Default LED STrobe

Just been for a spin on my motorbike and came across this in my local Maplins.
It's designed for auto styling use so is 12V but it will run (slower and dimmer ) on 7.4v

Weight is round 5g without wire, the LED is encapsulated in resin so it should be robust!

I've been wanting to fit a strobe on my Swift II Delta wing, so at 8 in wire and screws this seemed OK!

What a great find!! Looking right now to see if I can buy it in USA. I can only find links in the UK. Bright as the Sun! Thanks

have a good one

They look ideal CR!
Good price for 4 too, there are circuit diagrams on the net to build these LED strobes but sometimes it's better just to buy ready made

Can't wait to get it installed onthe Swift II, might give it a try tomorrow night!

If you can, try to get a video during the day and maybe at night if you can.
As bright as they are in that video in the first post. They are incredibly bright almost so that they would be visible during full sunlight, but pitch black would really be where they would "shine" LOL

....and yeah I like to buy ready made, tad easier.

Will do!
Fingers crossed the wind doesn't ruin things - it was very strong here earlier today.

Just got back from a little field just around the corner where I've been flying my UM P51, what a great little plane she is! Did a little damage to her trying too much too low (as usual) but now she's all fixed up and ready to fly again.
I am totally addicted to flying now, I can't believe it took me so long to find out. I had rc cars and boats when I was younger but no inclination to fly anything!
So glad I discovered Wattflyer too, what a great bunch of folks!

Default Flight report?

If you can, find a way to aim the Strobe at the plane, and not "out" from it. You'll have much better effect, and not go blind while controlling your investment.

Just me personally, I would if it was regular lights to show the wings better in the dark. But since they are strobes, (also depending on size) I plan to install on wings and use the controller to change to the corresponding wing color. Probably a clearance red or white strobe also on fuse, top or bottom have not decided which.

Default Re: LED STrobe

Finally got lights, incredibly bright, but a little heavier than I thought. For a 55" a/c shouldnt be too bad, as it is about 5 oz. cant wait too get it installed. Pretty confident that it can be seen very well in full sunlight.
Have a good one

Didn't realize you were going for daytime strobes. Still awaiting pics / vids

Like u said these will be mounted inside the fuse and upside down good idea still easy to see and orientation will be easy too

"It's designed for auto styling use so is 12V but it will run (slower and dimmer ) on 7.4v"

If you don't mind a little of diy you can use DC/DC converter and power it from basically any voltage source. converters have very high efficiency so there won't be much power lot in that.
it is not hard flying with any kind of strobo anyway?

There are a number of different ways to control an LED for flashing on and off. Something like a 555 timer available from Radio Shack, to using a little 8 pin microcontroller to do the same.

The 555's and those microcontrollers all will operate directly from the 5 volts available from your receiver power supply. With a transistor driver, one of these setups can operate a number of LED's in parallel.

If anyone is interested, I could lay out a wiring diagram for a 555 circuit using parts from Radio Shack, to be built on one of those Radio Shack general purpose perf board circuit boards. Places like www.digikey.com have a wide variety of LED's including superbright units.

Dennis that would be good, the 555 set up is a simple one. Change resistor values to change the the sequences, how easy is that! Would be a good one for folks to practice fairly precise soldering skills.


My old Slow V had a three bank 555 set up on it. Ran left/right wing and fuse lamps in sequence.


But anyhow, back to the original posting. I stumbled on a similar set at Advance Auto. 4 of the Super Bright square LED's, each has a domed clear cover. Comes with an adjustable board. Can adjust strobe speed, alternating or not, and on/off.

Set up to run off 12 volts, so perfect for a 3S lipo. I yanked the board out of the heavy metal box it comes in and it weighs next to nothing.

I got two sets of em. Was simple enough to color the lenses with a permanent marker to give me a red & green for wing tips, and a pair of whites.

Hi Glacier Girl
Did you want drawings on how to set up a 555 timer? (Looks like you've all ready been there, done that)

The 555 Timer is rated for up to 15 Volts DC, so it could run directly off of a 2 or 3 cell Lipo battery. It's also rated for a 200 Milliampere output. So, assuming a 3 cell LiPo battery, and approx 2 volts DC per LED, you can put about 5 LED's in series in a string. And at about 20 milliamperes each, you can put up to 10 separate strings on the thing.

There would be a little calculation involved for the series resistor required. If wattflyer readers are interested, I could put this info together. (Nothing a 5th grader can't handle!)

Dennis, go for it. Would be a nice reference for anyone wanting to do such a set up.

I run my set ups on parallel configurations. Little more involved, connecting resistors to each LED. But at least if one burns out, the rest of the string stays lit.

I usually run mine off an old single lipo cell.

A very simple single Led flasher can be made with a Lm3909 chip and a capacitor to run on as little as 1.2 volts. The chips are harder to find than the 555, but operate on lower voltage. I run them directly from the receiver off a spare channel (5v ?).

Just a note, the chip can run on low voltage, but it takes a minimum of 1.7 Volts DC to operate the LED. And, you've got to include what ever voltage drop takes place inside the LM3909. (Putting about 1.6 Volts DC or less on an LED will result in no illumination what ever. They stay dark.)

Running the LED and chip on 5 Volts DC with the proper series resistor should work just fine.
