I'll release the schematic soon.


I would prefer to have 2 smd leds :) it is just two smd pabs on top and bottom :p

Instead of the two LEDs where should be a integrated 3A brushless ESC (like HK XP-3A with BLHeli, only a few parts ;) ) for brushless micromotors (HK AD-C5, ...). The LEDs should be moved on the outside of the motormount.

oh man, you are making me fight against opening the schematic tool. I'm pretty sure I can pretty easily attach those onto the arms.

I may well end up doing something like that in the future, but I'm hesitant to open the door to ESCs again: http://buildandcrash.blogspot.com/2011/ ... pment.html

Why a new ESC? BLHeli is open Source, Schematic of a 3A-BLHeli-ESC is also available (http://www.olliw.eu/uploads/olliw-xp3a-scheme-01.png). Only place the parts and Flash the HEX ;)

You are using Altium, is it possible to get the Altium project, to play a little bit with the PCB (non-commercial use!)?

You know you are making it quite challenging to focus on work :-p

It's definitely something I'm tempted to do but for now I'll see how this revision works. The brushed ones are still nice for being super light and safe to fly indoors. I'll probably end up doing this though ... dangit

BrushedSparky v0.2 arrived. I'm glad people suggested LEDs on the arms, I like how it looks:



New VTX modules work well and video is nice and crisp. Also the new switching regulator is much more efficient. Current when not running motors is 400mA - was closer to 800mA on previous board (different VTX module too).

I made a cup that goes over motor mount too which I quite like:



It's a nice place to store the spare length of wire to motors and protects the bottoms in crashes.
