Motor Problems

Well, I think I finally figured out what was wrong with my EZ* (which is currently at 26.5 oz flight weight with 2200mAh). It has been glitching and motor cutting out (along with the whole servos and everything). It was very intermittent and happened for only brief periods of time, but it was getting worse and when it made all the controls go unresponsive, it was very bad. So, I swapped ESC's out to the new Turnigy 40A Sentry ESC I have for putting into my difference. Swapped my Hitec Mini 6s out for the Neutron 6s dual conversion from my Typhoon (which has NOT been having any problems in the same flying area). That "seemed" liked it fixed it (at least no glitches in the quick test flight), but the motor also suddenly quit working too. Glided it in and checked it, and the motor was boiling hot. And the foam around it was melting, so now, it is very loose and sloppy in the mount. Pulled it all out and started looking, and one of the wires had melted through the insulation and it looked like it was shorting out to the case of the motor. It was also very rough on the motor shaft spin, so I put a little 3-in-1 oil in it. Seems a lot better now. On top of all of that, I have been running my prop blade backwards. It was pushing correctly, but I didn't have the right leading edge going the way I needed. Hope that hasn't been contributing to it getting super hot and not doing a super great job pushing (seemed like it should have a little more thrust).

Aerial Video Footage

Got my first aerial video footage with my ATC2K helmet cam from Oregon Scientific. Spent some time and edited the footage down to about half of what was there originally. I need to learn to fly smoother when taking video, because the erratic motion of large control surface movements really makes it tough to watch. It would be cool to find a way to integrate the on screen display with current, heading, GPS, altitude, speed and temp all into this on just the helmet cam, even without transmitting full FPV, but I guess that will have to wait.

I'm still having problems with the glitches, and I'm wondering if it is the BEC on the ESC not able to handle the current (it is only rated at 2A at 5v). I have a new 40A ESC that I'm going to use for my new out runner motor on my Typhoon, but not using right now that I may put on (it has 3A capability). If that doesn't fix it, then I'll have to start swapping out the receiver and stuff. I'm going to try it one component at a time.
