I thought I had a thread started but I can't find it.

So I'm looking back through some flight log data while my motor is being repaired. I noticed that the amperage recorded by both my meter and onboard data logger showed that amps dropped when I switched from automatic to fixed endpoints (ESC setting). I think it went from 75 to 70A or something. I don't really understand this.

I know the readings we get are an average current and I'm just trying to make sure I know what I'm doing so I don't lose another motor.

I also would like to hear about prop solutions - I was told some APC glow props will use less current than the e props due to better rigidity and less flexing. Does anyone have some comparisons to post? I'd totally be down with a CF prop or something if I could use the same size and drop some amps.

If your TX full throttle setting has a lower pulse width than the fixed end point on your ESC then you won't get to full throttle. ie, you set your TX to 1.8ms at full throttle and then set your fixed end point in your ESC to 2.0ms, then the ESC will never see a full throttle signal from the RX. Might be your issue, just a suggestion.

What ESC are you using?

I'm using the CC ICE HV 80. To setup the radio with the ESC, I put my endpoints in the middle, then advanced the high endpoint until the ESC recognized full throttle - it gives a beep. Did the same with the low endpoint. So I think it should be seeing full throttle.

Joe, you are probably right.

I was thinking (yeah, I know, dangerous) about your question. When you switched to fixed end points, you may have also shifted the way your TX throttle curve is working with your ESC. That could affect your average amps readings if your throttle curve is now a little lower rpm for the same stick position.

Throttle curves, end points, etc, are kinda tricky with the e setups and a small change can have a noticeable affect on usage, amps, etc.
