I had a hard landing which bent a gear leg (bungee style with die springs).
I have been landing at some pretty challenging spots in the Idaho
backcountry while feeling out the short/rough capabilities of the Rebel.
Well I guess I found the edge of the envelope: I put her down on a 700'
rough rocky strip with trees, at 4,000' elevation. I knew I had to plant it
right on the end, and plant it I did. I was already aware of the tendency
of that wing to maintain its rate of decent in the flare regardless of
increasing aoa. I knew I would need to add power to arrest the descent, but
I guess the shortness of the strip influenced my reflexes. Anyway, I hit
pretty hard. I looked it over really good, and then went fishing. Only
after really getting down on the ground and looking carefully, a week
later, did I notice a bent gear leg.
Has anyone had success with trying to straighten one, or will I need to
replace it? I was thinking I could put it in a press with some blocks of
wood and tweak it back into shape. Seems like it will be a pain to
replace..will have to basically take the whole gear assembly apart.
Anyway, I will probably keep flying for the rest of the summer. Some 29"
bushwheels will be on my shopping list if I'm going to do any more strips
like that, and VGs. Will VGs help with the "falling out of the sky"
characteristic? Doesn't seem like the best stol airfoil, maybe that's why
Angus came up with the LE cuff. As someone said ...sto...but not L. Seems
like it needs more flap too. If you look a Twin Otter which I think has
the same airfoil, it has a ton of flap. It still falls out from under you
if you're not carefull though. I have often wondered why Dehav. used that
airfoil, and I guess it can be used to a pilots advantage in precise
touchdown control with no float, but with a plane like the twotter you can
flare it a lot more....and the gear is really, really tough....I know.

BTW, Are you using VGs? My hope is that they soften that last drop in
phase.
