Speaking of building, I'm still plugging away at my latest AR6400 build and ran into a problem I don't know how to solve...MY SERVO'S BEEPING!
When I plug in the left aileron servo(from a 4-Site) it beeps and won't move the aileron!
Help!

Check for debris in the gears. Make sure they turn smoothly and easily.

Hmm, an "open" servo eh? I have two, one is rough to turn, I think I got a tiny dot of glue on it. I know it is there, but I can't see it even with my magnifying desk lamp. I like the closed servos, and they can be just as light.
This one is less than $4, weighs 1.7 gram, and works for me:

But the plug isn't the one that fits 6400 bricks, it is the micro 1.25mm pitch, not a Spektrum RX style. It is not Micro JST.

Yea, that's a great site, I was able to identify all my connectors from that. He has great info, pictures, and prices.

Thanks Pete.

the connector they use on that is a molex connector made for: http://www.hobbyking.com/hobbyking/s...Receiver_.html
which is compatible with spektrum transmitters.

The ar6400 has 1mm pitch connectors. Those are 1.5 I think, and so they will fit the ar6300 (I don't own one).

I can measure them if someone needs the "pitch", just tell me.
That's the Rx I installed on my Snowball.

You need to be careful with those and move the wire on the servo frying end before you use it.

For someone who isn't a complete idiot, the price is right.

Beeping servo problem... battery lead length?

Identified the guilty culprit as the servo extension I used. Right and left servos both beeped and remained stationary when connected to this extension. Both worked normally when the extension was replaced.
Purchased it from Glenn at RC-connectors who offered to replace it if sent the suspect one back. I've had good luck with other orders from RC-connectors and great service from Glenn so I pulled the extensions from an older plane to get the new plane working and ordered some more from RC-connectors.
Glenn calls the plugs that fit the ar6400 and HH linear micro servos nano JST.

On another note, Does anyone know if increasing the length of the battery lead to the ar6400 by a couple of inches will create problems?

It shouldn't within reason.

I use the 6" HK battery entensions all the time.

Are you sure it wasn't a servo reverser?

Don't think so. Looked identical to the other extensions and I've only ordered extensions.

"Before there were helicopters, there was the Storch"

Here's the model that's been giving me the wiring grief. Waited to post until I'd gotten the wiring sorted and taxi tests completed in the basement. Got the tail up on one run before sanity took over!
It's a 'fairly' scale model of a WWII German Fieseler Storch. Chose it because it's so good looking (not)...actually it's another attempt to see how slow a scale micro can go indoors...so I started with an airplane that was designed to go slowly in the first place
So far, it's all 4-Site organs but with the size and weight of the model, I may be pushing the little 8.4mm brushed...
WS=33", weight so far 71g, calculated wing area approx 1 sq ft, so even if it puts on a few grams before I'm done, wing loading should still allow it to fly pretty slowly.
Interesting features include working landing gear(works the way the Storch's did I think, and sort of scale looking) using two ballpoint pen springs...I'm way oversprung. It takes a full pound to compress each spring completely...the model weighs less than 3oz! Only reason I didn't re-do the springs is I started with the landing gear and I'd have to dismantle the plane to change the springs!
Full length fixed wing slots (the Storch had these) It'll be interesting to see what these do (if anything).
Wikepedia shows a colour picture of Rommel's personal Storch while he was commanding German forces in N. Africa...it's white! so I'll probably just do all the brown camo squigglies with a brown sharpie.
I read a lot about Storches and if you're still reading all this babble of mine, I ran across a good true story involving a Storch. Apparently a Storch was the last aircraft "shot" down in a dogfight in Europe in WWII...by a Piper Cub! The American crew spotted the Storch below them and dived to attack, 45 service pistols blazing away out the window! In an attempt to evade the attack, the low flying Storch caught a wingtip and crashed injuring the crew. The Cub crew landed nearby and administered first aid!
It's been fun building this thing...now if I can get UNGN to tell me how to use the Xport to run the flaps while still using spoilerons, my Storch will only need a slight headwind to be able to "land backwards on an outhouse roof" (scale outhouse)
Maiden this weekend I hope.
Bill
