Whilst I accept the part about the PA 38 tail flexing on recovery sometimes, the main problem with the Tomahawk is its tendency to Flat Spin if the C of G is not far enough forward.
If you do spin it, (and I personally think that spin recovery should be fully taught), then watch for the nose pitching up towards the horizon during the spin.
There are several fatal examples of this in the U.S. and there are not a lot of instructors out there who will spin one intentionally.
If it happens, you can (if you are lucky and have the height!!), loosen your shoulder straps and pull yourselves towards the panel to move the C of G forward. This might sound drastic but I know this from experience, I was a pupil not an instructor then. I also know this has happened to others.
The tomahawk that we know now is not the same A/C as was tested by the FAA. It has four less wing spars and the tail construction is different.
Other than that it is a nice aeroplane to learn to fly in as you have to fly it. Cessnas fly themselves.
