A Big P-51 like Top Flites' ARF, or a C-130 like the ASM at Hobby People. Theirs is 100", yours could be 100" to 120", a B-17 say at the same size would be nice as well. Any Twin or Quad engine WW II fighter would be nice, or the Civilian DC-3, C-54, or a 4-engine DC-4 or Super Constellation should sell very well...!!!
