Co-runner video

Roy, I do not think the two motors + two gearboxes system is very complicated. And like I have explained earlier, I think the geared solution has some benefits on it's own. Like being able to swing a much bigger prop for the same weight as an direct drive outrunner, which in turn gives you better braking. But there are many ways of building a coaxial.

If you like simple solutions, here's a video of our "co-runner" system (thanks for the name aerolite). It does not get much simpler than this:
F3P Coaxial "co-runner" prototype (3 min 31 sec)


The system on the video is the first prototype. Since that we have built 2 more, but a bit lighter ones.
