I just finished mine, built it from plans, it was an easy build once all of the parts are cut out which DID take some time. I will be flying it soon. It weighs 13 lbs with retracts, flaps and rudder servos ( the original didn't have operating rudders as in the EU they are not needed!) The designer now has an upgraded model with a longer fuse, thrust vectoring, canards and a smoke system he is looking for another magazine to publish all of this in.
