• XNova 2206 2000kv

Thanks to a buddy who was swapping some equipment on a quad, I was able to snag this one for testing.  The Xnovas have a reputation for good performance and solid build, so this was a fun one to test.  

The XNova 2204(4.6) 2300kv did quite well on my tests, so I was excited to test this one as well.  It's important to note that this was a used motor, so it wasn't in perfect condition.  There was some vertical play in the shaft that resulted in some fairly significant vibrations at 100% throttle.  That shouldn't impact the results though, just my impressions on quality are coming from a motor with quite a bit of use.  The machining quality is fantastic, and even used it still looks good.  The windings look good, and the bearings are not bad again given the used nature of the motor.  Interestingly enough the stators in this one actually do measure at 6mm.  After the extra height in the 2204(4.6) I was thinking this one would probably have some extra height as well, but that isn't the case.  The biggest downfall seems to be the weight here.  At 35g that puts it in the weight class with the true 2207 motors, which makes it a bit out-classed in terms of power in it's weight class.

Results

Again, I was hoping for a bit more out of the numbers on this motor, but at only 2000kv, it is definitely geared more towards efficiency than power.  That shows in the numbers.  Really 5" props are totally underpropped for this motor.  6" starts to load it up.  I think it would probably do well even on props heavier than what I have for testing.  A 6x4.5x3 would probably be great on this one.  The fact that it was able to push the DAL 5x4.5x3 square bullnose prop as hard as it did speaks volume.  Pretty much every other motor I've run that prop on struggled with it.  It still drew 30A for a limited amount of thrust, but that is more a failing of the prop than the motor. The square-top bullnose is just wildly inefficient.  Also the fact that the numbers between the 6x4 and 6x4.5 were as close as they were also speaks volumes.  Under static load the increased loading of the 6x4.5 usually makes it fall behind by quite a bit.  This motor is solidly built and is quite efficeint, but the weight again comes as a trade-off, so the decision is again up to the purchaser as to whether it is worth it for their particular flying style and priorities.
