Help with Castle ESC lowest governed headspeed
Just wondering what y'all run / have run as your lowest head speed with the Castle governor activated.

I have always ran 1550, 1800, and 2050 for quite some time and lately I had the machine cut out (graph shows power out at zero)and found a motor issue so I replaced the motor but when I test flew it today, the same thing happened. I then borrowed a buddys Castle ESC, programmed it just like mine, and about 3 minutes into the flight, it happened AGAIN!! I then bumped the lowest head speed up to 1800, mid to 1950, and high to 2150 and flew at 2150 for 4.5 minutes and it flew perfect.

Not sure if the governor can't handle the low head speed as it would frequently not hold the head speed after I unloaded the disc and would take a second to get back on track.

Any ideas?

setup as follows:

Trex 700E V2
CC 120 (borrowed a 160)
Stock everything except the new Quantum 4530-500
Gens Ace 5000 mAh 60C pacs
ARBX.... flybarless

Could it be your one way bearing is letting go at the lower head speeds? Problem is not really ESC. Just wondering!

I don't run the new software. I run 3.27. I believe that is the best version they have had no doubt.

I have to agree with Duosport and check your oneway.

If it's the oneway and you are not holding headspeed at lower RPM be careful.

This may be an indication that your oneway may be starting to fail.

I just had a month long one way bearing battle. Bought 2nd ESC after roughly 10 flights rotor head started slowing again. Usually it was several minutes into a flight as you describe. Tried reprogramming ESC. Early on in trouble shooting I suspected OWB and bought a new one but bearing was pressed in backwards rendering it useless. I thought I would of heard bearing squeal or heard motor speed up or something. Nope, rotor just slowed. A search on RR helped find the cause.

I had a one way bearing issue on my last heli and the symptoms were pretty similar but it won't slip at the higher head speed and on my old machine, I could grab the main gear and hold the head and get the bearing to slip. I can't do that now so I wrote off the OWB. I'll do some more testing at the field today and see what I come up with!!Team me

You guys called it and I should have gone with my initial guy feeling!!

It was the one way. It totally slipped on my first flight today and luckily I was able to auto the machine with no issues. I took the one way out and sure enough just like on my other machine, there was NO red loctite on the steel ring that sits in the aluminum hub. I took care of that issue and also tapped 2 screws to additionally secure the ring and then proceeded to beat the ever living snot of the machine for the next 4 flights and she held PERFECT!!
