RE: Eindecker EIII
 

My Futaba book on my 7C says to place the antennas as far away as possible from each other and at 90 degrees to each other. The picture shows one antenna on the side of a fuselage and the other across a bulkhead ( neither one being vertical)......another picture shows a heli and a similar arrangement as my installation.

When it comes down to it - there are only 2 antennas and they will always be on the same plane relative to the receiver - what you are talking about is relative to the model. And that is where the debate lies........

Another consideration is surrounding metal such as what the front of this model will have totally enclosing it and also the big metal power plant up front which can block the signal if the receiver is too close to the front of the plane. And then there are all the flying and landing wires, not to mention the squirrel cage of a landing gear.
Oh, and don't forget the three pairs of control cables going to the tail surfaces.

An interesting conversation, isn't it?

RE: Eindecker EIII
 

It is an interesting conversation. I wish I could remember where I was informed about this antenna setup. It was included in a test of range strength compared to a 2.4 JR radio. If in the plane diagram the antennae are placed 90 degrees to each other and one of the antenna are not placed on the intersection line of the two planes then they can never be on the same plane regardless of how you turn the plane. We can continue this conversation this weekend. In the meantime I am going to try to find the article or video where this was discussed. Seems to me that is was a few years ago.

RE: Eindecker EIII
 

I would imagine that what matters are the planes of the antennas relative to the transmitter on the ground.

RE: Eindecker EIII
 

Oh yeah.........a real "cliff hanger"!












HPA

RE: Eindecker EIII
 

Yes, you are absolutely correct. From what I had read, my understanding was that the purpose of 2 antennae were so that they can be placed on different planes and the tests they ran showed the signal was more secure in this scenario. I don't even remember if it was a Futaba report. I will continue to see if I can find this report or whatever it was I read.

Hang in there HPA this is going to be riveting!!!!

RE: Eindecker EIII
 

tevens55 is correct on placement of the antennae. 1 pointing up or down, the other pointing out either side of the model, although I prefer the second to point fore or aft.

the latest from futaba is now to wrap the receiver in 1" of foam, like we used to do.

RE: Eindecker EIII
 

That's all well and good.....however, I seldom fly straight and level, so my antennas are always changing position relative to the transmitter.

What it all boils down to is the fact that there are two antennas and they should be spaced as far from each other as possible. The reason for two antennas in the first place is because the 2.4 wave length is very short (look at your own receiver) and to prohibit signal blocking from the model itself (engine, batteries, cowls etc.) a redundant antenna system was devised.

If antenna placement were as critical as some of us think, there would be a continuing problem with signal loss and subsequent crash after crash after crash. And that is just not happening!

That's my story and I'm sticking to it!

RE: Eindecker EIII
 

I got the landing gear from Larry........there was a problem with the fellow who was making the gear and fitting the cowls........long story short, he is history and Larry is looking for another fabricator.

Anywhoooooo, I got the first gear mounted to the fuselage. I had to hammer on it some to get it to fit (like I said, there was a problem). I also fitted the tail skid and added the wings. Now it looks like an airplane!

Now I'm in the home stretch. Time to add all the wires and cables.

Here are some pictures as it now sits..... oh yeah, still need to paint the wing, too.......and add the national markings on the fuselage sides.

RE: Eindecker EIII
 

I like your "brass blade" you have in your tail skid.........I did not do that on mine because I thought it would cause too much side load on the mounts..........because of the length of the fuse....there's a little bit of weight back there.

WTH.....who am I to give advice to MR EINDECKER!:):)
You were flying Eindeckers back in the day when most of the people (like myself) thought eindecker was some kind of lunch meat sandwich!:eek:

HPA

RE: Eindecker EIII
 

WhadoIno.....?

I had something very similar on my old Eindecker and it seemed to work fine.......I flew that plane for nearly 7 seasons.
It was kind of fun watching it plow up the sod!

