Can someone tell me a good place to start with the low end setting on the .91df? I just picked up a used one and it was screwed in all the way. I have another one in a jet that runs awsome but I'm not even touching that one to see how far out it is because I remember what a pain it was to adjust that. One little tweak off and it went crazy. I just cant remember how far out it is!

Oh, BTW, does anyone know if that giant Concorde was ever flown? I saw it in picutres from superman rally a friend took a while back. That thing is awsome!

Say Hawk,

Just for you, I checked two of my 91's and with the barrel just closed, one was at 2 full turns from bottoming out and the other was two plus maybe 1/8 th....

Safe to say that two turns out with the barrel just barely closed would be a safe bet...

I read the instructions and could not find where they gave a definite starting point for the OS 91 fan engine.

I also checked, and I get 1-1/2 turns out on mine. I'd start with Roger's, then go from there. Hope this helps.
