Here is my setup.
- Rimfire .32 motor
- Turnigy AE-80A ESC
- Zippy 5000mah 4s Battery
- Swinging a 12x6 prop
I have tried just about everything I can think of.
- Multiple prop sizes (down to 10x6)
- Changing the timing to all settings
- Voltage cutoff settings
- Break settings
- a 2200mah 3s battery
The only major difference that I can see from changing these things is in the timing. Higher gives me a touch more power before it quits.
I have a youtube video of my motor going through a run up that I will post if that will help.
Any info or advise would be awesome!
Thank you in advance!
Wow, that is strange.
Do you have access to one of those wattmeters to see how much current and how much power you're pulling? Have you tried to run the motor with no load, as in taking off the prop?
Also make absolutely certain all your solder connections between the ESC battery connector and all three phases of your brushless motor are solid. If vibration is causing a bad connection to get flaky, that might do it.
Another thought, can you run your receiver on a separate battery pack? If you do so, don't forget to temporarily disconnect the red wire of the ESC servo connector by lifting the plastic locking tab and pulling the red wire out. Be sure to cover that lead with tape while testing.
Do you by chance have access to another ESC?
