Hi Guys,

I understand there is a simulated afterburner light system available that surrounds the tailpipe . Does anyone know where I can find info on this system ? I may roll my own so it would be great to know the LED brightness etc...

Thanks,
Marc

Marc, I'm planning on using the LED's that Dreamworks R/C sells. It's a first for me, but I'll get there.

I can't seem to find it on DW's sight . Any chance of a link ?

No problem man.......you're welcome. Andy will make them in whatever size you want, just have to give him the dimensions.......on the 16 they are multi-staged. They are actually Luxeon Emmiters (as are all of Andy's lights, they are a lot brighter than the traditional LED and run on much lower voltage.) He will also make the controller box to whatever specs you want so that you can have the most realistic effect possible. Great guy to work with, have fun.......they definately are visible no matter what you're doing up there!

Take care,

Bryce

Wow ! Definately more involved than I thought . They look more orange than red . Very cool !

Mike, you porbably want them as white as possible. The afterburner should be a very light purple/white.

Go to DWRC, udner category/lighting and help yourself.

Thanks........they do look good. The orange hue on the nav's is due to me not dying the lenses red long enough on the 18......you kind of have to experiment with how much light you want visible when you are using lenses over luxeon emmitters because they are so bright! I had Andy give me burning kerosene color with the AB's because I'm experimenting with something else right now so I need as much light coming out of the tail as possible........otherwise, there are many different hues of emmitter to go with depending on how you want everything to look..........stay tuned......see if we can get some shockwave going on the next bird................

Hi Marc, here is Dreamworks link to the lights. I am also the dealer for South America. Very nice lights, also Luxeon emmiters. They are very bright and you can see them very well under the sun. We installed a set on an F-4 and we are know doing my F-4 an F-18 and a Hawk.

Thanks again guys but I don't see one listed as the "afterburner" on the DW site . Just lots of LEDs of various descriptions.

Sorry guys, really do need to get them up on the site... Will try to get this done sometime today. The afterburner rings are in stock, will take some better images and get them posted.... These are Luxeon emitter rings with module. By far, the brightest afterburner rings on the market. For the moment, any questions just give me a call.

Function: A basic current is applied plus an additional intermitting current showing the effect of a burning flame. Very impressive from some hundred yards of distance. The ring may be switched from the RC via separate switch or you may use it parallel to your throttle-channel. The switching point can be programmed at the electronic board.

I was just thinking about one of these yesterday!! what a conicidence.. I guess those rings are okay with what ever heat is back there??

Bryce Watson

My Feedback: (6)

It's not the heat coming from the tailpipe that you have to worry about..............its actually the heat generated from the luxeon emmiters. But it works and you can see them up as far as you want to fly........cool stuff for sure.

Todd, do they actually glow bright white or yellow-ish?

For the budget minded, I have under $5.00 in the ones I made for the F-16. Hooked into the nav lights.

Todd. i looked on your site and no info as of yet, i will look later

what is the price for the afterburner rings?

If I get one more IM on this...........

Ok.........I'll explain a few things here, I've spent the past three or so years trying to get this right.........and this is how far we've come but here is a bit of what I learned.

1. Luxeon Emmitters while extremely bright, generate a large amount of heat especially when you up the voltage on them. The first ones I used on my F-14 were white as you can see here. [link=http://www.rcuniverse.com/forum/m_4831267/mpage_10/key_afterburner/tm.htm]http://www.rcuniverse.com/forum/m_4831267/mpage_10/key_afterburner/tm.htm[/link]

they are the external rings outside of the F-15. I then ran the F-15 ones up by using a 6.0v battery instead of the 4.8 to make the ones inside the 15 appear just as bright...........but could only do this for a short time because of the heat and the fiberglass tailcones. The first F-14 used stainless steel tailcones built by Tam so I did'nt have to worry as much about heat. But with the F-15 and F-16 this was a different story as the tailcones are fiberglass..........so with the 15 I had to paint on BVM heatsheild and with the F-16 I had to flat out use BVM heat blanket because of the heat back there.........thankfully this all worked and its cool as the ambient air back there at full throttle and burner lights..........without the added insulation...........all bets are off because it WILL become very very warm fairly quickly (I timed it..........about 24 seconds) and you begin to feel the warmth thru the fiberglass.

2. Running the emmitters up in intensity also draws a considerable amount of battery life, and therefore you will need a lot larger battery in order for them to burn for anything more than one flight.............like 4000+ milliamps depending on how many emmitters you are using...........

3. Real afterburner light is largely dependant on the type of fuel that is being burned by the generating aircraft...........as a rule, generally the more highly refined the JP then the brighter the burn, now additives will also change the hues from orange, pure white, blue etc..........it really depends on what aircraft you are trying to simulate and what kind of fuel was being burned/engine type etc........at the time of the photo. (if your using a photo for your research)

So in a nutshell it comes down to this..................finding the balance between.......

What's safe ..................Are you going to cause a fire by trying to simulate fire? (believe me they get hot, especially if you start pushing the voltage up.)

Realism......does this look like what you would see in real life for the model you are flying? Staging the F-16 ring helps with keeping the heat level down as the highest intensity, current draw and heat generation is only at full throttle, which I do not fly at constantly otherwise I probably would have to charge the battery after every flight.

Length of light intensity...........How long you can get this effect for the amount of milliamps on board. (I charge a 2400 milliamp pack up on the F-16 every two flights...........anything more than that and the ring will eventually not light at all even though the battery is not dead. Now I could of course go to a larger battery pack, but then the question becomes........how much weight do I want to carry just to get the afterburner effect?

Everything in aviation is a balance folks...............this is no different.

Hope all of this info helps those of you out there interested in what has been accomplished thus far..............it took a lot of trial and error to get this far...........but with those lessons, we proceed even further. This is what we've learned thus far and provides a comfortable balance between all of the formentioned variables.

Good Luck

Bryce

Ok...
First, let me clarify.... Our AB rings are made from Super Bright SMT FlashLED bulbs, I realized I was in error earlier when I stated they where Luxeon Emitters. While most of the lighting products we carry are Luxeon, due to heat dissapation and costing, Flugmodellbau felt the could produce a better effect without the negatives by using SMT's. These rings do not generate ANY noticeable heat.

Well, as you can see from my attempts below, it is very difficult to take a picture of this AB Ring without it completely washing out the image. I had to reduce the battery to 4.8 from 6V and make some funky adjustments to the camera just to get these.
Our AB Rings use a very mild Amber bulb. In addition, the lighting module sends an intermittent current fluctuation enhancing the effect of a burning flame.

Technical info:

* Inner diameter 96mm, outer diameter 106mm
* Powersupply: 2s Lipo or 6V Nixx
* Power consumption approx. 1.2 Ampere

Pricing for the AB Rings is 199.00 although I am going to run an introductory sale on them for 179.00. Should have them up on the site shortly...
