Castle 50 Edge lite and FM9
« on: July 28, 2024, 12:44:11 PM »
I am not sure what I did but I noticed I am not getting the cut off (sag) in RPM a lap before the end of the flight.

Is that setting the FM9 or the Castle ESC?

I looked at the basic program for the Castle and it did not jump out at me. I think my timer is set for % of power so not sure if it is a option with that setting???

It is the FM-9.  1 second -0- throttle at end of the flight time followed by 5 seconds full throttle then cutoff.  I think it is built in and not a setting anywhere.

Thanks Ken,
Maybe I am just not hearing it. My wife thinks I do need hearing aids.  :)

It is hard to hear especially if you're in a manuver. Doesn't bother me because I fly the pattern every time so I know it won't leave me hanging. If you're just going to do random stuff, maybe have a stop watch with you?

Found this on Ebay.  Cheap countdown timer that resets automatically.  One button to push when you start the timer.  Can't miss your wrist beeping!
Strap is another cheap IWatch strap that I screwed to the timer.

Paul,
Playing around with a Phoenix Edge and FM-9 tonight without a prop on it sounds like the faster the motor is turning, the more pronounced the RPM drop is 5 seconds before the end of flight.  For example when I run at 9800 rpm, I can hear it when flying alone.  If there are people flying gas nearby, no chance.  I think that at 10000 rpm, the difference would be enough to be easily detected.  Set your timer to 1:00 and see what you can learn next time you are out.
