I don't know...perhaps a third plane. The 6xas is a much better radio for the $$. I just sold mine here on RCU. The Sig 4-star is a good choice for a second plane. I know a lot of guys that have gone this route. If you are dead set on the SE tone the throws waaaayyy down. This baby will do snap rolls faster than you can count em'.
The four star is pretty darn forgiving yet is a stable flyer for a first sport low wing.
Best of luck with what ever you decide!
