I am another ex instructor that loved teaching in a Tomahawk. Taught in the rest as well
It won't be noticeable to a student any taxing differences.
They are not the same in the air by a long shot. The Tommy does what the books say. The others have all the nastiness designed out of them.
The T tail as the book says is out the prop wash so its not as effected by power changes as the others.
Loads of room in the front so neither person is encroaching on the other person even if they are 6ft plus rugby players heads won't be banging off the ceiling.
And very good all round view.
