Yes, been holding full up elevator on the takoff roll as long as possible...of course, part of the issue is you can't do that for long, since with the flaps down and NACA strips, the hing wants to jump off the ground WAY too early. Granted, it's flying, but barely...and teaching the student that habit will surely result in a stall later, when flying aids are removed.
Been flying nothing BUT taildraggers since the beginning, and this one is SIGNIFICANTLY worse than most. It's also a good bit worse, ime, than any other warbird I've flown (including 2 different mustangs, and a T6)
The real "shame" of this so far is that, beyond places like this (most of which suggest the same things we're talking about here) there's no real help from horizon...any information from them that mentions the ground handling of the PTS Mustang simply talks about how "superb" it is.
Ahh well...we'll keep arguing with it. I'm hoping a larger, gripier tail wheel will offer a bit less slippage of the back end.
