433MHz lost model tracker


Over a year ago a friend lost a Easyglider with a HD camera on board. We spent a week searching about a square Km of grass and scrub but didn't find it. We also flew many patterns and recorded well over 20 gigs of HD video, finding a few interesting things but no plane. Then a few months later an FPV plane went missing at a much worse location with almost no chance of getting it back; all scrub, forrest and steep hills.

We'd talked about lost model trackers for some months before loosing a plane so this was the push needed to do somethig about it. I designed a 433MHz beacon transmitter and receiver specifically for lost RC model tracking.

So far it's worked well in testing and maybe due to Murphys Law we haven't missplaced another model. I did leave a model in the top of a large tree overnight a short while back, but knew where it was. It was a good tracker test as it started transmitting as expected and I could receive the signal from home, almost 2Km away.

Since then I've supplied a few of these. I have just recently been testing a yagi directional antenna that packs up to a small size and weight for easy storage and shipping. All lots of fun.

Do you ship to Canada? Or are there other places closer to me where I can get some of these? Can one just use the transmitter and listen to the beeping as a way to find a lost model without purchasing the receiver?
Cheers
