Looking for something to power my jato/pede Novak 5.5/6.5 or 5800?

To be absolutely perfectly honest with you there's that many motors around that 30 people could recommend to you the "ideal" motors which are completely different, and they'd all be right.

In theory, the 380C 6L should get more runtime because the smaller rotor, takes less energy to turn, but the side effect of this is a drop in torque compared to a larger rotor. But being a lower wind it may make up for this, and revs slightly higher than the 540 8s. Its all swings and roundabouts, my personal preference is neither of them..my 540 6s (actually I have two, one Feigao branded, one Mtroniks branded) serves me well. But out of the two I would probably go for the 380C-6L.

Its not really that hard to find the sweet spot on gearing..all it takes is a bit of time, what most people I know do is just pick the top speed they want and gear accordingly for that, as long as it doesn't overheat anything it seems to work well as a starting point.

And just to help confuse you with the gearing a bit..to a point, a 540 will accelerate faster with higher gearing, because the time it takes to spool up anyway.

So at the end of the day I'd go for the 380C-6L over the 8s. With my setup (540 6s) I can dump a battery in 3-4 mins if I want to, so I wouldn't recommend it to you, although it may be more powerful than either of the other motors.
