Yes, need to come up with something better.

Yes. A proper throttle quad could be another project for next winter.

That's about what I have found. Did not need to re-trim. Only set up
for the new speed. Just seemed interesting that those tiny flaps
acted more like adding full flaps on an old big-bar, manual C-150
rather than, say, an old manual Cherokee.

If I can get the throttle creep problem resolved I may very well find
that to be.

That's sort of what I have been trying to do. Get the tail down
without excessive pitch angle so that the last bit of drop isn't so
bad. But you are right, If you nail the tail down first, it won't go
flying again. But if the drop of the main is more than a few inches
the resulting bounce off the main wheel will point you in any
direction except straight down the runway. Then things get way too
interesting. Yes, much more forgiving on grass than hard, but since
I'll be flying off the 6000 x 200 foot strip of concrete here at KDTO,
I need to get this down pat.
