Do you do anything special to get the existing silicon off the connections prior to heating up the connections?

Hey rdlohr you should take some pics and post your wire shortening process!! If you have the time and patience.

Remember when flying inverted that down is up and up is EXPENSIVE!

LOL! I'm holding my breath and you want me to take pictures... My soldering iron died. I used it just last week. So I took out my camera to capture what I'm doing, and you guessed it, batteries too low. OK, I know when the big guy upstairs is trying to tell me something. Time for bed. Tomorrow, I'll go at it and take some pics along the way.

looks like you got some wierd looking servo link geometry going on there, like in the shot of the left side, I think you have positioned the servo upside down, the horn is supposed to be at the same height as the bellcrank for the swash....
Yeah, I dont like it too much myself but as Ozydego sais it is to clear the canopy. The geometry is fine and it doesnt bind, just wish Align would make a canopy that actually fits.

Good luck tomorrow rdlohr

On the tiny tiny solder joints, I use my cold soldering tool. I got mine from radioshack and got the conical tip. it is much smaller and more precise than my big'ole 150watt gun. If they have silicon over the connections, I usually just scrape through it, once you get to some bare solder, the rest will dissolve away with the heat from underneath... As for the strain relief, I just make sure to put it on my new set of wires before soldering the new connections, I have had to take them back off more than once to put that dang strain relief back on Rdlohr... I feel for ya I pull out my SMT LED's every now and then and make light tracks, and the whole LED is 1mm by 2mm, so you can imagine how small those connections are... the cold soldering tool does help, because it also doesn't heat up the surrounding components...

But Honey, I can't live with just stock.....

Since I need a new iron anyhow, maybe I'll try the Radio Shack cold soldering special. I had a trusty 18 watt iron with a very fine tip that I'd been using a long time, but I guess it had to go sometime. It cracked me up that it went just before I was about to solder the first thing that has made me nervous in years!

I hear ya on the strain releif. I used to solder on the big CB coax connectors which took about 5 minutes to heat, then to find out that I had left of the outer casing and had to start from scratch!

Thanks for all the help guys! Tonite I do it!

Well, my Cold Heat iron didn't work too well After buying good irons for my employees I can't believe I ever used a Radio Shack soldering iron. Actually, those would be ok with a good steel tip ...

I opted for the dual power solder station from Radio Shack. It has a decent tip and for $21 I can use it for both light and medium duty work. The cold iron with conical tip was $30 and I didn't get it because I didn't want to chance using a new type of iron on something this critical.

Whoever said "This takes patience" said a mouthful. I wired three servos and am very happy with the results. Had to use a magnifying glass to check my work. This stuff is small! That having been said, I would NOT recommend anyone try this who isn't already pretty good with an iron. Its easy to overheat things, and easy to run two pads together by accident.

Having done all this just for cosmetic reasons, I can officially be considered ANAL! Oh well, it looks damn nice.

Next I have to do the last servo and the gyro. I've been taking pictures so detailed posts are coming.

Here is how to do it. It took the opurtunity of having bare ended wires to put on the nice black braid too. I put a piece of heat shrink on the ends to finish it off.

I'll post the gryro pictures after I do it.

For sure man, I do all my helis this way, takes me freaking hours to do all the wires nice, loom and heatshrink etc.. The end result looks very clean and makes a person feel better about the build. At least for me it does, I like taking pride in tidyness and so fourth.

Sliick looking... I knew ya could do it Sux tho dont it... What we do for our helis. Personally, I didnt open my gyro to solder new ends in, I cut them from the other side and made new ends... Good luck, as I have not seen the electronics inside the 401.. who knows you might inspire me

But Honey, I can't live with just stock.....

Home depot has the cold soldering iron as well. But for like 50 bucks, you can get the black and decker iron with adjustable temperature, only problem is you only get 500 or 900 degrees. I usually solder around 700 degrees but unfortunately my soldering station is discontinued so tips are hard to find. As far as the pads running together, you can use a dvm to test that and keep some solder wick on hand to clean things up. Thats how I did my pinball circuit boards.
