RE: 2.4 Gasser
You could get a GS TF P-51 ARF, kit, or ARC. You could also get a World Models Zero 80". The soon-to-be-release P40 Warhawk from Skyshark, a BT Spitfire if you are able to build from plans...
These are all planes I am considering for my own Brison 2.4 -- by all accounts the WM Zero seems to be a really great (easy) flier.
