Scratch Building Your Own RC Planes - Episode #10.5 Making Servo Lead Extensions

- Building your own servo lead extensions is a great way to save money and lower the potential of failure. You can control the quality of your leads for much less money.
I finally found a receipt from another supplier that I really like. This is where I get the 90 strand wire in bulk.

Mike, It is a pleasure to be along for the ride, watching you build and develop planes and techniques in pursuit of precision and reliability. thank you for sharing your knowledge gained and passion for the hobby. BTW, I like your shop!

Thanks Brad!!!
I am filming another episode this weekend showing how to replace a broken fuse. Lol.
It should be out next week.
Im glad you're enjoying the series.
Very pro. I was expecting soldering. Nice crimping.
Thanks Mike and the one's who add constructive comments. Very instructive and was worth to watch. I like the way you explain with calm .
As usual you give expert instructions and commentary on the subject matter. I'm a retired electrician so I understand missing strands and over crimped connections. Both of which leads to failures over time. Thanks again for a great video, Mike Seitz.
Thanks Mike. It's a shame we don't have more guys building their own leads; it's so easy. Maybe this will inspire some to try it.
Nicely done and explained, so that it isn't boring.
I like that.
Thanks. That means a lot. Don't forget to subscribe. It helps in the rankings more than you think.
Very nice video, I have been making my own extensions for some time and I always look to get different ways of doing things. Really enjoy videos. Thanks
Just some things I have found. the plastic end pieces are not designed for 20 gage wire. 22 gage i a lot easier. Martin Pickering has a video in which he also pre-crimps the spade were it grabs the casing. Definitely makes the job easier. A graduated stripper really helps to avoid cutting the strands. Lastly, most quality spades are gold plated, which inhibits corrosion. Great video. Thank you for posting.
the video is very good. thanks
Glad you liked it!
As a suggestion, you can put both wires in the end of a cordless drill, holder the other end with a pair of pliers and then turn on the drill to get a nice twisted, consistent pair. This is an old tube guitar amp build tip...cheers and thanks for the videos...
Yeah, I do that pretty regularly with 2 wire twist. It won't braid 3 wire though.
A very small "blade" jewelers screwdriver is also helpful to push in a "sticky" pin into the housing.
Good point. A lot safer too.
Hard to believe a year has gone by already
Mike, One of your servo extension cables on the video was made with the white wire in the wrong position. The white wire was inserted in the center position where the red wire should be.
Nice pick-up :)
Lol. I'll check that. Thanks.
Sure enough! Very impressive attention to detail. That would have smoked a $100 MSK777A+ in a millisecond. You get extra credit!!!
@@mikencrcf6018 It's always nice to have several hundred people checking your work. Positive feedback. Thank you for your videos.
I enjoy your channel!
I appreciate that! I should have the wing filming finished up tomorrow and then, we will start on the tail feathers.
useful video, whar is the brand a model of crimper you are using? thanks!!
Dissimilar metals in contact with each other will loosen with temperature change as the coefficients of thermal expansion of the metals is different. The reactivity of the metals being different will accelerate corrosion (even faster if there is voltage present). In short, crimped connections WILL FAIL eventually.
It takes one second per connection to hit those crimped places with a soldering iron. Soldered connections don't fail.
I agree with everything you add here and you're right, a correctly soldered connection will not fail.
However, there is a reason I (we) crimp rather than solder in this application.
I do solder all of my larger battery leads and I solder my switches and lights. However, I have to support all of those wires to avoid failure with shrink tube or epoxy. All of my switches get epoxy that is made just for that purpose.
Larger battery leads are supported by heat shrink to help prevent vibration at the solder joint. In addition, the larger wire is less susceptible to vibration failure although it does ocurr.
I don't worry about the solder failing but I do not want the wire failing just off of the joint. As you know, that is highest risk area on CORRECTLY done soldering connections. Since the molecular structure of the heated wire has changed and is weakened, soldered joints need support a few millimeters from the heated region to be safe. That's not practical in my opinion in this application.
If a crimped connection is done correctly, it will outlive several airframes. I've never seen one suffer corrosive damage in a plane that was stored properly but your statement is absolutely correct.
Thanks for the input and the valid points. It's nice to see guys who know a thing or two about the topics involved.
I've got 28 cables to make. That's 56 ends, or 168 female crimps to do. Ugh. Watching your video beforehand in mental preparation of starting the task...
Lol. Take your time. I'd do it over a few nights. No beer until after your done. Good luck!!!!
Where do get the pins and the plastic fittings for Sepkrum brand connecttors?
All so the cripping tool you use?
Where do get your balsa shetting, I'm trying to find 1/4"x 4" -‐48" long for a 60 size big srick. The plan set i bought calls fot 1/4"×4"-43" sides. But i have an orginal Great Planes 60 size abigastick, it uses to sheets of 1/8"ply (3ply)-43" long.
I think the doubled up ply sheeting would be stonger if not a litter liter. Any help would be appreciated Mike Seitz. You probably already know that all the great planes are all discontinued now. What same great product gone.
That's a lot to answer here. I will paste this question to the Facebook group RC Foam Core Wings and answer there where discussion is much easier.. see you there. In addition, I'll put links on the "Resources" page on the website rcfoamcorewings.com. that will take a few days as I am out of town.
And remember, if you haven't subscribed to the you tube channel yet, please do that. It really helps.
@@mikencrcf6018hello Mike.
No hurry on any of these questions. I kinda got carried away. I supscribed quite awow ago I'm sure i did. But I'll check a d see. Thanks for all your videos and infoe. Mike Seitz.
Metric not used by england and the usa ... the rest of the world uses it ... be about time if they joined the rest of the world and stopped making stuff that has no basis in actual measures beyond the length of some person arm ..
.
and still with the full volume power tools ... MUTE the bloody things ... after 3 video's one gets a headache listening to essentially nails scratching a chalk board ... SUPER ANNOYING and costs you likes and subscribers simply because you didnt have the courtesy to soften the over powering grating of your tools
for those mini connectors ALWAYS tin your wire ... to keep the strands in and ensure a good contact at all times ... NEVER do them without tinning ... thats how highschool students start until they learn the proper way to wire connectors ... ALWAYS tin stripped wire ends ... NO EXCEPTIONS EVER.
@@0623kaboom the purpose of these connector types is not to tin. Tinning creates an annealed portion of wire at the tinned area that is susceptible to vibration fatigue. Due to the constant vibration, failure is reduced to acceptable levels by this connection type.
