I have been looking around the extra market and bought a Great Planes extra 300s 60 size and at 109.00 bucks for the kit it wasnt bad. I'm ganna put a 12 oz tank pull pull on the rudder and twin elevator servos on the tail to balance it out without lead(lead is my worst enemy when trying to hover....wieght) I'm definitly enlarging the rudder by at least 1.5 inches. Looking for a nose up knife edge..... I am going to put a Ys 1.10 Fz in teh nose for some power. I mainly want to know is this to much or too little. Its a good engine and can make these .60 size planes hover and shoot up out of em. If anyone has any tips or anything to make this plane a wicked bad to the bone extra. Tell me. If anyone knows of anybad habits about it, anything, i want to know now before its in the air and to late. Anything at all will help. I havent bought the engine yet so if there's a better engine let me know. This plane is ganna be my first True Aerobatic(excluding profiles-kinda aerobatic ~{but only a 46 size and was no pull pull, old kit}.......ultra sports.....low wings) Eventually I want to enlarge all surfaces too.
