This is a few months old but found it checking for Gentle Lady posts. I am a 25-46 size glow flyer but I had this Gentle Lady in the closet that I built back in 1985. FINALLY decided to try it for the first time (long story about the 23 year wait) yesterday when wind was under 5 MPH. I have a Golden Bee mounted to the front and it flew and climbed great. Today the wind was 10 MPH but decided to try it anyway. Didn't have the forward speed like yesterday but still climbed right out. Yes, electric is probably better but when you don't have all the chargers and the Gentle Lady is a change of pace airplane, the .049 is a lot simpler. Funny thing is that the engine was running and the plane was about 300 feet away when another flier cranked up his DA-150 next to me. I could still hear that .049 whinning away. Now if I could just get the Gentle Lady to snap roll like my Kaos.
