I put ailerons about 20" long on my Easy star. I used HS55 servos but it still needs rudder input. I also bent some 3/32" music wire and 1 1/4" foamies for landing gear. It will ROG even on fairly heavy grass even with the stock set up until the battery is about half depleted and any time from a hard surface. I started off with a 15C 3s 2100 electrifly battery and the motor ran well but only lasted about 15 flights. I then mounted a Rimfire 28 30 950 with a Electrifly 25 SS speed controller with an APC 9x3.8 slow fly prop and it flies very well. It runs about 74 watts on the bench and I regularly get 30 minute flights with varied throttle. I just purchased a 30c 3s 2800 and it now bench runs at 99 watts so I know it will pep it up [sm=wink_smile.gif] but i have yet to fly with the new battery. This bird flies very well and is very sturdy. I would recommend it to any pilot novice or advanced. It's great to get it down on the deck WOT and see how close you can get the wing tip in a bank and when it happens to clip the ground you just give it a ground check and get back in the air. I also added nav lights a strobe on the bottom and switched landing lights all LED and fly it at night.
You can batter this plane and with a dab of CA your in the air again. I've hit trees, fence posts, clipped the wings on the ground numerous times and had three mid-air collisions (combat) with mine and its still airborne.
