Electrolight,

A trainer is pretty much a "trainer". Doesnt matter what brand or type it is. They are all pretty much the same (if you look at different brands and models). The huge wingspan will be good for you because it keeps the plane more stable in the air. Ive flown about 5 different trainers in the past and I can honestly say..they are all pretty much the same. Only difference is, some are a hassle to build and some come together very nicely. I heard the Tower Hobbies trainer isnt a bad choice. Should be no worries with that one.

Good luck on the build and spend some time on the Simulator will defiently build up your cofidence.
