Jay,

The ESC thing to Jeff Michael was just an FYI, that his Jazz ESC was way under the limits for his Logo 10. The Jazz ESC he has is rated for 40 amps. The Logo 10 and it's motor requires an 80 amp minimum or and 85 amp. Yikes!

Concerning your crazy/glitch problem. With all you have listed. You have one of a couple troubles. Bad motor, bad servo. Now it's a process of elimination. Glitches are one of the hardest to figure out. Your 4 minute flight kinda indicates a bad motor, it doesn't have to over heat to cause harmonic interference. Neither do servos, that's why it's so hard. Take one step at a time, again process of elimination. Even a bad belt can cause interference, what a hobby. Keeps you on your toes. I've been EXTREMELY LUCK, I have never experience glitches. Oooops, yes I have, it was a bad servo.. Servos are notorious for what seems to be glitches. The will pulse and cause the heli to go whack-o. They can over heat too. My beat is the elevator servo, front one.

Let us know, God Bless,
