Had an unexpected warm day Wednesday, so I snuck off from wifey's required home remodelling project to get in a few test flights on the new LittleAxe.
As a reminder, this weighs in at 10 oz.; older versions were closer to 15 oz. It made all the difference! Norvel .061 is plenty of power with 15% fuel, APC 6x2 prop, 48' lines, around 4.5 sec. laps, give or take a few 10ths. Upwind wingover entry done with ease, although overheads were kinda light on the lines. Didn't get to try moving leadouts forward, as often recommended, yet. Line pull at lower levels is substantial, I can afford to lose some there. I want to try more tipweight too, no wing droop or hinging detected.
No time to play with other props or line length, etc. yet. But it meets all my hopes and expectations so far! good flat stable level flight, smooth round maneuvers big or small as you prefer, sharp square corners with no bobbles, no bogging in consecutive maneuvers. Landings included full-lap glides before touchdown.
I'm really happy with it; I think it's a winner! Much more extensive testing planned in the Spring of course, but that'll just be fine-tuning. Don't think I can improve it any more. So I guess I'm pronouncing it "done", no more "mucking about", Frank! Only thing now is to get the plans into a form usable by others, which still may take a little time what with doing other kits and of course that LR remodel I'm supposed to be working on.
Reminder of vital statistics: 36" span, 200 s. i. area, full flaps, inverted engine mount, uniflow clunk tank, tip weight box, adjustable leadouts, wiggly rudder.
A long time coming but worth the effort, I think.
