First of all I want to thank everyone that owns and has built this plane. I just finished my Harmon Rocket after many mods that have been mentioned on this thread. I used one elevator servo tossed the the stock tail feathers and made them out of solid balsa. strengthen the landing gear by installing 1/4 carbon fiber braces. added 14 oz fuel l tank Its powered by a rossi 65 with tuned pipe turning a 12x 7 prop on the ground engine is spinning at 14,600 rpm. the Cg is at 3.5 just a little nose heavy. Maiden the plane over the weekend and at first was reluctant to fly it because of alot of horror experiences that alot of people had one there first flight not to mentioned that it was a little windy. The plane took off without any trouble and the rossi got the plane going roughly 130 mph chasing a warbird with a ys110 while we were triming it. Once trimed the plane flew very well and fast im very happy with it. it was stable at high and low speeds turns on a dime and rolls very quickley After about 10 minutes of flight it was time to land and had no idea what to expect. brouight the close to the run way shut down the throttle and let it come down on its own and landed without any trouble. During the build and seeing what had to be done with all the mods and attention this plane needed I wasnt sure if all the trouble would be worth while. All I can say this i am very happy with the plane it looks great in the air flys great. Later I will put picks on the forum
