Steve I agree if I went with the non Air Chambered it would have less parts. What is the air chamber on the back, if they all use the crank for "supercharging"?
I think I'll use the YS for the Corsair because we had to add 3 oz of weight to my brothers just to balance it with the OS 120 fs!!! That way I can use the Saito in the Ultimate and maybe mount the servos in the back.

Cam, on a side note, I have a friend with two Camero SS. One is a '69 and one is a bit older...I love them, they are both stock but one is under a tree in bad shape...NO, SHE DOESN'T WANT TO GET RID OF THEM hehehe. Anyway, I fly mostly warbirds with big engines so I am use to flying at low throttle most of the time for scale looks so it doesn't bother me. My pet peeve is adding balast when you don't have to. But isn't it nice when someone jumps on the field without telling you and all of the sudden he's taking off and you can just pull up and go vertical, man, that just gives me goose bumps . Besides, I want something I can "wring out" and not fly scale all the time.

Thanks guys, I'll try some post about the paint issue in some other fuorums . If someone has some inverted engine installations I would like to see them.
