Fred...

Each wing is 2.5 x 8, for 20 sq in. The prop is 4", limited by the skid length in parked attitude, and hook to hook is 7.5. If the limit is prop bearing to tailhook, then it's more like 8.2.
Once we got it down from the light and repaired the minimal damage (broken cabane strut) it took several more flights to arrive at a happy medium between being able to ROG, but staying away from the ceiling. What it really wants, at that site anyway, is .050 or .040 rubber. Once we get to Lakeland I can go back to .061.
If I took it to USIC, would there be a space to fool around with it without risking harm to the real indoor jobs? I'm also thinking about an Ultrafilm covered lightweight version. I've never attempted a built-up prop, but it might go well on something like that. Totally experimental.
