For all this following the evolution of toothpick style FPV quads this is my latest work in progress. At the moment it's quite unclear if the concept of a 5 inch toothpick will work out but Kabab FPV, Alexandre Arvinte and me are working on the topic of props, motors etc. If you want to join im, here is the frame you need! ;-)
Please watch the Youtube video to get all the details on this frame.
