Several years back when the X32 and X35 were going head to head for the nextgen lightweight fighter, Kevin Cox designed and built one for 50mm microfan. I lusted after that plane...
A couple years back I tried my hand at one and almost had it flying for the GWS40mm fan with a Feigao bl motor on 3s. The airframe needed to be a little larger as the wing loading on a flat plate airfoil was too small(~100in^2) and too touchy for my reflexes. a few months back I thought about trying again and using a larger airframe (~225in^2) and a 50mm microfan.
This is the thread for my design, build and test flights after which the plans will be available to anyone who wishes to download and build as long as its not for profit.
This is as far as I have gotten with the design to this point. I am involved with another project that is undergoing some changes and until that one is complete I wont do much on this one.
