Goldberg Decathlon ARF? I'm seriously considering ordering one from Tower, but these are the only components I have on hand. I don't plan on trying to make a 3d machine out of this plane, but I don't want to hamstring it either! I tried to download the manual, but Goldberg is charging $4.95 for the privilege.

Can the engine be mounted inverted with a pitts muffler?

Any comments, pro or con will be appreciated.
