Hello Gene;
It should fly OK at that weight. If you have it benched trimmed pretty close, and initial flights show few problems, start thinking about propellers. That is a key element on airplanes that are a bit on the heavy side. Research what people are using in OS LA.46s and get some samples of each. Once your flight trim is pretty close, start experimenting with the different props. You'll have more than enough power with that engine, you just need to use the right prop and it will make all the difference. I'm gonna guess that 62 feet from handle to center of the fuselage will be a good starting point for line length, and a 5.2 to 5.3 lap time. APC makes an 11.5-4 that works well in the RPM range you will be operating in, say 9500 to 10,000 RPM at take off. Some have been using the APC 12.25-3.75, but you may not need that much prop. Don't be affraid to cut props down, just be careful with having equal blade lengths and with balance. Jim Lee makes a neat tool for marking up props for cutting them down. He's in the vendors section. The model looks good, and if it's straight, trimming will be pretty easy.
Good luck and have fun,
