e-Century Hummingbird - Swift > Century 85/110 esc cutting out midflight.

Have a century 85/110 hv esc has about 10 flights on it and has cut out 5 times midflight for no apperent reason.Just shuts completley down for a second or so and then bang it's back to full power as fast as it shut off.the temp on the esc after flights is 75 to 80 degrees.every time i have maintained radio control so it's not the bec or a bad connection. I had it in my 620 first and it did it in that heli twice and now today 3 times in my swift 16.usauly only a minute or 2 into the flight and usauly under light load when it happens.the last time was in the middle of a flip and it saemed to take longer to come back.my last century esc did the same thing and i never did figure that one out i just upgraded to a castle and never looked back.after oldfart reassured me that the new century esc'c were better i decided to give theme another chance, besides at the price of the 620 combo it was like getting it for free but now that it's endangering my heli it's a different story.Especaily with a nondriven tail heli.I took it out of the 620 so as not to endanger it( being alot nicer heli)I have several flights on it now since putting in the castle hv 85 and no cutting out anymore.So if anybody has any idea's I'd like to hear them other wise I'll replace it with a castle and NEVER!!!!!! buy another century esc again!!I also noticed that i lost 150 headspeed with the century esc and the motor is running very hot with century esc.I had a cc hv85 in this heli and i put it in the 620.with the castle esc i had more headspeed and the motor ran cool 75 to 95 *maybye century esc's don't like neu motors.although in the 620 i ran a 650a century motor with the century esc and same problem with the cutting out.But the century motor did run cool.

I think more info would help.

What batteries and their configration?

What pitch range?

What throttle settings?

Are you in gov. mode?

What are you using to power your RX?

What KV version of the motor?

What pinion?

Problems like that are sometimes a radio problem. It’s especially a problem with Spektrum receivers and some FM systems. PCM or the new Futaba FASST radios seam to be the best solution.


What radio do you have?

in the 620 i have the futaba fasst 2.4 and inthe swift 16 i have a pcm 72mghtz jr receiver.
I have ferrit rings through out and the receiver and antenna are as far away from the esc as possible.since this problem has followed the esc,I'm thinking it's faulty especially since twice now when spooling up the slow spool up whent crazy and almost caused the heli to crash before it even left the ground.

Are you sure it’s not a static discharge problem – ground the boom to the negative side of the battery.

If you've changed end points, adjusted your transmitter, etc, please reprogram your ESC.

If you need help, please refer to the instructions found here: http://www.centuryheli.com/support/...electron_85.pdf

well i tryed the static idea by spraying the belt with silicone spray.and i also talked to heliworld today and they mentioned the motor wires can't be close to any other electronics and mine are not.they also said to run non govenor mode and a flat 100 throttle curve.so i did all those things ,sprayed the belt,rste esc to non govener, and flat 100 throttle curve.I only flew it for 3 minutes besause of the motor heating issue.but so far no power cuts.however with the 100% flat throttle curve in non govener mode the power definatley was off.witch is what i've found to be true before with my castle esc's.I was told with them that you shouldn't run much past 85% in govener because there's nothing left to acceleerate for pitch changes .and sure enough tonight i could definatley hear it bog with the 100% setting.Century seemed very interseted in the heat issue with the neu motor and the century esc. it seams they've had simular problems and they ,like myself think the esc doesn't like neu motor's,they asked me to switch it back to the castle hv 85 and see if the heat issue goes away again.But it's a pain to unsolder everything and rewire every thing in 2 helis twice to try it and besides i already ordered onother cc hv 85 this morning for it.With the century motor and cntury esc the motor ran cool.so i think it's a timeing thing and the century esc isn't programmable for timeing like the castle is.I've been told by a neu rep that there motors like low timeing.so maybye thats the difference.for now i think i will wait for the new castle esc to get hear so as not wreck my motor and then just keep that century esc paired with one of my650a motors.Unfortanatley the century esc will only run 10s and i'm currently runnig 12s on both my 650 motors.

Sorry about the paragraghs. I didn't get good grades in english in high school and only went to technical college for 2 years.
But i will try to do better.
And yes i have been know to talk to much when discussing subjects that i find interesting.
And i find heli's very interesting

Like I said in a previous post. Try grounding the boom and frame to the negative side of the battery.

i've been told that spraying the belt with silicone stops static also.
So the other night thats what i did.So far it's working.
But I'm haveing a second problem with the motor overheating with the century esc.So i've only been flying half the battery at a time.
Like i said a couple posts back,after talking to century it appears that the century esc and the neu motor do not pair well.
So i have a castle on the way for it.
But if it makes you feel better The next victim that gets this esc will get it's boom grounded.
