you can go to http://www.towerhobbies.com and they have a great selection of good planes that would be great as a second plane. I would definitely second the choice of a big stik as a great second plane, as well as a good windy day plane as well. You'll hear alot of recommendations for the sig four stars, goldberg tiger II, and any of the sig kadet lines...... another choice to consider is the great planes Super Sport. On low rates, this plane can be flown nice and slow, but step up to high rates, and you've got a great aerobatic performer.

Just a thought..........
