I will call tomorrow but I have already decided to fill them. This wing has some hours on it and I don't see and cracking of any kind. I might put a backing strip on it all the same and go up a bolt length. If I rivet it on and get it nice and centered I think I'll be good. I have a bunch of wiring done Jereme...I don't have pictures yet. I have realized that if you buy premade cables they have outer insulation and they seem pretty sano.

Can't wait to see some pics man! I'm about to upload some progress myself. I've been hittin it hard lately so I can hang the engine soon.

I really liked the premade stuff that just had the black finger trap stuff on it (I think I got em from Stein). The Dynon cables with the white insulation on the other hand... I hated that stuff! Difficult to work with.

Keep pluggin away man, I was thinking about your progress lately as we haven't talked on the phone for awhile.

So I have two of these and hope to figure out an adequate wiring plan for these and the rest of the plane...with some help...

I am going to be in uncharted territory on this plane so I hope to find some sound advice.

So I have a bit of work done. I have been trying to get a handle on the wiring and John Bright set me up! Without John and B. Knuckles my plane would not get off the ground. It became clear that my rudementary electrical skills were woefully inadequate.

But I am learning SO much, it is awesome!

Trying to get something done and decided on mounting the engine bus here to get those wire lengths down to as close to 6" as possible.

I may still be a bit longer but not by much.

What is the unit with the heat sinks-----looks to be some kind of diode setup, but not one I have ever seen.

Looks like it could handle a bit of current. What are the specs?

DSS2x61-0045A Schottky diode mounted on a Wakefield 401K heat sink.

John is the horse's mouth on this one. And as usual, adds the .pdf's for good measure.

I am using John's complete wiring scheme as we have the same all-electric planes running the same components.
I was lost in wiring limbo until he came to my rescue. A full nod to Bob K. for his continuing work to help us newbies make our aircraft safe and fun!

I am building again after several months trying to figure out a good wiring plan!

More to come...

Got it, thanks for the info.

Looks more robust than the setup I am using, something out of the Aerolectric Connection.

Might have to switch mine out for this setup.

diode
 

Bob Nuckolls/Aeroelectric Connection shows using one leg of a silicone bridge rectifier. "NTE53016 or equal" is called out in his latest Z dwg, Z101 rev B, which is titled "Single Battery Dual Alternator with Dual Feeder Aux and Engine Buses". Z101 is the template from which I developed my schematic.

I chose to use a Schottky diode which at $16 is almost 3x the cost of the silicone diode but it's obviously still low cost. The Schottky drops about half as much voltage, approximately 1/2 versus 1 volt, so it makes about half as much heat. (voltage drop varies with current and junction temperature so you can't put a hard number on it) My calculations indicate the heat sink is conservatively large, overkill really, and in fact the silicone diode could be used.

The SDS dual EM-5-F four-cylinder system draws a little over 9 A at altitude and a little over 14 A with both fuel pumps on at low altitude so that gives an idea how much heat the diode generates.

I have been working on the wiring of the SDS system and modules

I have this mocked on relay that is for another spot, actual relay on plane.

Fuse stand etc
 

I am moving to the hangar early in the build, my spouse wants her garage back haha!

[IMG]IMAG1596 by Kent Luttrell, on Flickr[/IMG]

[IMG]IMAG1591 by Kent Luttrell, on Flickr[/IMG]

I whipped up a fuse transport deal and a control surface stand. I have several additional assemblies and am parsing through which ones will be used. All need work, some more than others. Vans has a few QB assemblies that need work and may be used depending on their condition relative to what I have on hand.

What's with the Stingrays? Collector items?

-Marc

That is a Stingray "Mini-Twin" tandem bike. Collector's item of my wife grandparents, they bought it back in '69 for the grandkids to ride when they came to visit. It is a single-speed bike from hades to ride.

Hangar
 

Quick shot of my hangar. Trying to get some pics uploaded but my phone is giving me fits...

Tail mounting
 

I have wanted to mount the HS for months but did not have room in my garage as it was partitioned for work stuff. Now I can get to it!

