RE: prop rpm question??
Yes sir, I do. It will hover and also will pull out but the pull-out is sooo sloooow that most times I just rock it over and fly it out. Don't get me wrong, the old 91 has treated me well and it's still strong considering it's 11 or 12 yrs old but the 260 is roughly 6.5 lbs and that's just a wee bit much for a 91 to hover. The 100 at only 1 more oz would be a better choice if one is buying an engine for this plane. If you already have the 91 like I did it will get the job done but that's about it. I know one fellow in my neck of the woods that runs a Saito 125 on his and likes it a bunch. I think the 125 is only like 2 or 3 oz heavier but I don't know that for sure. Good luck with yours.
