DON'T put a zenoah on it if you want it to fly well. The more I fly, the more I see what a HUGE difference a light airplane makes. The GT-80 is WICKED heavy!!! The ZDZ-80 appears to be the perfect match for the hanger 9 planes. It is VERY light and produces substantially more thrust that a GT-80, plus it runs very smooth... very well balanced. Your wings will thank you and you'll be rewarded with a terrific flying airplane.
