I had one last summer and GAVE it away after 12 flights. The guy I gave it to changed a bunch of stuff and said it was acceptable after that. I just lost patience with it. The stab incidence was way off ( he changed it ) the top alumin. wing jointer worn almost thru in 12 flights ( he fixed that ). The covering was very poorly done and kept coming off. The plywood was so weak in the firewall I distorted it by tightening up the engine mount ( I fixed that ). It came out at 17.5 lbs. ( Taurus TS 52 ) which I felt was too heavy espesecially with the added drag of the 2 wings. It flew so poorly ( mostly because of the stab incidence ) that when I arrived at the field I lost interest in even putting together ( another pain in the ***).

Other that that it was fine Some guys love them I guess but you asked for opinions and that was mine

From what I have read on RCU if I wanted another ( maybe ) I would go for the GP Ultimate.
