It's a great kit and I am planning on buying another one. Get the retracts for it and a good engine. I had a YS .60 on my last one with a tuned pipe. It flies fantastically yet slows down to a gentle float for landing. I put flaps on my last one. mostly for fun, I don't think they did a lot. I aslo ran some navigation lights and landing lights just for fun. I suggest you buy one and have a lot of fun with it.
