And in the meantime I flew mine at almost dark with the Super Tiger 45 and an APC 11X5. ABSOLUTELY NO PROBLEMS AT ALL! I've been in this hobby 30+ years and it frosts my backside that so many people think "4 STROKE IS BETTER" in all cases. 4 Stroke is an option, not a prequisite. So people it boils down to 2 things. A plane the says "3D" doesn't always mean you HAVE to fly it as a 3D plane. Not "everyone" HAS to "hover" do "Harriers" and what not. Planes were flying LONG before these things were "invented". KUDOS to you for the Webra 50!!!!!! It goes to show you that all that glitters ain't gold and all that swings a prop ain't 4 stroke! So bottom line the Funtana 50 WILL fly superbly on a 2 stroke, and as good as mine flew, I have no intentions to adjust valves or set timing!
