RE: goldberg obsession 3-d??
Well I bought one (6 months ago) , and got it together last weekend...GMS 1.20 2-stroke off of E-Bay, looks like a real low time motor, I left the factory tank mounted over the wing center section, but the needles were a little sensitive to the long distance fuel draw (no pump), so I moved the tank up behing the firewall, the original tank is too thick to squeeze into the area, so I picked up a DuBro 20 oz. Fit perfectly. Fuel draw is good, 16x6 APC and after experimenting with several props a 3 Dead Stick landings...she is a real floater but comes in a little fast when deadstick. My fourth flight today was perfect, landed like a butterfly with sore feet. Tracks nice, reminds me of old pattern plans from the 70's just bigger. She has a really long fuse, that tracks like an F3A bird. I am not into 3D that much, but it is a great buy at $249.00. Mine has Harley-Davidson Custom made graphics on it, so it looks a little different. Fun plane!!!
