Scale and as a starter jet to suit P-60 or P-80, and other 12-20 lb thrust turbines. I would highly recommend easy to see 'not to quick' jets with forgiving flight characteristics. There are others no doubt but these ones spring to mind for me as being classic examples and very popular being available from a variety of manufacturers and with many colour choice options also -

L-39
F9F Panther
T-33
MB-339
F-86
Mig-15
F-15
