Low headspeed 130x

And a poorly done video of v2!

Low headspeed 130x - v2 (1 min 16 sec)

That is pretty neat. It would make a super easy trainer for basic orientations. You'd really have to give it a positive pop first but I'm sure it would fly inverted just fine. Might wag if you fly hard but I doubt that is what this build is about.

Tonight's discovery is that the Lynx main frame has enough motor adjustment to use the Red Bull main gear (122t by my count), with a 9t pinion.

In fact mesh is perfect, no hassle. Lower gearing has enabled a lower head speed! Now getting about 1600rpm at 50% throttle. Going to dig out the 8t pinion I bought a while back to try it out.

Hey Giiba,

Nice work!

I'm toying with the idea of a 150 size frankenheli build and wanted to know where you're sourcing your Lynx BL motors from.

Thanks, and keep up the great work!

Phil.
