Topic: Ratray
I weighed my Rattray cowling and wheel pants a while back and didn't consider them heavy. I did have trouble getting the bottom half off until I modified it by cutting off the lower half sides and hinging them to the top half, That gave me access to the accessory section and bottom of the engine.
The cowl weighs less than 20 pounds, not counting the side fairing, but includes the aluminum hinges and stiffeners I added to the access panels and the automatic heat vents in the top half.

Thanks for the welcome. Thats fair enough, I have the glass on aluminum covered as I made my own boot out of glass and glassed it in. And the weight thing, Hmmm will have to weight it and see, but somehow I dont think I have a typical one as its not sprayed in glass. Its all a lay up and quality looks good. But I have not weighed it yet will see.

Topic: Ratray
Skeet,

Welcome back! The main argument against the Ratray cowl is that they were said to be heavy. My Herb Shable (sp?) fiberglas cowl weighs about 17 lbs., while my aluminum one weighs about 16 lbs. Also, some object to the glass on aluminum fairings on the boot cowl. As many of us know, Geogre Ratray was a boat buider and did much to introduce fiberglas to the world of aircraft.

Being experimental, run what YOU like. Keep us posted on the progress.

Am doing a rebuild on 7077J it had 160TT and I could not live with it any more. Has a 0320 a2d which I love cause I can run street gas in it (cheap) and is not IFR equipped (dont need that) so it is light and performs well on 150HP. But my question is seeing a few comments against Ratray cowlings I was wondering why? And dont just say there crap! Cause you cant verify that by me. I did fly with mine for 160 hours and found no problems with it. I could get the bottom off with out pulling the prop, and I actually like the looks. But I am open to discussion about pros and cons as I am doing a complete rebuild. So lets here it. Please be objective no bias on just what you THINK is best. And thanks for considering.

Thanks Rich,

It appears the weather will be in the 50s with mostly sunny skies and hoping for light winds.

Gauges - Engine gauges I bought are UMA brand and not a real saving there considering they're about $100+ (www.umainstruments.com). They are 1-1/4" dia. I returned the gauges to the manufacturer for installation of resistors to prevent excessive fluctuations which I discovered during initial Green Engine Run. These gauges are made to work with UMA or VDO made sensors. When making your order must specify which type sensor will be used for properly factory calibrated gauge.

Wing craddle - As I neared the time to begin with the wings fabrication and while on a trip to Home Depot Aircraft Supply Company, I came accross one of those decorative iron support for a house porch. Since it was only one, I managed to get it for somewhere in the area of $3-$7 (can't really remember. Anyway, cut it up and managed to clamp together what I though would be good wing craddles and had a friend weld it together for me. The intent was to have them mounted on a trailer for transporting the airplane with wings folded, but also turned out to be a good assemblies holding craddles. The white rotisery holding the finished wing was actually a portable garment rack from the same aircraft supply company for a $12 price tag which I olso modified using two 1/2" x 7' long pipes at bottom and one 1/2" x 8' pipe running through lightening holes in ribs. Strong enough that I was able to completely build all three wing assemblies.

Propeller - The prop was made by Clark Lydick of Patagonia, AR who at the time was in the process of selling, training and transfering his prop making business to Frank Johnson of Donie, TX. Clank had been in the business of making props for over twenty-five years and wanted to retire. Frank did a great job at finishing it up. Once Phase I on my airplane is completed, I will be taking it back to him with numbers for leading edge caps installation and final coating and finishing.

Another Gallery "Thorp Videos" is for members only, I'm not trying to discriminate but now that we have this capability I will start referencing Videos in "Tiger Tales". I know that there are several Thorp fans on the forum that have no interest in the newsletter, so we'll keep our content separate.

On another note, next week this forum will no longer exist. It will be replaced with a technically superior forum.

leewwalton 12/6/2011 06:31
Topic: From "About the Thorp"
I agree, I John is right on the "sum of the parts" making Thorp's design patentable.

