Hi It was one that we did at GPA Hobbies as a group. The plane flys very well but does need some TLC from you as a builder. The first thing is the plane comes out tail heavy or at least ours did. we put a 1500 mah battery in the nose for the ecu. That did the trick for balance. The plane is a great transition plane as it has both the DF and Turbine tail pipes. I understand that the future versions which will be here soon have all of the upgrades that we and other people have done in the planes. We have a RAM 500 for power and it is plenty of thrust, I have heard of some people with Jetcat80 and Ram 750's in them but why carry the extra weight? I wasn't present for the test flight but the guy who flew it had such a good flight going that he flew until it was dry and did a dead stick landing with no problems. We have a few avaible in the next shipment if anyone is interested.
