RE: 50CC REVOLVER!!
I agree it could use a little more "flash"; IMO the 70 by far has the best scheme of the three...
It would be fairly easy though to cover up some of that white monokote with some better graphics. Are these planes pretty "draggy" for speed? I know I've seen videos of 160mph little Revolvers on 12S electric; never heard much about speed in the 70 size. The 50cc size could be interesting with a piped 50-60cc motor[8D]