As to the comments I made on the Flyers ... It was not the location of the pitch control (canard or aft) I was referring to but the actual mechanics of the original Flyers canard. If you look at it, it's hinged at the leading edge, like an horizontal tail/elevator without the non moving surface. My impression of a "Flying" surface is that it pivots at (or close to) the center of lift on the surface. The deflection comment was a bad choice of words, I of course realize that all surfaces on aircraft create lift. To me it looks like the Wright Brothers got lucky on the first flight and then changed the pitch control soon there after. Of course I'm out of my league aerodynamically here so forgive my novice observations/comments.

As to the patent though, if you read it it's not just the anti-servo tab that's patented. It's definitely the "all flying tail". I think both you and John nailed it, the "flying tail" you're used to on the fighters may not qualify as it is somewhat "cheating" with hydraulics rather than aerodynamics.

Beautilful looking ship ! Can't rush the WX ! Been there done that. Concernine the guages, I had that problem with a couple of gauges not being compatable with the senders. Trying to buy one guage and using another sendor to save a few bucks ! Not worth the time and effort. I went with the matched set and have not had any problems.

Looks like a "speed bird" and I am sure the test flight will be A-OK ! Lee would probably appreciate a detailed write up (and video) of the "happy event" for the next "Tiger Tales."

Topic: From "About the Thorp"
Lee,
Thanks for the link to the patent. I'm sure he developed his anti-servo trim system on his free time or Lockheed would've had something to say about that. Our time, our mney. John is right, the anti-servo system makes the airplane easier to fly and is essential in an open-loop flight control system such as on the Thorp. A closed-loop system, as in a hydraulically-actuated system on a modern fighter, doesn't need an anti-servo trim tab as John mentioned as the undesirable feature of an all-moving tail surface without an anti-servo trim system. The trim button in those aircraft changes the position of the control surface and there is no direct feedback to the pilot except through an artificail feel system.
The canards on the Wright airplanes are flying surfaces from an aerodynamic standpoint. It doesn't matter that the canards are out front versus a conventional layout. A horizontal stabilizer is a horizontal stabilizer regardless of where it is. I'm not sure why the Europeans are so infatuated with cnards on their fighters.
Also, an elevator on a hinged system doesn't just deflect air (I'm not sure if that's what you really meant). Moving the elevator changes the camber and angle-of-attack of a lifting surface which is the horizontal stabilizer/elevator combination. When the trailing edge of the elevator goes up, it produces negative lift on the tail surface, increases the angle-of-attack on the main wing and we know what happens then. Likewise, on the Wright designs, when the horzontal stabilizer changed angle-of-attack, lift increased or decreased on the surface.
Again, thanks for the answer. I was looking at just the all-moving hotizontal tail surface as a whole, which had been used before, and not thinking about the trim system that Thorp developed.

Topic: From "About the Thorp"
I'm sure you're right John/Spanky .. I was visualizing the canard on the original Flyers but come to think of it, the model B and laters did have a horizontal tail that could be argued "flew".
leewwalton 12/5/2011 21:09
Topic: From "About the Thorp"
I could be wrong, but I think, perhaps, that the Wright Flyers had elevators that were hinged somewhere near the center of the structure, & probably "floated", or "flew" also. Someone please correct me if that's wrong. Again, a major difference is the anti-servo tab & associated linkage, giving the desired "feel" & causing the deflected surface to return to the trimmed position. Brilliant.
Can you imagine flying a T-18 or any other all moving-tail equipped airplane without that basic characteristic?

jrevens 12/5/2011 20:48
Topic: From "About the Thorp"
Before I get in trouble for the Wright Brothers comment ...

My reasoning in that is that the canards on the Wright Brothers airplanes pivoted at the leading edge rather than at the center of lift (or near it). So they were not so much "flying" as deflecting air up and down (like an elevator).

... Just an observation.
leewwalton 12/5/2011 20:29
Topic: From "About the Thorp"
There are "flying tails", and then there are "flying tails". There were many Thorp designs before the T-18. I believe that what we're talking about is the modern stabilator with associated anti-servo tab, etc. No, it is not an urban legend.

jrevens 12/5/2011 20:27
Topic: From "About the Thorp"
Yes that is true. John Thorp patented the flying tail while he was at Lockheed, he left Lockheed in 1946. I guess you could make the Wright Brothers argument but that's might be stretch.

