The Astro-Hog is not a good second airplane...Not a great second kit either!

They get a little snappy when they're slow and just aren't as forgiving as most "2nd airplanes".

The LT-25 is not much of a step up from ANY trainer, but is a great airplane. I love SIG kits and the LT-25 is one of the best...There is no reason not to start building the Astro-Hog now, but don't get in a hurry to fly it! Once you get there, it is a GREAT sport flyer.

runner5, I would recommend the Sig Fourstar...
