RE: parkzone planes
I've seen the Mustang fly, it's pretty impressive. The ESC can be jumpered for NiMH or LiPo, and with a LiPo battery the Mustang really hauls.
The FW-190 and the Spitfire are basically the same configurations. The Spitfire is the newest and the lightest weight of the three. That's the one I'd buy if I were in the market.
