Why not scale profiles for combat?
I would like to build a .15 or .25 combat model but it seems like a lot of effort to build a full-fuselage when it would be much easier to build a profile that would give the same look in the air.
Back in the early '50's Sterling Models sold a zillion C/L P-51 Mustangs and Yak-15's because they were quick to build and you could throw another one together quickly in the event of a mid-air.
Combat models can have a short life so it seems to me a lot more people would be interested if the models were easier to build.
I just bought a new OS .25 FX, just in case I really get interested.
