rcken will be doing a review on the student trainer pretty soon once he has caught up on his job. The beauty of the student trainer is the kit incorporates as many different types of building as they could all in one plane so the student builder has an idea of most types of building when they move on. BUSA always runs a lot of flight testing before they put out any new product so not to worry about how well it flies.
The Krafty is a Joe Bridi design and is a step above most other trainers and would be my first choice but everything you have mentioned or that others have mentioned are also very good planes. Not the Cubs of course. The Tiger is an outstanding plane but not quite as easy to fly as a true trainer, usually they are a new pilots second plane but it's a choice thing and up to you.
The Krafty will do it all too.
I find trainers are about as much fun as you can have on a nice windy day. I have never mentioned wind to a student and take them out when it's blowing very hard so they aren't afraid to fly in the wind. I had one older student that was flying very well in all wind conditions until one day someone started talking about it and several years later this old student is still afraid of the wind. There is a point when flying in the wind becomes work instead of fun though but you can still fly in it.
It's been a long time sense I have flown the Krafty but I think it is everything you are looking for in a trainer. And looking at Johns trainers and what he has done with them shows you they have no limits. I would love to get the control of the sticks on all of them!!!
