Nice Flying. I sold my first Multiplex Tucan that had a 3S Setup. I'm working on a new one with a 5S Setup and 42mm Motor so I can safely experiment with different props. I'll probably start with a 13X10.
In my experience, the Nexus phones don't do as well on CDMA Networks battery wise. The introduction of Sprints Spotty LTE made it worse. The Galaxy phones on the other hand are tested by Samsung and Sprint before release and Samsung deploys their own proprietary power management features.
With that said, Will be trying T-Mobiles Nexus 6 (Which is the closest to the Motorola/Google play version). If I can't get more than the 3.5 hours of screen time I get with the Nexus 5, I can always send it back.
I need to replace my Bearings also. I have seen high quality bearings for $70 and standard looking ones like what is seen in your video for $20 per kit. The $70 bearing kits are rated for 8000RPM which may be overkill for my 1300RPM washer. Do you think most bearings that can be found on Amazon or eBay are better than stock Bearing quality? I just don't want the bearings to fail again another 2 years down the road.
