hmm i've heard that the cc10 does not like the outrunner motors. It might not be a noise issue it may be the feedback from teh motor to esc.

Keith, which ESC are you running by the way?

i've run the schulze 11.20 and am saving it for a later project. I currently run the hacker master 08-3p. Both work great in governor mode.

Ah ha! That explains the differing results we are having.
It seems like the CCP10 is doomed not to be used in the Hornet!
Myself, Blade X and Tele are all running CCP10 and even with the ground and aluminum foil on our rx's still get the random cutoffs.

yeah that is the problem probably. I did get cutouts with my escs before i grounded them though. So even after changing escs you'll want to ground them still.

I have tried this thicker wire and so far so good, 5 batts and no cutouts.

that this dosnt work then I will look at making a small farradays cage for the motor.

then it that doesnt work, possibly a filter from the motor ....will need to look in to that ....

so possible causes...

RX interfearence...but the servos dont glich??? ( discounted for now)
servo wire..possible
motor feedback....yet to test
motor can noise...yet to test

please feel free in debunking any of my sugestions I am open to ideas and sugestions from learned and experienced friends....lets solve this problem and free the axi users of the world ...ok maybe not so dramatic

Cheers doug

you shouldn't need that thick. I'm just using a piece of servo wire that i saved when i shortened my servo lead.

Should the thicker wire be soldered directly to the board or does soldering to the exisiting wire suffice?

again, you dont' need that thick of a wire. a spare servo lead is more than enough. very little current runs through the wire...much less than the servo uses during operation.

You don't need to solder it directly to the board. you can just solder it to the negative wire.

SIGH.....
Just tried the thicker servo wire trick and still the cut outs are there..
worst part is I crashed... but not due to cut outs but pilot error
Looked away for a moment and looked again to find the heli inverted!
Was in normal mode and had to hit hold... broke the boom again

Fit,
I just looked back to your picture. From what I see, am i correct in that you have your esc underslung and to the rear, inline/below the gyro?

cyclic, thats the receiver. In the latest flight, I added aluminum foil to the rx as and added protection. My esc is mounted as far forward as possible on an extension right at the front. It just clears the front of the canopy.

So I have my esc as far away from the motor, my rx as far away from both the motor and esc as I can get, rx wrapped in foil and motor grounded to the esc and still the P10 and AXI cut outs.

I've given up on trying to troubleshoot the P10 AXI combo, from what I've read the ms116 escs apparently don't have this problem. So does the Jeti and TMM's too. So I have more or less decided to go for the MS116 esc and be done with all this trouble of trying to trouble shoot it.... and not to mention the cost of crashes due to the cutouts which add up to the cost of a new esc. Just need to save up for it.

Fit,
Probably an all round good move. There is only so much you can try and so much time you can spend trying.

If I'd spent as much time flying the H2 as building, modifying and generally nursing it, it I'd be in the top flight ... or so I'd like to think.

From nose to tail I have messed around with this bird, just see my gallery!

I bought the kit in August - still yet to get the skids up and away, hopefully this weekend though.

I spoke to some one at CC about cutouts some time ago. I was told that what I'm experiencing might be the BEC chip turning off and switching to a secondary backup chip when over heated. I just learned to live with it since it only happens rarely. The momentary drops in headspeed last only a split second and is barely noticed with my autorotation hub. I also don't get the glitch twice in one flight. Those of you with CC10 are you experiencing the same thing or is it more severe?

(CC10, Himax 4100, FMA rx, Hitec servos, TP1320)

scratch building is not just for planks

FIT,

Sorry about your crash but we've already established that it was the cc10 that's probably the problem not thicker grouding wire. The grounding wire isn't running a lot of current so it doesnt' need to be that thick. The esc doesn't need to be that far from the motor...mine is only 30mm away from my axi. It should also not be that close to the receiver. Since you have the cc10 it doesn't matter how close it is to the motor. Its probalby a feedback problem from the motor to the esc. A ms116 or hacker master 08-3p

the hacker 08-3p(Jeti) is fine. I've been using it with no cut outs after grounding it. others have had no problems after grouding either.

mmm thats not good to hear fit that the sugestion dosent work. so fary mine has been ok but I have only done 5 batts..have yet to take it out for a full park test.
if yf22k is right and its a feedback problem from the motor is there any way that we can filter it out, using ferrite rings or things of that nature>

I can get 3 small ferrite rings and get about 3-4 turnes throught the rings ..what do people thing would this work?

Hmm i dont' know of any ways to fix the problem with cc10/axi or twister. I stopped using it back when i had my himax because it would glitch sometimes and I couldn't use the governor mode, which works well on the hacker and schulze esc's and from what i've heard the ms116 as well
