Well, it's been a while since I was last working on the brushed ESC and I finally got some more time to get back to it.

Fortunately while I was busy with the other electronics projects (like the BEC/Alarm combo for the DLG's) I happened across some parts that would allow me to make the ESC a lot more compact.

At the time of this blog entry, the PCBs for the ESC are off at the factory being produced and now it's just a matter of waiting for them to arrive. Due to the slightly moderate complexity of the board I can only hope that I've not stuffed up anything (like a via in the wrong place, bridging another (incorrect) track etc).

I did have some images to upload - but RCG seems to be complaining that they're not valid, despite converting them into other formats including JPEG and PNG

Finally decided to take the plunge and equip the store with a stock of JST-XH plugs/leads and sockets so that everyone can have a one-stop place for their lipo balancing leads.

The JST-XH's are fairly popular with most Chinese packs though they're slightly wider than the 2.0mm pitch used by some of the other brands.

I also restocked up on 300mm, 600mm extention leads as well as 300mm long bare-ended servo leads (good for fixing up those servos that had their leads chewed up or eaten through by friction wear).

All these and a lot more at http://pldaniels.com/rcshop (or http://nqrc.com ) - located in Australia

I recently came across a thread in the Discus-launch / hand-launch glider section (where I normally am for the QuickFlick-II 50" DLG) and I saw a thread about the need for a light weight lipo Alarm + BEC combination.

To cut a long story short(er) I've not got a new product line running, the PLD-BAC, BEC-Alarm-Combo.

* Very low weight - 4.6~5.0g
* Very small - 19 x 12.5 x 8.5mm
* 2S lipo input
* 5V output
* Over voltage alarm (Vin > 8.5V)
* Under voltage alarm (Vin < 6.2V)
* Buzzer alarm
* 1A linear BEC for minimum RF interference
* 250mA constant supply, 500mA for 1 minute, 1A for 10 seconds (thermally limited - better cooling gives longer duration)
* Thermal and short circuit protection
* High quality, low power, low (RF) noise micro controller
* Large copper backplane to improve heat-sinking of linear regulator.
* Supplied with 50mm RX lead and 100mm unterminated battery lead
* Covered with heatshrink for protection against accidental shorts and sharps damage.

I'm selling the BAC's right now at;

There are also future plans for a lost-model-alarm and LED-only variant of the BAC to suit the needs of other people.
