Lost RPM during flight

[frenchusa]

I have Goblin 700, ikon set with governor, Castle 160. During flight, I lose rpm for a short amount of time.

I attached scene shoot of the log file!!

What could be be issues?

It is a bit of a job to see things when you do a screen shot with every thing on it...it is better to load the file....But looking at your voltage you have a min of 33.4v at one point which might have tripped your low voltage shut down...

Its always easier to load the file so we can view and control it in our own software, but Im not noticing anything remotely close to trouble levels other than the low voltage.

The default "auto" lipo value will set for 3.2V per cell and you hit 2.7V according to your logs minimum value, so that was likely the cause of your momentary shutdown.

Lower the voltage cutoff value, or better yet set it to some custom and ridiculous low value that the pack will never get down to and disable it altogether, just as long as you are timing your flights properly and not draining the batts too low. Just be aware that setting it to anything other than the "auto lipo 3.2V" also disables the cell count when you power up.

While you are at it, make sure the current cutoff is set to "insensitive" so it doesnt do the same thing to you every time you get close to the ESC rated current limits for a brief second.

The less things that the ESC tries to babysit for you the better and the less likely you are to have shut downs for silly reasons like this. I myself have both current and voltage limiting completely disabled and have never had a single shutdown issue ever in many years of using Caslte products, but once again Im keeping tabs on how long I fly and making sure my setup is ideal and not stressing the ESC.

Any improper setup or over stress of the ESCs rated values will eventually result in an over temp situation and eventual thermal shut down, so that is my one and only automatic monitor function. Castles shut down at 100C/212F, and you aren't even close, so your ESC is not being stressed at all.

Your motor power out averages look pretty good at 75% average with 90% max which tells us you are geared OK for your current setup, head speed and flying style, so you will be fine turning off the current and voltage limiting IMO.

Thanks guys, let me check those setting
