    APD controllers?

    Everything was going great and it was happily putting out 33kW, until it didn't. Whatever feature that is supposed to prevent over-current didn't apparently. I'm not sure how much value is left, but I'm happy to let it go to someone that can use it.

    APD controllers?

    MGM-Compro display

    Like new condition, with bezel. 5V power supply. Used briefly for a development project, works as advertised for the HBC280120-3EI with "RxD / TxD (RS 232 TTL) galvanicaly isolated". $550 new, I'd take $250 OBO.

    Self-launching sailplane conversion

    The electronic braking provides about 15lbs of force measured tangent to the rotor, I'm hoping this will be sufficient to prevent windmilling but I don't know until I do some flight testing. I have a mirror in the cockpit to verify the prop is vertical, I hope I can rotate the motor slowly...

    Self-launching sailplane conversion

    I though an update might be of interest. I've made the first taxi test recently, and all is well so far. I'm hoping for first flight next week, depending on how the ground testing moves along. I'd be grateful for any input from the members here, as I've yet to have my design vetted in-person...

    kWeld - "Next level" DIY battery spot welder

    I've been having fun welding bits of metal together with my new Kweld but it's not beeping at me as described in the manual. Is this something I can fix? Thanks!
