What were the improvements that the Focus 2 had over the Focus 1? I am considering purchasing an Focus 1 or 2 for practice and eventially sportsman class.

Would a YS 140 Sport pull either of them well for sportsman? I've noticed an intersting thread using a gas motor on an Imapct, any thoughts on this using a Focus?

Can either of them balance with rear mounted elevator servos?

Thanks,
Mitch
