Its a tad nose heavy with the 120, about 1oz lead brought it right online with a Sullivan tailwheel and 2/56 rod tail braces. The Sullivan TW replaced the one I lost in flight, most likely due to my own fault with installation. I would have thought the 120 would make it much more nose heavy than it did, a pleasant surprise when it came as close as 1oz. AUW, dry, is 8lbs. 14oz.. You can get an idea of performance from reading my other posts. AWESOME!
