This is my second generation bi-loop or bi-blade design which, is much more like what the MIT boys pumped out, featuring a more teardrop-y kinda' shape. Much like V3 of my tri-loop design, these ones again follow a more traditional approach to propeller design in general, and the shorter loop edge helps to reduce weight and maybe improve prop response.
Currently available sizes from 4" up to 7", STEP and Fusion 360 files are included (without tech support). Also, the 7" version wouldn't loft properly so it's just a scaled 6" version, sorry.
Watching the video should explain it all, but basically I'm attempting to further develop upon MIT Lincoln Lab's toroidal propeller concept by offering up my design for anyone in the FPV drone community to have a go and see how they like it.
