The spad cap has turned out to be one of my fav fliers now. 80+ flights and a few crashes.
Crashed sometime back, leaving the spar sheared, since then changed the spar clamping mechanism. Some other changes/repairs made as well:
1. Now using Jubilee clamps to clamp spar in between, the clamps give in to metal fatigue easily so I just loosen them and pull the spar out from both sides. Some repairs on left wing.
2. Slipped plastic nut bolts from my little one's mechanix kit to hold the wing in place
. These things are great. I wish hobby shops stocked these.
3. The angle of incidence was fixed. Started with about 4 degree, would go vertical despite major downthrust, and tendency to stall as if tail heavy, reduced to 0 deg.
4. DIY hatch locks for coro, and lots of hotglue repairs
