Earlier comments seem quite appropriate to me.
The back seat of the KR-03a is MUCH more comfortable and has far better visibility than the 2-33.
There's a 5000 hour life limit on the KR-03a "Puchatek". As far as I know this has yet to be addressed. It is a while since I have spoken with Barry Aviation, since my club sold their last Puchatek. At one point Barry were considering accepting trade-in of your KR-03a against a new Peregrine...
If the Peregrine exists.
The 2-33 does not have any paperwork for installing electric thingies (battery, COM radio, computer, FLARM, TXP, logger...) Believe Puchateks do allow such things.
Kr-03a even has a rear instrument panel.
The "Puke Attack" is a good winch trainer. The 2-33's "CG hook" is too far forward to be practical.
The nose wheel KR-03a still had rubbish for wheel brakes.
The Puchatek is easier to transition people to "glass" from.
Uli he's kidding, I'm sure. But let's pretend it's summer and not restart that recurring thread.