RE: Eindecker EIII
 

I don't know how it is for you boys flying off those sweet mid-western grass fields, but on my field, if I didn't have a bit of metal on the end of my skid, I'd have to be replacing the skid every couple of months.

RE: Eindecker EIII
 

Well, there's that too.......I replaced the blade at least twice during that time. Hard surface runways are very hard on tail skids. Just punch out the brass rods, replace the old blade and peen it back into skid.

RE: Eindecker EIII
 

Turtle Report:

I finally started on the rigging. I have the front landing wires cut and fit on both wing panels.
There are 30 landing, flying, control and rigging wires/cables on this model.

Remember at the beginning of this thread? I was a little giddy because this design wasn't supposed to need the flying/landing wires........it was (for me) to be a quick and easy to assemble every day kind of flyer........

Who am I kidding? I wouldn't have flown it more than a couple of times before I decided to put all the wires on it anyway :eek:

It certainly looks a lot better with than without the wires!

RE: Eindecker EIII
 

An eindecker without wires is like a triplane with two wings.

RE: Eindecker EIII
 

Art and anyone else,

Attached are pages from McMaster-Carr of their wire and sleeves and also what you can order from Vogelsang.
How do these wires compare to each other and to what Balsa USA sells.

Art,

I see that you are using the rigging couplers, What diameter wire are you using.
I would like to use the 3/64" wire for all of the rigging and pull/pull cables.

Larry
(The Snail)

RE: Eindecker EIII
 

I have several coils of Balsa USA 3/64 cables - their third scale wire. The one I am using with the rigging couplers is less flexible than the other wires and fits through the hole in the coupler without any problem; however, the other wires are more flexible and goes through the hole with great difficulty.

I don't have enough rigging couplers to finish the flying/landing wires, not to mention the pull-pull cables for rudder and elevators. I also don't have enough of the easy fitting cables to finish the flying wires. I guess I will go to the solder on threaded couplers to finish the flying wires.

I like the look of the rigging couplers much better than the solder on threaded couplers......but they won't show on the flying wires which attach under the wing.
Plus they are much easier to install - no soldering - just crimp and go!

RE: Eindecker EIII
 

Look at this sweet ass cowling! Bling..Bling!

Ready foe pick up

RE: Eindecker EIII
 

WOW! That looks terrific, you are definitely my Hero! (does the dummy engine come with it?)

RE: Eindecker EIII
 

UUUUUUUMMMMMMMMM.................................. ........................NO!

RE: Eindecker EIII
 

Maybe no dummy engine (yet), but my good friend, Paul, did come through with some excess rigging couplers and Sullivan clevises. THANK YOU.

Just curious, but where did these couplers come from - Vogelsang or Teus? They have a greater thickness at the hole where the cable attaches - much more substantial than a Dubro rigging coupler. I like these much better.

some pictures to follow:

I put in the drag wires for the king post.......

For attaching the flying and landing cables I made long bolts by soldering nuts onto 4-40 all thread which will fit all the way through the wing and then use nylon insert lock nuts on the bottom of the wing to hold on the flying cables......I am still in the process of fitting the rest of the cables for the wing.

RE: Eindecker EIII
 

Here is a good shot of the rigging coupler I got from HorsePowerAviation compared to the coupler that Dubro offers.

Very big difference! Keep in mind that they are both 4-40 thread size.......

RE: Eindecker EIII
 

The landing gear saga continues.

After being unable to find someone locally that was interested, able or even understood what I wanted, I have taken the plunge and started to make my own gear.
I acquired a wire bender from Micro-Mark tools that seems to do the job. I ordered 1/4" and 3/16" music wire from Tower Hobbies and got some Sta-Brite silver solder to
do the soldering.

I started the process by doing a detail plan view of the front section of the gear and the rear v-shaped section and then plotted them at full scale.
I then took each of the pieces that are bent and laser cut some 1/8" birch plywood to use as a jig so I could check the shapes as I was doing the bending.

This seemed to work pretty well and I know that I would not want to do this without this jig.

