RE: ARF or RTF to get the rust off.
Sig Rascal 40 ARF, a 72" w.s. sweet flyer that you won't regret keeping in your hanger. If you want a slower floater go for a Sig Kadet Sr. ARF, 81" w.s. big and EZ to see. It' size makes it loveable even after your through with trainers; candy drops, slow fly it backwards on a windy day, etc. The new just released ARF's have gotten a little pricey (haven't they all) but are still worth it. I think the new Rascal now has flaps too, not sure.
