Copy that. Thanks again.
Good day @zhangsir
Can you post a screenshot of your heli setup?
Just wanted to compare my setup with yours.
I also used a Kakute F7 Mini but cant make the motor spin even if the heli is ARMED. I am thinking that I have the wrong setup. I connected my Servo 1 to M1; Servo 2 to M2; Servo 3 to M3; Tail Motor to M4; and Motor to M5.
The servos and tail motor work but the main motor does not.
Hoping for a response.
Thank you.
Hi, did you figure that out? Iām trying to do something similar.
Hi, I also wonder your motor and servo configuration because Iām stuck as well on this part.
Hello,
I believe this message was sent to me in error. Although I did play around with Ardupilot I never got it. Please double check the addressee you intend to send it to. Best of luck.
It seems to be an old post, but still interesting from the point of view of customizing k110s for Ardupilot traditional heli instead of k120 and for a 1s battery instead of 2s.
I think it is doable without replacing the k110s ESC and brushless main motor. I am not sure what is the output voltage of ESC being fed to the stock FC board, but whatever it is, connecting it to a mini boost converter to step-up to 5V for powering a F4V3S flight controller and other boards such as AC900 Mini S-FHSS receiver (which will work with the XK Tx), a micro brushed ESC for tail motor and a GPS. In this way, we donāt need additional BEC and the stock ESC will cut the power once 1s battery voltage drops to minimum.
I think the biggest advantage of k110s is the 1s battery and it is still very popular and durable with most of the parts available. The k120 is phasing out and I am not able to find much for it.
Did you calculated the extra weight of all additional modules against the available thrust of the k110s?
I estimated an additional 20g weight compared to the stock k110s which weighs 62g. The weight breakdown is like thisā¦
F4V3S PLUS FC [8g]
AC900 Mini S-FHSS Rx [1g]
1A Micro Brushed ESC [2g]
SlimLynx PNVT003A0X3-SRZ [2g]
Matek M10Q-5883 [8g]
VL53L1X [2g]
GL9306 [2g]
which counts to 25g including thin enameled wiring less 5g stock FC board. I donāt know what is the available thrust for stock k110s but it seems will work with 82g.

Did you try to do such or it is just a hypothesis?
Work in progressā¦ the boards have arrived.
Also found an alternate for PNVT003A0X3-SRZ, waiting for it to be delivered!
