Hi Ripmax,

That's one of the best points about micro FPV. I have to be much more aware never to fly over or near anyone with my normal sized quadcopter. With the Hubsan no one even notices it's there when I fly by.

Unfortunately when it goes down it's a royal pain to locate, even with recorded video to review. I painted the bottom bright orange and that helped a good deal so probably gonna paint the whole thing orange.

There's got to be a way to wire a small piezo speaker the quad and have it beepor shriek when needed. There's also got to be a way to be able to do some sort of directional indicator, sort of like an RF compass that shows the direction your quad is facing.

Is that Sunhans wifi booster that you put under X4 TX?

@ Patrick,
Nice work and write up as always

Hi MO and Gents,
Yep. A light-weight beeper locator would be a nice add-on to prevent micro multicopter losses. Here are some considerations:

From the Locator devices section in the Quadrocopter and Tricopter Info Mega Link Index
--Beacon which uses an inexpensive FRS/GMRS UHF transceiver by FMKit: http://www.fmtv.us/rf_beacon.html and http://fpv-community.com/forum/showthread.php?tid=81 and http://www.rcgroups.com/forums/showthread.php?t=1274173
These are great and only 2g and about $50. However they are best for narrowing down location of the lost model from miles to 10-100 feet due to the signal saturation when you get that close, so probably not the best overall for micros. The FMKit FRS beacon works well and has saved several of my larger multicopters that fly longer distances away. It is a must have item for the larger more visible multicopters.

and

--Loc8tor: store: http://www.loc8tor.com/ , RCG forum: http://www.rcgroups.com/forums/showt...9#post10751721
The Loc8ator beacons weigh about 2g stripped and will locate within inches. It has a short 200M range so it is ideal for the micros. At about $60-$150 depending on the version, it might be too pricey for most micro's, but a good idea for the expensive multicopters...

and

--Some remote key finders can be candidates for locating micro multicopters if the plastic is removed and maybe a smaller button battery too if necessary.
http://www.ebay.com/sch/i.html?_odkw...at=0&_from=R40
I got this one recently and like it because the range sensitivity can be adjusted on the hand held receiver. The transmitter is only 2g when stripped. http://www.ebay.com/itm/Keychain-Ant...item3f1abd8955

--Always put a note with your phone number and a reward offer should be on the multicopters you would like returned if found.

It is best to be redundant with locators if possible, i.e., note + location beeper or transmitter. The model often loses power in a crash, so a separately powered or an additional locator will have the best recovery reliability.
Cheers,
Jim

I have the traxxas QR-1 I painted white first then coated it with day glow green and it POPS so i bet you coat the quad in white and then use a dayglow orange and you will never lose it as it will glow like a street cone!

I considered a beeper for my Hubsan but 2 grams becomes noticeable after adding FPV components. If you have a VTx transmitting video then it's easy enough to locate a downed micro quad with-in about 20 feet with the VRx antenna off. Of course always record video to review as well.

My VTx, antenna, cam, video lipo, wires & connectors come up to 9.7 grams. Even at under 10 grams I have to use 70% throttle on my Hubsan to maintain hover on a fresh lipo. 5 minutes later I'm at 80% throttle and it's time to land.

Building on MO's post...I wonder if it's possible to put a very small piezo speaker that will sound when the eyes begin to flash...basically feeding off the low battery indicator signal. That way you just have to wait until the battery gets low and then you can hear it scream for mama.

Adding LEDs would help too.

If someone doesn't want paint on their motors just use some broken motors as placeholders. Then swap them out for good ones when the paint dries.

I really like your paint job! I may have to try something...got a friend at an automotive paint shop.

Thanks
You can just use a exacto blade and scrape the paint off but i flew it and did not notice any more heat on the painted motors.

how do you connect the external booster? do you simply replace the wire antenna with an sma connector?

Sure, will try to get some pics of the WLToys booster mod up shortly.

Yep, that's it. You just need to get signal from the internal stock antenna, out to the input of the booster. I'd already upgraded my Hubsan Tx with an A7105-500 module, so the RP-SMA pigtail on mine is connected to it's antenna out. The stock Hubsan Tx has a PCB antenna that's driven by an A7105 that outputs only 1mW. There's a small chance it may not be enough to drive the Sunhans booster input. If the Sunhans' blue LED blinks when you power it and the Hubsan radio up, then it's working.

Beside connecting the RP-SMA pigtail center signal wire to the Hubsan Tx antenna trace, be sure to also connect the pigtail's shield wire to the Tx ground somewhere.

*While it's ok to power on the Sunhans with no signal at it's input, always be sure an antenna is attached to the booster's output or it'll burn up. I'd also recommend powering up the Sunhans first, or at least at the same time as the Hubsan or WLToys Tx, so you're not applying signal at the booster's input while it's off.
