CC Multirotor 35 Amp ESCs (No BEC)

I have a Wookong X4 quad running 4 of these ESCs with no problem.

I just upgraded my TBS Discovery/Naza V1 to these. Two controllers arm, two do not (red LED on). They do arm when on a regular receiver at low throttle. Swapped the two which arm with the two which don't on the Naza (M1/2 to M3/4 and M3/4 into M1/2). The lack of arming followed the two ESCs which would not arm. So there seems to be a difference in the low end threshold between these ESCs, and not a problem on the Naza channels. I did use the CC software to reset defaults on all 4 controllers, but that did not fix the problem.

What can I do to correct? Castle tech support did not have any recommendation. They just said the PWM was not low enough to arm. Should I remove fixed endpoint from the ESC setup and calibrate manually using a transmitter and a regular receiver to the highest low point possible? Or upgrade to the latest (beta - not really appealing) firmware? I have not updated the Naza to the latest firmware yet, not sure if they changed the PWM numbers since I last updated it which was about a year ago (was running DJI ESCs). Naza version I am running does not allow me to change the endpoints output.

I hate to send these two back to CC if there is a fix I can do myself.

They have stated they tested on the most popular MR platforms, I'd think DJI Naza should be pretty standard.

Thanks in advance.

it looks like you answered your own question with option 1. Having only setup a V1 Naza for a coworker my experience is limited. I did have unresolved issues with latest fw that was more to do with unfamiliarity on my part than the Naza. firmware is last resort if you have a tuned mr setup imo.

I've verified the Naza is running the latest firmware 4.02. Unless CC tech support has some fix for me to implement, these two controllers are going back.

You have to calibrate the throttle on all ESCs. Especially when using on multirotors. Connect each ESC to the throttle channel of your receiver and calibrate them one at a time. then connect them back up to the Naza.

I thought about that. When I spoke to Castle they said I'd have to go to full throttle to initialize when running (not sure if that is true). Since they are supposed to run on a "fixed endpoints" on multirotors, they are getting 4 units back. Two that initialize and two that do not. I will report back here as to what they determine. Also FYI, I have four of these units running on a Wookong with no issues.

You likely don't need to send them back. Connect each of them one by one to the throttle channel of your receiver hooked to ANY motor with NO PROPELLER. Power the radio on, push the throttle stick to the top, power the ESC and wait for the throttle calibration tone, then push the throttle stick to the bottom and wait for the acknowledge tones. Do the same with each ESC. Then connect to the Naza and it will work.

I already sent them back, but if I have the issue again I will do as you recommended. Question, if I do this, the ESCs will have to be in other than fixed end points mode. Do I leave them in that mode or switch them back to fixed endpoints before using them? Thanks Hans.

I have a procedure detailed for this on the "Multi-purpose Hexa Recipe (Incl. Parts/FPV/Etc)" thread that I created. That thread has also been updated with more info and hardware choice revisions. Give it a read if you get time, but here is just the section you are looking for.

======================================
ESC SETTINGS AND THROTTLE CALIBRATION:
======================================

ESC SETTINGS
------------
Brake = OFF
Battery Type = Nimh/NIcad
Cut off = Soft
Cut Off Voltage = Low
Start Mode = Normal
Timing = Middle/Medium
Governor = OFF

- If you are using SimonK firmware, you will only need to set your throttle range. Al of the above settings are already set/unmodifiable.
- Battery type is set to "Nimh/NIcad" in order to disable the voltage cutoff. It's better to ruin a LiPo than to crash your multirotor because the battery hit Low Voltage cutoff.
- Timing can be set to whatever works best for you. I suggest starting at Medium first though as a base/starting point.
- IMPORTANT!!! When setting up your ESCs, you must set the throttle travel on each ESC. You can accomplish this in several ways. The easiest is to connect each ESC, one at a time to the throttle channel on your receiver only. Another way is to make or buy an adapter that allows you to connect the signal/power wire from all 3,4,6,8 of your ESCs to the throttle channel of you receiver.

Throttle Calibration Procedure:
-------------------------------
- Make sure your Receiver is Bound/Paired to your transmitter.
- Make sure you have a motor plugged into each ESC and NO PROPELLERS mounted.
- Turn all electronics off.
- Plug the signal/power wire of your ESC/ESCs into the THROTTLE channel of your RECEIVER ONLY! (Not your flight controller).
- Turn on your Transmitter and move the THROTTLE stick to the top.
- Using the manual for your particular ESC, find out the throttle calibration procedure. It usually is similar to the following.
- Power your ESC/ESCs on.
- You will hear an initial power tone (and possibly a cell count) then another tone. This is the throttle tone.
- When you hear the throttle set tone, move the throttle stick of your transmitter to the lowest point.
- The ESC will do a beep code and then arm the motors. Your throttle calibration should be complete.

Castle said they check out 100% to their specs. They also said I should do a manual throttle calibration. I bought the multi calibrator board and will set them all at standard JR 100/100 endpoints and hopefully that works and I do not have to set them at some other endpoint.

I would still do the manual throttle calibration. Each radio can be a little different with endpoints slightly varying between two radios set with the same ATVs. The calibration is easy and nothing to lose.

The thing about the manual calibration is that the signal from the radio is re-processed by the Naza to its own endpoints. Since I don't have a scope, I do not know what endpoints the Naza is putting out (to match them to an ATV setting in the radio). So it will be hit or miss as to whether the endpoints I put into the controllers (via the RX) will match up good with the endpoint range of the Naza. But as long as they are all calibrated the same, I figure it should be fine even if the Naza's range is say wider than the ESC's range since the ESC rarely operates at 100% throttle.

And yes, I plan to do the manual calibration as the "fixed endpoints" setup which was the expected use by CC does not work in the case of this particular controller. It does work fine on my Wookong.
