Here is how I see this.

In the other thread that was locked, it was asked if the Stik could be a trainer plane and it was beaten to death on the pro's and con's of doing it both ways.

This thread seems to be more to the point of asking what flight characteristics can be expected.

I will attempt to answer it as such based of the flight experience of the creator of this thread based on items the creator of the thread has given to me for review

A trainer will attempt to recover to upright flight from a turn or inverted due to dehidral. A dive and climb are not effected

A Stik will keep flying in whatever attitude it is in. Basically what is called a point and fly plane.

A trainer has trouble in winds over a certain speed and crosswinds can be tricky and turning downwind to crosswind my try to flip the trainer onto it's back

A Stik slices better through wind around 60 size and bigger but a smaller Stik can be tossed around pretty good in the air to the point of turning downwind to crosswind and having it flip over on it's back.

Both the trainer and Stik can be slowed to a crawl for landing

The trainer will take more abuse than most Stik's will. A good example in landings that bunny hop down the runway or simply planting it onto the ruway. Trainers will take a good amount of this. Stik's will loose the landing gear quicker hence they will not take as much unless the gear is properly beefed up.

Stik's are way more aerobatic the most trainers. Stik's need to be flown with proper throttle management especially when somewhat overpowered. There is no takeoff at full throttle and leave it there. Throttle management in level flight, up and down lines is important. You have bigger control surfaces and if control geometry is not maintained then speed and the flutter that comes with speed will destroy the Stik in a matter of seconds. Trainers can take a little more speed since it's smaller surfaces and more drag hence less speed.

THere is more but I need to head out for now...so someone else can add to this
