The main control you'd have to use on your trainer box to prevent my mishaps is the "judgment" switch.  Yesterday's mishap flowed from my decision to take off again as the (already safely landed) airplane veered toward the edge of the runway.

Instead of doing the sensible thing and "staying with it" to keep it on the runway, and accepting the possibility of the benign "nose-over" in the rough, I cobbed the throttle and applied up elevator.

As my poor technique would have it (notice, I didn't say "as luck would have it"), it appears that the main gear caught in the grass on the way up.  Barely airborne, the airplane pitched over and BAFFED into the sod.

It's fixable, mostly having ripped out the main landing gear, its substructure, the windshield, and leaving various bits of toothpicks both inside and out.

My goal has always been to put this Cub on floats, so needless to say this is provides a prime opportunity to reconfigure it for floats or for a convertible setup for floats/wheels.

None of this is to suggest that I think flying the Cub off the water will improve my judgment!
