thank you for your time
Right now, I'm running the 2805/1600 on 2S 750 on a 16 incher that survived indoor and it's a bit porky, since for indoor I was using a 16g motor on 2S 350s. But, it's fun to fly. I'm thinking of going to 20" on my next outdoor version, with a fuse length of 22". That would give you 2.76 square feet of wing area and even at a flying weigh of 10 ounces, you'd have a wing loading of only 3.6 ounces per square foot. If your wattmeter says 60 watts or more, you'll have a winner.
Should mention............I cut the airfoil template from 3mm Depron using a steel ruler as a flexible French curve.
