This is the stuff for your De Havilland, right? Sounds like you're in business.
The Rascal is virtually finished. Just a couple of things to tidy up. All up weight is 24 oz. (with a 450 power system). It's the same set-up I used in the other Rascal. Full throttle is not used! But flight times are ridiculously long, up to 30 minutes.
