    For just the driver or does that include the LED/s?

    I have 10W on the quad and it works really very well.. I attached copper forged heat sinks and then mounted them in the airflow.. I tested stationary with the props running for 20m and they did not overheat..

    I just got an off the shelf 10w RGB with IR remote, soldered the stuff up, heatsinks and away I went.. took maybe 10 minutes? 13$

    It would take some doing but a nice housing that allowed airflow would be great.. my "ghetto" stuff is not for the masses...

    At night? it is hilarious... from several hundred feet away, it is just a ball of glare looking at you.. terrible for navigation but wonderful for bringing people out of their houses..
    Poke it with a fork.. done...

    Hugo, do you know where I can buy decent, small easy heatsinks for the Cree XM-L leds? I bought three of the LEDs from DigiKey and three lens for them, but I need heatsinks for them. Does the small "star" PCB design I often see (like your avatar) the LED mounted on function as a heatsink? Or is it simply to make mounting the LED easier?

    The "star" PCB is metal and function as a heatsink, but at this size it can't take a lot of heat. The star is meant to be fixed to a heat-sink and transfert the heat from the LED. You can heatsinks at digikey/mouser.

    I saw some heatsinks at Digikey but they looked relatively huge. As in, designed for using the LED as a overhead fixture in a house or commercial installation, not in a small, flying foam model. Lol. I know the larger the heatsink, the more wattage it can dissapate, but I doubt that I need to drive these at a constant 3 amps to get the output I need/want.

    They will first go an a FPV Traxxas Emaxx. Then, if I like them, I'll put them on my FPV Slow Stick. And maybe on a quad (once I build/buy one...)

    Anyway, thanks for your help!

    Hugo, any suggestions on a LED driver that can drive one Cree XM-L at 3A? Or do I need to make my own, using a high power Mosfet?