Next I need to cut the flat pieces out of sheet stock, using the cut outs from the jig.
Attached are photos of the progress so far.

I don't like working with metal and this part of the project, to me, is a royal PITA.

Larry

RE: Eindecker EIII
 

Looks like you are making pretty good progress on your landing gear, Larry.......lots of soldering to get through before you're finished.

TURTLE REPORT:

I now have all the landing and flying wires completed, installed and adjusted........

Next on the list of 20 plus items.......pull the wings off - clean up the shop - then remove the landing gear and clean them up and add the brace wires.......notch the axel so the wheel collar set screws stay in place - then on to the tail, finishing up the tail skid and tail skid braces, hinging the elevators and rudder - then add the control cables to same.

.........and on and on it goes - the goal is to enter Fun Scale with this plane at the Scale Nationals (12, 13 & 14 July) - that's just around the corner.

Me and Larry are going head to head, er, make that Plane to Plane.......

Later.

RE: Eindecker EIII
 

WOOOO WHOOOOO!

I JUST GOT A MYSTERIOUS PHONE CALL! ......... ok, just settle down a bit......... breathe in - breathe out.......ahhhhhh, that's better.

to make a long story short - I just got a visit from the airplane fairy! at least, I think that's who it was..........must have been.

back to the phone call, Hello Art here - who? Horse Power Aviation........why ain't I in the shop and why isn't the cowl mounted..........


well, the cowl is in Cinciny, right? No, what do you mean NO!

What ! In my shop? really? REALLY!

I go out there and bada boom bada bing, there it is in all it's bling!


WOW, he must be magic, right? I would have seen a mere mortal - but I didn't see him.


This is all that I saw........

RE: Eindecker EIII
 

I'm thinkin' that if I leave it alone tonight, then when I wake up in the morning it will be fitted to the airplane, along with the motor and all the other stuff it needs for the maiden! :D

RE: Eindecker EIII
 

But (there's always a but!)......... but if that doesn't happen then I have composed a list of the count down items to completion. Periodically I make a list because I sometimes forget what I'm doing and this serves as a good reminder for me. I don't have "mount the cowl" on the list yet as I am still hopeful the fairy will stop by tonight and at least do that for me.[8D]

RE: Eindecker EIII
 

Whats #5?

RE: Eindecker EIII
 

# 22 Fly THE PLANE! :D

Jim

RE: Eindecker EIII
 

by the time I get to #22 Fly the plane........there will be another 15 or 16 items that need some kind of attention before I can fly it.

RE: Eindecker EIII
 

#5 Cowl ring...........you know, the place where the cowl mounts........that ring of plywood around the firewall.......because the cowl is heavy (mine weighs 2 lbs 2 oz) I want to epoxy on an additional 1/2" layer of plywood all around for the cowl to rest on and the screws to screw into.

RE: Eindecker EIII
 

:eek::eek::eek:Man your pig is going to be heavy....................

RE: Eindecker EIII
 

No, that's not heavy......that's called balance![8D]

RE: Eindecker EIII
 

This is the cowl ring.......now a double thickness......1 full inch.......

RE: Eindecker EIII
 

HPA finally does something nice and Art calls him a fairy. Tsk Tsk

RE: Eindecker EIII

But only in the most positive sense of the word.........like, well like Santa Claus.......he is a person of unusual abilities, nay I say SUPER abilities.....and special traits.........and it just don't get much better than that!

Luv ya, DJ

BACK TO THE BUILD

Turtle Report:

I got a couple of things done this evening, but I can't quite remember what it was.......:eek:

......let me look at the list [:-]- oh ya, the tail skid is glued, bolted and bungeed and the axels have a slight groove (made with the Dremel cut off disk). The set screw engages that groove - the loc tite keeps the set screw in place and my wheels don't fall off on the maiden flight (do you hear me Barry?)

The maiden might be sometime over the 4th of July weekend - Sir Percy, is there a convenient time and place for a video?
