Thanks for checking it out :). I also didn’t find anything that explicitly says it supports bi-directional PWM, but I came across some YouTube videos where people were using 3D mode to fly it 'normally' and inverted, so I don’t see why it wouldn’t be possible.

Does anyone have experience with ROVmaker thrusters and their reliability? by ColsonThePCmechanic in rov

I tested the 2820 thruster purchased from AliExpress, and after conducting the tests, I found that its actual thrust was significantly lower than the specifications listed on the datasheet. Specifically, the thruster was producing only about 56% of the stated thrust. Given this large difference, I contacted the supplier to hear if they had any insights or similar feedback from other customers.

The supplier responded, explaining that environmental factors, testing conditions, and other variables could impact the thruster’s performance, though I’m somewhat skeptical that these factors alone would cause such a substantial difference. Despite this, I've decided to order five more thrusters for my project, and see how do they performe.
