I built an X6 quad with LED4Power’s new spacer:

Thanks for all the parts Led4power. Everything arrived in good order. At first, I wasn’t completely onboard with lighted tailcaps, but they are pretty cool. They might even help me if the power goes out. One build done and more to go. Waiting on some parts.

Is the LD-B4HV going to back in stock soon? Or do you have something else planned? Also, I’m highly anticipating the release of the Subzero.
If I have something selected as being in my wishlist, will I automatically get an email once it is back in stock?

Thanks for any help.

 I don't plan to stock LD-B4HV anymore. I'm not sure about automatic mail sending, so it's better to check site and and this thread occasionally.

Any news on the CULPM1.TG yet?
I really want some of that boost hx Smile

Any suggestions on what to use for a thermal path with an LD-A4 and a S2+ host?

Reading through the thread again I realized I ordered a 12A LD-A4 with the intention or using it for a triple, misunderstanding the use of a MOSFET on this style of driver and don’t have anything to use as a heatsink. It’ll be going in a kiriba-ru triple copper pill, would some of those silicon thermal cubes suffice?

DarkShot, this aluminum spacer is probably meant for such duties. You could also craft it from copper if able, or something similar. The dimensions can be easily figured out, height is the only measurement which can leave a bit of doubt but this is easily solved making the part a tiny bit taller so you can sand down reduce it if needed later.

Cheers, the issue at hand is those thermal kits are out of stock, and if they were in stock they still wouldn’t work, as I’ll need a single hole for the triple pill I intend on using. If I had some machining tools at my availability this’d be done in short order but I don’t unfortunately.

Thanks for the suggestion though!

Due to larger number of orders and some other projects that I must finish, those stuff is unfortunately postponed.

Still waiting for the FET switches and den 30A drivers :).

My order arrived yesterday! Had everything arrive extremely well packaged, and everything went together almost without a hitch!

Unfortunately it looks like the RGB LEDs don’t like heat or I otherwise ham handed something, ‘cause one of them the red channel no longer works and I managed to kill another one. This was 100% my fault, it arrived perfectly functioning. Time to source some new RGB LEDs!

Additionally, where could I add a bleed resistor to an LD-x4 that I didn’t select as an option to use an illuminated tail cap?

LD-x4 doesn't use resistor for bleeder but small jfet transistor 2SK3796 (you will see 3-pin empty space for it on driver - if you ordered one without bleeder option), parasitic current consumption during driver ON time is significantly lower compared to resistor (1mA vs 6-20mA).

But adding ~300Ohm resistor  between driver spring pad and gnd ring would work too.

When they become ready, you'll see them in store.
