RE: Which second plane
I dont think it would be to much on (very) low rates. BUT, before you try to solo it wouldnt be a bad idea to have an experienced pilot take off for you so you can get a feel for the plane while its (high) in the air. Wouldn't hurt to do this a couple of times. Thats what I did on the Extra, it was my second powerd plane and its still in one piece... knock on balsa.

However I do highly recomend the Zagi, nothing beats it on the scale of indestructable....
