Hi,

On quite a few stores, they mention that the warranty will not be valid once the device has been soldered.

Can I check if there's a way to test if an ESC is OK before committing to soldering it?

The flight controller is easy enough to test using USB power and I have tested with without the ESC connected and it's all working OK, but I can't think of a good way to test the ESC.

Thanks

Theoretically, take a motor, solder crocodile clips to the end of the three wires, carefully clip each one to a pad on the esc you want to test and then spin it up in esc-configurator. At least that's how I would do it. Just make sure the clips don't touch each other or end of esc.

So just to clarify something, since most ESC support 3-6S, I would suggest you don't use 6S motors. I would look through your parts box for a motor that uses 3S, then do the above. Power up on the lowest voltage your esc will accept. So most 3S capable esc will probably work on 2S, but maybe it won't output 9V on the BEC, but who cares, because we are spinning up a motor to test an esc, not powering up a DJI/WS/HDZ unit. So plug in the smallest cell count Lipo you have (within reason), then test to see it spins. Most 3S motors will run 2S.

Thanks Pathfinder, that's a great idea with the croc clips, I should have some pretty small insulated ones that will work for this.

I have the Vifly shortsaver and will also use a bench PSU to be extra safe, and also have some 4S (2400kv) motors that I can use also so will be able to use a lower voltage for testing.

I checked the specs for my flight stack (SpeedyBee F7 V3 BL32) and it does say 3-6S LiPo, so will go for 11V on the PSU.

I'll test 1 motor channel at a time, and one I know they are all good I can break out the soldering iron.
