Thanks Dave, I couldn't remember the T-52 site but now have it on favorites.
A friend built one with a shorter 48" span plus ailerons. He's an expert pilot so he hasn't tested the EPP foam as fas as crashing.
The wings, Zagi or FMA Razor are far from a trainer. They will stall very easily and fall out like a willow leaf. Not bad as second or third planes though.
