Re: Proxxon Mill CNC Conversion

Thanks, the RC helicopter you refer to is the pixel by Alexander Van
De Rostyne, beleive it or not he has gone one better with the
pixelito, this weighs only 6.9g. I know Alexander and have often
considered building a copy but I can't really fly helicopters so it
might not be such a good idea.

not much larger than a coffee cup that was R/C controlled. Did you
build that one too?
