    I’m looking for the original email exchange from Yimin at Youkits and will cut and paste the essentials here when I do.

    I did this mod several months ago when I saw Wes's eBay review. It works as he says--in other words, very well. I used a 1/4 watt resistor because it was all I had in my junkbox. A 1/8 watt would fit better.

    Much better, thank you!
    I won't ask about the polarity of the resistor! :)

    I've got the HB1A Mk 2 mini CD that came with the rig with other stuff on if that's any good.

    So now we need a source for the batteries Youkits will not ship to us. It’s a 11.1v 3S battery and I assume LIO and not LIPO as it has no protection circuit but I could be mistaken. I’m trying to source a supplier (In China) but having trouble exactly matching the battery in the HB1B and with the same connector. Ugh. Anyone know a source?

    Wes, I'm confused by your comment so I opened up my hb1b and took this photo. All very standard batteries, connector, and holder. What part of this is causing you pain? Let me know and I'll try to help.

    3C60B061-B5CA-40EE-906A-F3ECFCB78400.jpeg yours are 14500’s. Mine are 18650’s. A bit more umph. I can’t find the 18650 battery back that I bought from Vibroplex when they had the Youkits distibution agreement with Youkits. Maybe it was Tentec. Youkits won’t ship the battery to the USA. I can’t find the holder you have either. Looked on eBay, Amazon, and all the usual places. Maybe I’m not searching correctly. What is your tray called with that type of connector? Either way it looks like this:

    I know we are supposed to sign our posts. I couldn’t open a text line after adding the photo.
