I have got this working nicely, both pass through and telemetry. However I am getting a odd limit in RPM. It like I only have 10% throttle. I’m not sure if its a Arducopter setup issue or a BLHeli issue. I am using the same multistar 51A as in the demo.
At full throttle I should be at 8000 rpm or so not 500. It is not throttling up enough to take off. Have tried Dshot150 and PWM both with the same results.
