I love my Sig LT-40. It was a great build (mine was a kit) and is such a gentle flier. With that big 70" wing and extremely light wing loading you won't believe how that thing floats!

The biggest mistake I made with my plane was putting the O.S. 46LA engine in it. That 60 size wing and fuselage generate a lot of drag, and the 46LA doesn't provide much power to spare. It'll cruise around the sky flying pattern, and will loop if I give it a bit of a diving start, but there's not much power to spare beyond that. With this engine it's a great trainer (it's so slow and gentle, a real ***** cat) but without a bit of extra power there I'm outgrowing it faster than I thought I would.

Having said that, I've got an O.S. 61fx sitting on my workbench which WAS waiting for my next kit (undecided at the moment... either a Sig 4*60 or a Goldberg Tiger 60.) That engine's just calling to me at the moment, and I DID build the LT-40 with a lot of extra reinforcement on the firewall and the wing
