Here's a quick video from the airshow we saw last night
(after a successful search and rescue flight)
night airshow (1 min 26 sec)

It was cool seeing an aircraft with fireworks on it.
(I have my pyrotechnics license and am actually shooting 2 shows next week in Utah).

To continue the theme from above.
I am currently prototyping a bunch of different circuit boards for FPV use that I hope to make available in the next few months.
I might be letting the cat out of the bag, but one of them is an RF beacon board.

Description: rf beacon
The one on the left is my prototype and the one on the right I just got back from the board shop a few days ago and I hope it's the final one.

The beacon is customizable through a serial port connection. From there you can select a large range of frequencies. The RF output section is optimized for 433 MHz, but it can also set to transmit on the FRS frequencies (so you can use a $5 hand held to find your plane).
The board will ship with a 1S lipo for backup power and it will also use power from a servo connection. It can be configured to monitor a servo channel and use that to determine when to activate. It can activate on a failsafe high or low setting, servo inactive for a period of time (like watching the elevator servo) or loss of servo signal (crash and main battery disconnected). You can set the number of minutes to delay after a servo trigger and you can set a delay time when no servo input is ever detected (like a kitchen timer).

If you hook it up to a GPS (and you can tap into your OSD's GPS signal) it will constantly update the last GPS position. When the beacon activates, it will transmit the current or last known good GPS position in the RF stream. You will need an decoder circuit to capture and decode the signal to retrieve the GPS coordinates. (I haven't started working on the decoder circuit yet, but hope to start when I finish my other projects).
The beacon will still work fine without the GPS, you will just have to find your plane like an RF fox hunt.

I thoroughly test my boards in my planes before considering selling them (my plane has several of my boards in it right now).
This one could be fun to test because a real world test means crashing my plane out of sight and finding it (and I would need to do this several times).

This is just one of 7 or 8 other boards I have been working on the I hope to make available real soon.

Success!!! It was right where we spotted it!






Ended up here in a crack in the rocks:


It must have went in fast, I think inverted too:









My Vtx and antenna look to be completely unscathed though!



Salvageable parts:
-Servos, at least 3
-Reciever
-Vtx and antenna
-ESC (maybe)
-Collet prop adapter

The tail boom and stabilizers are also in great shape and the wings aren't too bad either, just a little scuffed up. Spares for my EZ*!


Thanks again Damon and Jeff! Couldn't have done it without you guys!

Hard to believe the battery didn't catch fire.

Congrats on finding it.

Thanks guys. Here's a vid of me climbing down to the crevice. I had to go up on the right of the boulder, up along the top, and then down to the hole.

Also saw a baby rattlesnake up there!

GREAT SUCCESS!!!

LOL that's within 50 yards of where I was going to look.

To bad you weren't also recording on-board. Would've been cool to see the impact.

I'm sure that LiPo has seen better days. Make sure you dispose of it correctly.

Even with all the damage, it has to feel good to be able to get her back.

Cheers

Saaaweet,
Glad you recovered it, too bad it's a little banged up, but at least you got the electronics back.

I wanted to wait until the plane was recovered before posting these.

This is it's final resting place in google earth.

These are the full rez pictures from the rescue flight (it might be hard to spot at first, but once you spot it, you will see it in all the pictures.
(I have a few other pictures with the plane in it, but it's even harder to spot)

There IS an old dirt (but flat) runway going parallel to the main road on the North side there....

Awesome work all!

These are the types of events where the FPVing community is brought together and reminds us all that someone is out there willing to help out. It really brings us all together. Nice job, most extensive recovery I've seen all put together by people on a simple online forum.

Nice,
Ugrd

Simply amazing! Congrats on the recovery! And how cool that you got to meet up and "work" with other, local FPV'ers in a real plane! AND see a cool, night airshow! WOW!

Excellent story with a happy ending. What a great community on RCGroups to go to so much effort to help. Makes you feel all warm and fuzzy.

Nice work guys! You should be proud of yourselves.
