Jim,

A friend had one (flew the stuffing out of it then sold it...) and I was looking at it one day ans saw that he only had what looked like 1/4" of throw in the elevaors. Go by the book on the throws. It had very little throw and if you hauled back on it, it would snap. Tame down your throws and I'll be you'll be okay. Oh, and I've also read that the OS 160 with the Bisson Pitts muffler needs one hole plugged up for it to have sufficient pressure with out using a pump or regulator.

Good Luck.

Jon
