Could someone help me with these old-gen v3.1 Plushes ?
They sould be ATMega ones by the date I bought them (mid-2011), they've got pads in a row on the upper PCB, there seems to be 3x4 4166 NFETs, but I can't find any pictures or information on the web to confirm all of that.

So if I'm right, I've got 2 questions :
- which SimonK firmware should I use ? TGY ?
- could someone give me a hint of the mosi/miso/.... sequence ?

Thank you !!

New Model of HK-40A ESC?


Hi,

I recently got four HK-40A ESC for my first quad. After reading some about flashing ESCs for multirotors I decided to do so and looked up my ESCs in "The List". There I found the rct50a.hex for my ESCs. But after flashing all motors only stuttered, even after changing the wires. So I removed the heatshrink completely an realised, that my ESCs look different from the picture (see my picture). After checking all the other images in "The List", I came to the conclusion, that my ESCs look more like the Robby Roxxy BL-Control 730 and I have to use the rb50a.hex. That flashed, the ESCs work perfect!

So, to make an long story short: If you have the HK-40A remove the heatshrink an check how they look. If they look like mine use the rb50a.hex.

Hope this helps someone.
Sorry if this has allready been posted, but my quick search revealed nothing...

Have fun!

GO to the google doc with all the compatible ESC https://docs.google.com/spreadsheet/...BQkZZRlE#gid=0
And search for your ESC, there is on column with the firmware type to use. It is TGY for your ESC.
To make it easier you can use my tool from kkflashtool.de to upload the right firmware. You don't have to download anything more. The tool downloads the firmware for you. Just select Programmer, ATmega8 based ESC and the tgy.hex from the dedicated dropdown boxes.

ESC starts spinning at full throttle


Hi Guys,

I have a question. I have a flashed my ESCs on my octocopter. Today I went flying for the 10th time with this system. Somewhere during flight one of the motors went spinning at full throttle. The octocopter started to compensate, resulting in all motors spinning at extreme speeds. This resulted in a extremely fast climb and finally in a crash.

Any ideas how this is possible?

Thanks!!

I doubt it is my DJI FC. I never had any problems with that. Any other suggestions? Interference? Calibration?

Anything.
Bad connectors. Bad hardware. Shortened wires....
n+k causes, and you didn't even wrote which ESC's and which FW are using...

Sounds like it was on the way to homeland.
I can assure you it had nothing to do with this firmware though.
Perhaps you want to order some *** ESC to go with your *** controller.

Changes to Hobby King F30-A?


Does anyone know if Hobby King made any changes to their F-30A ESC? I flashed three of them for a Tri and they all flashed fine. When I put a battery on them the magic smoke came out almost immediately.

When I remove the shrink wrap the first component that connects to the red motor wire is fried. Thought it may have been a short the first time, but on the second run it fried a motor as well.

Used the latest software off the site with the kkmultiflashtool.

I have six of these same ESC's running in a hexcopter that I made last year and they work great. Not sure why they keep frying this time.

What firmware did you flash it/them with? That side looks identical but pics of the other side would be useful

Hi, Neal! The capacitors are, in theory, for allowing the code to be more simple in how it deals with noise on the sense inputs. However, it also lags the detected zero-crossing, which makes the motor timing not consistent over the RPM range and in some cases it can make it more difficult to start, since starting has to be very sensitive to anything that looks like crossings as it has no idea what sort of motor is attached.

See the spreadsheet and previous posts on the subject.
