Was doing some work bench cleaning and found two HobbyWing just stock , a speed passion GT 2.1 and a practicly new Novak. All are non working and was wondering if anyone here ever sucsefully tried to repair or knows anyone that can. Thanks

It wouldn't be worth the cost to try to repair the HW Justocks, Novak's gone altogether and as far as I know, Speed Passion doesn't have a US service center, just replacement of like for like on warranty claims. There is no credible third-party ESC repair that I am aware of.

That's a shame. These are just paperweights I suppose

Hard to diagnose since everything is surface mount on the PCB's. You can open you hobbywings and try swapping cards if there is two cards. that's about it.

Ok good to know thanks
