I have been off work for the past 2 and 1//2 weeks from surgery. Seeing through the slits of my fat eyelids was no longer an option. Yesterday the eye doc cleared me to go back to work this Monday. I drive for a living these days and had to have a written clearance.

So I have been working on one plane or another off and on. Got some rib templates made for 2 different CL planes and rib templates for a new wing for my RC funny wing plane. And even made the ribs for it. Only left my DNA on the ribs maybe 6 times. Simply could not tell the template from the rib stock and way to stupid (and bored) to wait.

So I have templates rib templates made for a scratch build stunter of my own design. 12x50 inch wing.

But what I want to show you is the little trainer plane I Started on 2 days ago.
I have not flown a CL since sometime in the early 90s and thus feel the need to for a trainer that I am willing to loose.

I intend to blaspheme and put a 2.4 ghz radio on both trainer and the 50 inch stunter for throttle.

I was digging around on the shelve of a closet and found some forgotten parts, 2 stabalizers, one that was for twin engine RC plane and pretty decent size and the other come off an old slope glider and much smaller.

I like to re purpose things and after the light bulb came on in my head.

So what I have is the big stab is the wing for my little trainer. It was 8x20" so I added 2.5 inch tips to it for a 25 " wing. That gives me 200 square inches. Seems kind of right to me for a .10. The little stab is the stab. I used only stock I had on hand.

One fuse doubler (inside one) is epoxied on. And the engine bearers epoxied in, they are just spruce, and the fuse doublers are 1/8 lite ply. But I think that will be enough to hold that little motor. The fuse is 1/4 light balsa. The wing (old stab) is 1/4 inch stock that was framed up then sheeted with 1/16 sheet balsa. plenty strong for the wight. So the wing is is a 3/8 flate plate foil. But this is a trainer and dang near free so far.

I am real close to a major stop point now as I am out of building stuff. Used the last of my epoxy. And since I lost so much time from a pay check I can't buy more supplies till the end of the month. But I do what I can with what I have till then.

There are other projects I can on work some till then. So next month should see activity on several fronts.

Now I have no clue where around here I can fly the CLs when they are built. I will cross that bridge later.

Looks good.  After you fly 10 laps you will realize it comes back like riding a bicycle. I have no trouble after 20 years except inverted flying trips me up with the F2D combat stuff.  It is faster than my brain and reflexes.  Fun though. Then you will want to make the elevator three times the size like a Clown's. 

flyingagin

Thanks aspeed

The last time I I flew CL after a long break from it, I felt comfortable before the end of the first tank. Hopefully it will come be the same this. But I am a heck of a lot older this time. We will see.

I am going to increase the elevator but limit it's throw to start with. I want to be able to do basic manuvers with it.

I found a 3” bell crank In sever parts drawers. Yep several drawers. The parts add up to one complete 3” nylon bell rank. Since it is going to mount to the outside of the wing(8” chord) I think I will go with it. I can always seriously reduce the elevator throw, or crank it up later.

On a side note I have the ribs for the 50 inch stunter almost done. I need to tweak the spar slots a bit.

Ken

Went back to work, so all my projects slowed down. But I did get some down on this lttle guy.

Bell crank mount plates (1/8" light ply) have been added on both side of the wing. They butt up flush with the fuse (inboard edge), mounting on the inside wing. Bell crank and elebator control horn mounted.

Made my lead out guide. 2 brass tubes epoxied to a length of light ply. I will mount it with two screws thru 2 slots so as to have an adjustable leadout guide.

Put light spackling on the wing to fair in the bell crank mount plates and wing tips.

I have to buy a piece of piano wire to bend up some landing gear struts. I think 3/32" might be about right. Will have to get a pair of small wheels, maybe 1.5"?

I am thinking I will make 2 struts (opposite sides) and use nylon gear straps to hold them on. And have the top go halve into a brass tube that goes thru the fuse. Hard to explain but when I make the gear I will post a picture.

Ken

Edit
I found these on Brodak.http://brodak.com/control-line-parts...ding-gear.html

I started covering, I used some realy old off brand cote. So not a great job, but it will do. I pulled a dumb dumb and started with the iron to hot for this brand of cote, but I lowered the temp and the covering improved.

<o></o>

The stab is just placed in the fuse, not yet glued.

