RE: warbird
If you are looking for a park flyer then stick to the Parkzone Warbirds. The best is the Spitfire. It has three wire zervo's and uses the zx-10 system ( same crappy style transmitter though) You can easily upgrade with receiver, Brushed ESC, and 11.1v lipo battery.
Parkzone also has the Folke Wulf, and the P51D mustang.
All are great and easy to fix.
RPMROB's corsair is nice but very fragile.
Goodluck
