Corsair,

I've got a Sig SE and it is great. You could probably get away with it as your second plane IF YOU SET IT UP RIGHT! This plane has large control surfaces and it is really light. If you set it up on the recommended high rates in the manual it will roll very fast and preform very tight loops. I would not try to fly it this way as your second plane. If you keep the throws low (probably lower than the recommended low rates) you can tame this plane. Either way, it slows to a crawl and you can practically land it at your feet.

Anyway, if you really like the SE I think you can set it up mild enought to make a good second plane. Then, increase the throws as your skills get better and the plane will grow with you.

Good luck!

Carl
