Red light.....Green light

[FlyingBlender]

Sorry, I was reminiscing about my childhood.
Well not exactly.

I saw a website and even a video with a Lama v3 that
had red and green blinking lights.

Anybody know where I could find them?
I have been to so many forums and websites while waiting for my
Esky to arrive I can't remember!
Also anyone know how much battery power it uses.
In other words how much less flying time one would have.
OR could one buy a larger capacity battery.

My Esky Lama v3 arrives today. Yeah!! :D

Thanks in advance.

Hi Robert are you talking about Navigation lights, I put a set on my Kyosho and I think they look great here is the link, see what you think :)

Thanks for the web address.
But the ones I saw were pretty simple.
Just one red and one green.

You can get flashing LEDs- which are in reality a timer chip and an LED in one case- from most electronic component hobby shops. You just wire them across the motor terminals ( if they dont flash, turn the LED around as they are polarity sensitive). If you run a battery of more than 5 volts, put a 2.1 ohm resistor in series with LED- it does not matter which wire you put it in.
The added power drain is next to nothing compared to motors so flying time would be affected very little. A guess would be you would lose something like 30 seconds of flying time for the LEDS at most.

By the way, flashing RED lights are anti collision lights, on helis usually fitted top and bottom for all round visibility. Red and green lights are constant intensity lights fitted left and right to aid other aircraft to working out if the aircraft is flying towards or away from them.

Hi Flying Blender,

I make my own! In any electronics store, you can buy red and green flashing LED's, but the port and starboard lights don't flash
for a red LED 2.1 v, 20mv powered from 4.8v I use a 150ohm res on the positive side. and for Green, 3.4v, 20mv I use a 82ohm res.
If you get them at 18 or 20,000mcd they will just about blind you!

This may not be what you are looking for but since this thread now becomes an LED and we start talking about it so I added a couple links for everybody info.

Thanh Tran one of our Tech Support team makes some of those http://www.rcgroups.com/gallery/showphoto.php?photo=15266&sort=1&cat=500&page=1

He shared his codes with others if you are technical enough to build it yourself. I am not that technical and cannot even solder properly. I bought a set from him and it working great. It is not only has navigational ligts but battery light alarm as well.

My MX400 with Thanh's strobe lights. You can see the navigational light on the skid.

Thanks very much for introduction to the thread Eddie. I really appreciate it.

Robert, you can get simple flashing LED from here:
http://www.allelectronics.com/cgi-bin/category/340200/Flashing.html

These are simple & cheap to use. You just need a resistor serialized with the LED and connect it to your battery. It will flash.

For more feature and strobe like looking lights, I did the lights for my helis. You could see Joe from rcgroup fit it on his Lama here:
http://www.tjtrc.com/videos/batman_copter.divx (in DIVX format). The lights on mine also act as lipo alarm to tell you when to land.

hi thanhTran :D
Took at look at your website and it is definately one to bookmark, I used to like making up circuits so I am going to give it a try.
I thought the batman copter was brilliant :D :D

[thanhTran]

Thanks Sue :).
The batman copter video was from a fun guy. How many helis have your helis bred already? :D

[The Broker]

Hi thanhTran :D
At this moment in time I own 1 Raptor 50 Titan (nitro)
1 Kyosho SR-K
1 Kyosho Concept EP
1 T-Rex 450XL (not finished yet)
1 Lama co-axial
1 Twister Bell 47co-axial
Its not my heli's that breed so much as my husbands and I can't list his it would take too long, there are heli's all over our house and they turn up in unexpected places like under the dining room table :lol: :lol:

Wow Sue your house must look like a fly-in.. :D I only have two heli's my old Shogun which is once again waiting for conical tail gears.(I gotta get a belt drive kit for that girl) and my Rexy SA (in progress) I do have a nitro plank - Stik 40 and a Tensor 4D - (just about finished) A Miss Hanger one flying Hydro..( tanked er nose first into the grass..not pretty) and a Blue Angels ducted fan jet..(still in the box will play when I'm REALLY bored)
Cheers! Sleepster... 8)

Sleepster you would not believe it, in our home we have 19 helis, 6 of them are nitros, and 13 electric and 2 kits waiting to be built.
When my husband goes to fly at the weekend they are lined up ready like dogs waiting to go for a walk, he always takes 3 sometimes 4 depends if I am going with him because he has to make room for mine.
When they come back from flying they stand in the hall till they have been checked and rubbed down (nitro) if they have had an accident they are immediatly stripped down to repair.
I am used to them being all over the place but it must seem weird to others not in the hobby. :lol: :lol:

[Sleepstalker]

OMG!!! :shock:

[G-MRM]

Lets me just say, accidents are rare..... this weekend it was engine failure, see my other post in Century Nitro !!

Today I took 5 helis with me, "2 Ravens, Sceadu, T-Rex 600 and The Brokers Rappy... Ha Ha.... Only a test flight to warm the engine and apply the after run oil while warm.

[thanhTran]

Must be fun & very busy taking care of all those helis. Now you give me some reasons to build one more heli ;) Thanks for showing the pic of your Kyosho SR-K. That sure looks awsome! I've been wanting to build a 500D Trex for a long time, but never got enough courage to start.

Want some real fun?
Hook up some nav lights and a nose mounted , white LED, the brighter the better, aimed at the ground at about 60 degrees down with respect to the helicopter.
The weight down some paper tape around your back yard.
The challange, try to follow the tape by keeping it inside the white LEDs beam while you fly around the backyard with no other lights on. It is so hard it is not funny.

I found I needed 3 LEDs on each skid ( I use 3mm 6000mCd ) to get enough visual references to fly and stay in control.
And that was on my Venom coaxial.
