Great Model

"Bought an Orion from Acemodel. It arrived in the post the next day. This model is very well built and the finish is excellent. It only took a few evening to get it ready for flight. I was very impressed with its performance being fast but can fly gentle and slow. It is very stable and can do any aerobatics but if needed it will thermal soar. very happy with my purchase and highly recommended."
