Hello. I’m new with using Ardupilot and MP. I’m currently set up using the Arducopter with the Quad - X configuration. I’m using the Herelink Controller and was curious, do the throttle controls input reflect the what the output is in motors?
The controller has been calibrated in both Herelink and in MP. The sticks are centered when released. I did no custom modification with the Herelink controller, it’s straight out of the box.
During my bench testing, after arming, the motors spin up, but do not change RPM when I throttle up. I do hear a difference in the sound and can see changes in RPM when I pitch and yaw with the sticks.
Am I missing something in the configuration?
No, likely not. A bench test using the controller tells you nothing. If you want to test the motors connect to Mission Planner and use the Motor Test function.

Thank you Dave. I did the motor test in MP, under the Motors options, and they all tested correctly. I wasn’t sure if testing the motors in the flight control modes were possible.
That test doesn’t tell you anything other than the motors turn and in which direction.
Correct, that is why I was wondering if there was another way to test if the trust output RPM was increasing with the inputs from the controller.
Sure, put props on and fly it. Otherwise it’s open loop with no feedback from the sensors so the motors will do random things.
OK, Understood, that answers that question. thank you.
I was curious, did you ever fly it, because I having same problem, but I think my 3s battery isn’t strong enough and or I to much weight for motors and propellers !
Post more details and we can help determine whether the hardware is suitable.
Otherwise, put it in stabilize mode and try to take off. Bench testing RC throttle control is not really a useful exercise.
@Yuri_Rage Hello, i.m almost at my wits end haha, but I’m going to keep on trying to fix it.
My setup:
cube Orange, T-motor MN3508 Kv380, 40a esc, 1045 props, 6400mah 25c battery, frame
Readtosky ZD550
The total weight with battery and camera is 3.6kg
If I use a 6s battery, would it fry up anything, I have the air unit on and esc on this : Acxico 2 pcs Drone Power Distribution Board XT60 3-4S 9-18V 5V 12V Output PDB
I took it outside and try to fly, and seems like the motors are not spinning fast enough to take off, Also how do I get the .bin file to post what it is doing?
Pull the SD card from the Cube Orange, or download it via Mission Planner.
That combination looks unflyable. A very quick and dirty run of eCalc shows it doesn’t even have hover thrust.
I have the same frame and ran 700kV motors and 10-14 inch Master Airscrew props on 4S with an AUW of about 2.5kg. The bigger props were definitely more efficient, but it flew on 10".
I now run 11 inch triblade Master Airscrew props on 6S with 660kV motors, and it’s a beast. I have about a 1kg payload capacity (maybe a little more) over and above the 2.5kg basic weight. This config nets a little less flight time per Ah but is quieter with more payload capacity.
In short, I think you need higher kV motors even for 6S. And if your PDB shows 3-4S input, it won’t handle 6S voltage.
As @Yuri_Rage said that will never get off the ground as configured. At that weight you would need 6S power, ~780kV motors and 11" props. But 3.6kg is probably too much for that frame in any case.
IOW you built a turkey.
I agree with this sentiment. I should’ve been more specific when I mentioned the 1+ kg payload capacity in the present config. I have indeed lifted over 1kg (taking my AUW to about what you desire) and done some basic hover/stability testing, but the duration dropped substantially, and it was really working hard. Useful payload is probably about 500g.

I have joked before about what to do with this frame or one like it loaded down with high vibration. It involved JB Weld and the folding mechanism…
If assembled well (and not worn), the folding arms aren’t so bad. Granted there are far better out there, but I like this frame for the price. Its biggest downfall, IMHO, is the motor mount hardware that makes it extremely easy to create a yaw bias (or end up with one after a mild bump of the mount).

I have flown it on the 450mm frame, but I crashed it and broke the arm, so that is why I went to that other bigger frame. When I flown it, I had 750kv motor with 1045 props with 5000mah25c battery for 10 minutes. But I figured to go lower kv motor, can I get a 6s battery and bigger props to make it fly on new frame?

Im not sure if this is a good log
That log doesn’t show anything. I’m guessing there were no props installed?