Ken
Well can't link or post pics

flyingagin

Let's try those pics again

Ken, it looks good. You're making faster progress than I am on my ".10" powered Cessna 177. (Enya .09-III is actually 0.098 ci.)

flyingagin

Thanks GG I ahve been following yourCessna 177

But I still have to make a handle. Sounds fast a simple, But I must be bain damage (breathed to much glow exaust maybe) as I never take the fast easy way.
I am going to mount a 2.4 TX on top of the handle with a romovable (quick change) line holder on front that will have adjustable line spacing and centering for the line. Yes 1 line that loops ftom top to bottom and back to the plane. the line holder front end will have the whole length of line (both up and down) from plane to handel. I am going with Spectra.
Will post on to night after work

Ken

I ordered the landing gear struts and the lead outs today.

flyingagin

I am going to do something like this for the handle. But have the front (the line part) interchangeable for different line sets. I will just use a single line that loops through the handle front and thus 2 ends at the plane. It will be a hard point handle front end(s)

GallopingGhostler

Nice looking solution there, Ken and neat work. Having throttle on it is a throwback to a friend's Testor P-26 with throttled .049 Wen Mac during the early 1970's. Had a third line on a ring slipped over the middle finger to control throttle.

flyingagin

Hi CG
I flew throttle set ups when I was young with a 3 line J Robert handle and bell crank. worked ok, And added that extra dimension of control, but also a lot of extra line drag and wight on the inboard side.

So this is kind of a throw back to that, but also a big step forward by getting rid of the extra line.

Sorry I did not mean to imply that the control handle pictured was mine. I found the pictures of that handle on another site and decided to file it future reference. I was just trying to show some thing of how I intend to make my handle. Again sorry for the confusion, I should have stated it was just a picture that I was going to emulate to a degree.

I apologize to any one I confused.

Ken

flyingagin

I used paint to show that I am going to make the front part of the handle removable. Quick change by using a uper and lower 1/4 20 stud and wing nuts along with a keying pin (so you can't put the lines on upside down) . That way one handle but indevidual line holders for each plane. Also at the end of fly I can just wrap the lines around the line holder for storage.

My landing gear struts and lead out cable came to day, but they will keep till the weekend.I am just to beat after work.

Also this morning before work I ordered the transmitter and battery I linked to above. It should be here friday. For the throttle servo I am going to use a Futaba s133.

I made some drawings of the handle construction, but they are more scribble than anything else. But when I build it I will post.

More this weekend.

II Test mounted the landing gear struts today. I still need to buy wheels.

I also epoxied the wing and stab in.<o></o>

That is all for today.<o></o>

The adjustable lead out guide still needs to be mounted, and the lead out cable made up.<o></o>

Now that the wing is epoxied in I can cover it.<o></o>

This weekend I will install the radio if my shipment arrives in time.<o></o>

At that point the plane itself is done I think.<o></o>

Then it is charge ahead on the 2.4 ghz handle.<o></o>

Ken<o></o>

flyingagin

The wing and stab are epoxied on now.
Still waiting for the radio.

Ken

GallopingGhostler

It's looking good, Ken.

flyingagin

All covering done. The red is some real old off brand (CRAP) stuff, A little screaming at it and it is an ok but not great cover job.

Next complete the controls.

Ken

GallopingGhostler

Seems about the same color of red as on my Ringmaster Jr. That is Hobby Shack Flitecoat, a low temp covering similar to Econokote. It was not the best stuff, but it was cost effective and still worked.

Anyway, plane looks fantastic. I'm sure it will be a good performer as a trainer.

flyingagin

Yeah I am sure you are correct. I used to live 10 minuts from a store. I did not remember it being such a pain. I think because what I have is so darn old that make it worse.

It is even worse to remove. Holy cow it is frustrating to remove.

Bu as a trainer I think you are right. It will do the job just fine. Particulary as I will be able to slow down and even land if I get dizzy. But it also should be able to do the basic round manuvers. That always helps to keep the noggin stable.

Ken

flyingagin

Het a question for you George

I have a little 2 ounce clunk tank. Think that is enough?

Ken

GallopingGhostler

2 oz. is definitely sufficient. I'm using a 2 oz. on my Ringmaster Jr. with an OS Max .15FP-S.

flyingagin

Cool then

Ken

flyingagin

I got a little more work done on the plane today.
