Went out and flew the C&D timer today. Sometimes it went well and other times it was frustrating. I believe the frustration was caused by the Jeti Spin Pro 44 ESC that I'm using. The first flight the system armed and gave me a beep. Then I got the momentary spin after 3 seconds. After the delay time was up the motor started to spool up then shut off! This happened several times. Back to the pits. After fiddling with the ESC settings ( I don't remember what I changed) the motor would stay running. I flew a couple of 2 minute flights to set the lap speed. Then programmed the timer for a full flight. The next flight went well. I then adjusted the Climb and Dive settings to see how I liked it. The next flight the motor started and then shut down again. I disconnected the battery and connected it and then the motor stayed running. All is well for the next several flights. Then on full flight 4 I stated to run out of battery in the OH8. After I landed, I checked each cell and they were all about 3.5V each. This is what they normally show after a good flight. Back into the ESC program and I noticed that it was set for the Glider Outrunner setting and when I checked the manual settings the minimum cell voltage was set to 3.2V. I'm running a Li-ion pack and this setting needs to be 2.7V. I changed it along with the cell count from Auto to 6 cells. The next flight went well. However I was not getting the momentary spin up of the prop when activated. Time to go home.
On the bench tonight I tried many combinations of ESC settings and I still cannot get the momentary spin up when activated. The LED goes from GREEN to a momentary RED, then to BLUE, and then the flashing LED till start up. Why don't I get the momentary spin up?
