the zenoahs are really heavy. like you, im around your age and i would seriously listen to these people. I have a Zenoah in my plane, but its "too much engine" for the plane, and thats the only reason it will hover and do all that. Power to Weight ratio is all what hoverings about, and the DA 100 is a very good choice. With the GT80, youll be "trying to get thru the hover" with the 100, you can make it look nice. by the way, youre going from a model tech magic to 33%?
