Vallon I use an O.S. #8 in my O.S .32... Do have someone look at your heli and test fly it, I did!!! went out with all the stuff needed to fly it last weekend... watched, asked some questions and found someone I felt comfortable with to look over my heli and do the test flight... dam good thing I did. I made several small mistakes that would have cost me the heli had I tried to fly it. Dusty fixed my screw ups and had my heli hovering hands off with minor trim changes, said it flew well... that's how I knew the Co-pilot(installed it after) was giving me trouble until I calibrated WITHOUT auto trim The trim settings went back to within one or two clicks of what Dusty had set for me. So far the Co-pilot has not impressed me... it's still to early to tell for sure though, I've spent LOT'S of time on G-2 and I'd have to say it's dam close, I only tested the Co-pilot once and it did do it's job...other than that it felt as though I was flying it... I never let go of the sticks or felt the Co-pilot was helping me allot... maybe I'm not doing all the work myself HOWEVER the heli "Felt" like the one's in G-2 and it didn't seem fight me at all... Of course I have no experience with the Co-pilot on fixed wing's so I really have nothing to compare too...the one thing I'm still not very comfortable with is the up close flying... it just seem foreign to me to have something setting 10Ft from me in the air... I never was a "down on the deck" rudder drag/tail touch kinda of pilot.
