RE: Help me pick my next kit - I can't decide !
First warbird at the .60-.90 size I would recommend the p-47 in the top-flite series. Big wing, some dihedral awsome looking, lots of scale stuff you can do (sliding canopy, cock-pit, radial engine, bombs/tanks). Kits as a P-47D<25 Razorback or optional +25 Series Bubble top. Minor modifications to the wing tips and dorsal fin you can build Ms or Ns as well. Lots of cool color schemes.
Skyshark also makes a great 60 size kits, they call for .60-.75 2 Stroke but will take the G-90 fine!