[IMG]IMAG1676 by Kent Luttrell, on Flickr[/IMG]

[IMG]IMAG1681 by Kent Luttrell, on Flickr[/IMG]

[IMG]IMAG1680 by Kent Luttrell, on Flickr[/IMG]

I have to do a bit more as the HS bars that it mounts to have been previously drilled. So off to the lathe to make a custom drill bushing so I can accurately get the holes drilled. The same goes for the front spar attach points.

Elevator stuff
 

I have started the elevator tip install and just need a bit higher temperatures to do the fiberglass work. Trimming and such to follow...

[IMG]IMAG1658 by Kent Luttrell, on Flickr[/IMG]

[IMG]IMAG1657 by Kent Luttrell, on Flickr[/IMG]

Sure is cold in this hangar...I may have to delete and/or add a rivet as I think I messed up the placement of the aft-most rivet here...oops

looking really good Kent! This is exactly where I am in my build, so I appreciate the pictures. Last night I drilled the holes in the elevator horns that attach them to the horizontal stab bearing.

Ryan

Thanks, Ryan! I have those up next after I get the HS mounted and sorted. We just have to keep at it and sooner or later we will be done!

I hope...HAHA

Heck ya man! Keep the ball rollin!

Thanks, Jereme! I am still rolling. I am not looking forward to the unbuilding of the right-wing before the building but...I will persevere!

By all means keep us informed. Your updates are worth the price of admission many times over!

-Marc

Good to see you still on it.

Thank you Marc! Sometimes when I trudge along alone in the cold these notes are truly an inspiration!

Thank you Blaine! Just got the other wing to start on and then I can concentrate on the wiring. A bit of odds and ends around the beast but it is coming along slow but sure.

Keep on keepin on Kent!

Thank you, John! I am at the hangar working on attaching the tailpieces...a little involved with finding the center of predrilled holes in tight spaces...
custom center finders being made.

HS mounted
 

Moving on to the VS, hope I can find all the parts...

Once again it has a HS!

torque stripe
 

Kentlik,
Good morning Looks like excellent work done on the HS. Please note that the proper use of torque stripe is from the fastner(nut, bolt head) to the base metal. If it is used in the nut to bolt this does not show you any rotation if the 2 rotate together. Keep up the great work.

Thank you!
Thanks for the tip on the torque goo! I put it on to tell myself I had torqued the nut. Frankly didn't think of the actual area to place it and it seemed like a good place to see if the nut was slipping off the bolt. Good to learn something new every day!

I actually have to remove the darn thing as I got ahead of myself and forgot to drill the other side of the elevator horn...oh well, reset the darn thing.

I haven't put her on the gear yet, I am vertically challenged and it is way easier to work on her when she is lower...

Looking good :)

Thank you, Mike! These last few steps have really helped to keep me slogging ahead.

Elevator horn drill
 

I got the horns accurately drilled last night. I made a jig as you would do normally to ensure the holes are straight and true. My horns were basically dead on and it was a push on which one was aft of the other.

I didn't have an aluminum block the correct dimension or the milling machine I sold last year to mill it so I stacked up material to get to the correct dimension. As it turns out the AL on the back worked well to ensure the last bit of transition to the second horn worked well and kept it nice and straight.

Heck ya man, that will work nice. My horns were certainly further off than yours although not nearly as bad as some others I have seen.

Thanks brother!
I was hard-pressed to figure out which one was aft. It turned out really a none event, the drilling.

Vertical stabilizer mounting
 

I moved on to the Vert. Stabilizer and found that getting this thing mounted and drilled to be quite a challenge, but one that I am up for.

Cut off a portion of the front spar but found I need to take a bit more off, about 0.185

Haven't drilled any holes in the new emp to mount it but have found the procedures to get it done.

Mounting Vert.
 

Well...this was about what I expected. Had to use the 90° drill head to get the holes started through the existing holes. I have done this before on other projects and have a few special tools to get it done correctly ie. drill bushes etc.
this one wasn't too bad as I could just get the tool square in both axis with the clamps on.

[IMG]intaft by Kent Luttrell, on Flickr[/IMG]

The bottom two will require another tool to manufacture. Just an extension for the 90° drill head.
