Here is the details with pictures: http://www.rcgroups.com/forums/showt...8#post16580835

I am planning to make similar board for 737. Only instead of cool white LEDs use warm white for landing lights. They look more realistic. Cool white is too blue for lights but fine for strobes.
Great job on the lights Sergey, I know that took awhile to put together!

BTW, don't know if you've seen this but here's a link with different graphics for the 737. http://www.windrider.com.hk/product.asp?page=1&id=200

Can't wait to see yours fly!

Do you need programmed micro controller or whole thing on PCB board? I can program PICs quickly, there are couple blanks left.

There are several other requests for this board so I guess I can make a batch. Just need to order components and warm up soldering gun

Thanks for the quick response Sergey.
Yes, the whole module on PCB, soldered. In short, PLUG and PLAY. I can do the terminals, if it will make your life a lot easier.
I am not sure if you do this hand soldered (hope not). It may be a lot of work if not machine soldered, specially, if you have to make a few. So one piece, is OK too. Don't want to steal your free time. Of course, 2 would be SWEET!
What's the max load on the I/O. I'm thinking of 2-3WATT LED on the Wing Strobes, and the RED & GREEN NAVIGATION lights. Dealextreme.com in HK might have something good. I still have to check. The rest may be 1 Watt LEDs.
Thanks Again,
SPYRO

Spyro, I have five 1W strobes and 10 landing light regular LEDs. Strobes are no problem in terms of wattage. My guess five 3W strobes will work fine as long as they are strobes, not constant lights. For higher wattage it is easy to solder piece of copper foil to help transistors dissipate heat. It is also good to check if BEC can provide enough amps.

1W as regular lights may be too bright. At dusk they'll make plane look like one light ball. No airplane contours.

This one has it's contour. Sometimes, I fly it at 9 or 10 PM at high altitude. LOL, people from half to a mile, & talk about RC plane, would go, NO WAY, THAT WAS NOT YOU FLYING THAT PLANE!
I use one 3S, 2200 for everything. 5 min of fun.

Gentlemen!

My 737 is finally under way today, and I have been thinking a about a nose wheel issue... How and where is the steering servo intended to be placed?

Can some of you guys tha already have the kit give me a heads up on the issue?

That's A good question that we all have asked. Spyro suggested that we use a retract bay from the PKZ-P47 to secure the the retract unit itself. Now as for the servo location I myself am not sure yet as I will not start the assembly until the mid to late March. I will be watching this thread closely to see and learn other issue as we may encounter. GL

I have the kit but just wanna finish up some projects to clear some room to big this monster. Also I have a set of the new blue 68mm lander 4s 3500kv fans coming from DonsRC.

Yeah, that's the question. I am holding front wheel assembly for now

Ordered two sickle fans and two HET 3W motors yesterday. Will place order for servos today or tomorrow.

Meanwhile working on filling the foam with lightweight spackling and planning on flaps.

Servo mounting

How do you mount servos? Are you using glue or double sided tape?

Question for all! I have in these pictures my engine nacelle
(1)90mm for my 6'3 777
(1) 70mm from Mings 737
(1) 70mm form the A320 kit

Something does not seem right I am thinking that maybe the 737 is not exactly 70mm or the A320 is not 70mm any suggestion?

Sergey, If you're going in that direction...I have an extra bag of the "Drop Flap Hinges" if you need some.



Question: Is this EDF setup your using pretty efficient?
I'm looking for a 70mm EDF for my 2 meter GlobalHawk UAV that's not too power hungry.

Thanks
-Rick

btw...my Extreme A-10 w/ E-Retracts, Leading Edge Slats & Drop Flaps is nearly finished!

Based on the info Given by Ming:
http://www.rcgroups.com/forums/showthread.php?t=1218455

It would give the scale of the 737-700 to be around 18.54:1. 737-700 uses CFM56-7 fan. The fan diameter is 61inches, thus a scaled fan diameter should be 83.5mm.

Mmmm...

Thank you Rick! The set up with HET 3W on 4S is very efficient! But not very powerful. Just right power for scale 737 flight. Amp draw will be within 35Amp @ 450W average.
