DIY Lost Model Alarm for RC Plane

My Champ with bush tires
Earlier this summer, I bought and quickly lost a Hobbyzone Champ ultra-micro RC plane. I needed a Lost Model Alarm. Correction: I need to make my own LMA!

On my maiden flight, wind blew the light, 1.5-ounce plane away and I lost sight of it over the trees.

I'm not the only one. Many other Champs, and maybe other ultra light UM (ultra micro) planes, like those from Parkzone, have been lost by newbie pilots. (Some neighbors found mine, thankfully).

Dorkbot PDX Circuit Boards Delivered

The printed circuit boards I recently ordered through DorkbotPDX arrived!  My very first professionally fabricated boards!

To my eye, they look great. Nicely plated pads, solid dark purple solder mask, nicely done thin traces, and the silk screen looks really good, especially considering how small I made it.
