Compatibility of (VOXL ESC FPV 4 in 1 SEC) with T-motor MN2806

[Tamilselvan]

Is there any possibility to use T-Motor MN2806 with VXOL FPV 4 in 1 ESC
if we can use kindly share details how we can integrate

Hi @Tamilselvan,

Yes, our FPV ESC should be a good match for this motor in terms of power, however you will need to perform tuning and testing (non-flying) to prevent de-syncs, as described here:

https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/doc/low_kv_motor_tuning.md

You would first need to follow our standard tuning guide as described here, but first increase timing advance and sense advance to the numbers from the above link, so that you don't have a de-sync during calibration : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/calibration.md

Please note that the FPV ESC only has the total current sensing, so you would want to run the tests with the ESC ID2, which measures the total current, so it will be reported to the python test scripts.

Just for full disclosure, we do not do a lot of testing using low kV motors, but the parameters are there to adjust and test performance. You would need to do sufficient bench testing to convince yourself that the ESC tuning is good and you are ready to test flying. If you need more guidance for testing the ESC performance, I can help you. You should first start with the link I mentioned above and then modify the script to run continuous tests and perhaps detect anomalies. We may extend our test script to support testing like this with automatic error detection in the future.

If you do not have experience with ESC tuning or do not wish to go through this procedure, then our ESC may not be the best choice for this motor.
