RE: SIG Kavalier
The Kavalier is a very good model and one I recommend as a secondary trainer. But you didn't build your first trainer, so that puts you at somewhat of a disadvantage with this kit.
If you're willing to take your time and make sure it's straight you'll love the Kavalier. I'm personally willing to help you with any trouble you may have while building it - at least as much as I can via e-mail. If you have questions just shoot me an e-mail.
Another good secondary trainer is just about any decent Stik model. I also highly recommend the Sig Somethin' Extra or Mid Star as well.
Even these models can be good performers, all you need to do is put on a lower pitch prop to keep the top speed down and use less control throw until you get comfortable with the planes. That will make them easier to transition into and still allow you to progress when you're ready by increasing the throws.
