Ian,

My latest pupil is using a Seagull Boomerang which I assembled for him (after we pulled the wings off his first trainer, not enough glue at the root, he learned that one the hard way).

An excellent aeroplane, kit goes together well and quickly and it flies like a dream. Has semi symmetrical wings so can do aerobatics for advanced training.

Once I had test flown it I didn't want to hand it over to it's new owner, can't say more than that.

One piece of advise if putting together any nose wheel trainer with steerable front wheel, keep the degree of movement very small.

Simon.
