The reviews in Shockie's post #3 are intriguing. I could not get the balance point correctly no matter how far forward I put the batteries. There are several threads on TRF for this model. I have posted on some them. If you are like me, it might be awhile before you build this model. Let us know when you fly it and your experience. I finally threw my original model away, and, lo and behold, I inherited the model again from an estate. This second model was probably assembled better than mine. It flew last May at a club NAR section meet. It was really fun on an E12-4 with a clear blue sky and no wind. Went up straight and high with lots of fire, noise, and smoke. I was getting a decent glide and then the wing broke just before touching down for a DQ flight. Luckily, the detachment was easy to fix and it is ready to fly again. There is a lot of sanding on the wing and the wing flap joint is tricky. Flies great on an E12 with a clear blue sky. I would be glad to try it again.
