In our second round of testing the mini Talon QuadPlane, we replaced the HQ10x5 e-prop with an Aeronaut 10x8 e-prop. I had also installed a new 12v regulator to power my video transmitter. Although the initial testing went well, when switching to CRUISE mode, there was a noticeable pulsing in the forward motor power level. The plane landed fine in QSTABILIZE mode. A quick look at the logs revealed a current oscillation in both CRUISE and FBWA modes.
My initial suspicion is the new 12v regulator powering the video tx. but I will unpower both for the next test and go back to the HQ 10x5 prop for a baseline. It may also be from my CRUISE mode settings below. I will then retest the Aeronaut 10x8 e-prop as well as an APC 10x8 e-prop.
Below you can see the red current oscillations in CRUISE mode. The green is AS sensor and the red is GPS speed.