Here's a link to the patent

leewwalton 12/5/2011 20:25
Topic: From "About the Thorp"
Can anyone confirm that this is really true? "The T-18 incorporates the 'flying tail' which John Thorp held the patent for." Is this actually just urban legend? The flying tail has been around since the Wright Brothers. They used flying tails on all their aircraft until their 1914 Wright Model G. That was the first time they used a horizontal stabilizer with a hinged elevator. In fact, the G-model was the first aircraft to utilize a t-tail configuration. The Century-Series fighters such as the F-100,F-104 and F-105, developed in the early-to-late 1950s, had flying tails and flew well before the T-18. Just wondering.

Topic: Flight Ready

For the past three months I've been battleling what I presumed was electrical issues. Continually troubleshot and traced wires until I was begining to look like wires myself.

Last week the troubleshooting finally paid off. The problem I was having was on account of gauges not being compatable with the sensors I had in the airplane and engine. Shipping them back to manufacturer for recalibration cured most issues and now ready for first flight.

First flight was supposed to occur Saturday Dec 3, but for once in our lives the weather forcasters were right in their predictions and ended up with clouds on the ground for the past four days. When you want them to be right, they're wrong and when you want them to be wrong, they're right. Oh Well. N18DD once again ready for first flight and weather permitting, we should be in the air no later than Friday with monstly sunny day and hopufully light winds.

Will report after the grand event - and event I've been getting ready for well over fifteen years.

I see there have been only a few votes cast regarding the Fredericksburg Spring Fly-in. I voted for Jun 8-10 but am fine with any of the other dates. One thing to worry about in the Texas Hill Country during that time of year is thunderstorms. Those massive lines of growlers may be less likely in early June than in late April or May. Any date is a crapshoot though. The ealier in June we have it, the less likelyhood of excessive heat. July and August in Texas is just a struggle to survive.

Topic: tailspring
I bought a tailspring and tailwheel mech from Vans. I used a Lang wheel and tire, but replaced the old greaser bearings with a pair of heavy duty sealed double row ball-bearing bearings from McMaster Carr. Those bearings fit right into the Lang tailwheel. I made up a rear mount from 4130 heavy wall tubing which is very similar to those used on a Pitts and Tailwinds, but bolts right into the old flat spring braket holes. The front mount was machined from a block of aluminum, bored at the right angle and it too bolts into the flat spring front mount hole. Actually the rear mount was made to fit the angle determined by the front mount. Anyway it all can be seen in the picture. I can send some better pictures of the mount if you want. I have used this same setup on a Tailwind and a Pitts S1, and for me it works very well. Of course it is bascially the same spring and mech as what Vans uses on all those Oregon Cherokees (as my friend likes to call them).

Tailwheel. I would go with the Aviation Products tailwheel. Homebuilders "Special" in the Spruce catalog. Double fork and put it on a rod tail spring. If you need parts for the unit down the road, you can order them direct from AP in California. About $320.00 for the double fork unit. It is what I have along with the rod spring (not sure if there are anymore of them available...the rod spring that is). So far with 60 hours on the tailwheel...zero problems. Works as advertised.

Topic: tailspring
Hello Gang, I'm working on an older T-18 that I bought a few months ago. The tail wheel has a lot of play in it & I'm sure it needs to be re-worked. It's a Lang assembly. It Looks like the parts to re-work it will be about $300.00 from Spruce. I'm wondering if there is a better way to go, Vans, Matco etc. Does anyone have any experience with one verses the other? Does the longer spring of the newer style Vans type TW make the handling better? Is it worth the effort to re configure the system?
Thanks

Topic: Shims for Cleveland Brakes
Guys,

I replaced my brake pads this past week and noticed that there are two shims about 3/16" thick for each assembly. With the brake caliper piston fully compressed it occured to me that the total shim thickess was too thick. I replaced one shim with a 1/8" shim on each side along with slightly shorter bolts. My though logic was that with shorter bolts and less shim thickness the assembly would be stiffer and the piston supported better due to less protrusion from the caliper. Does anyone see any flaws in my logic or potential risks down the road?

Thanks,

Jim Mantyla

Now now Dick!

Surely you don't need a tubing bender to get 10 or so deg out of it. Worst case drill out the last few (10 or so) rivets on both sides, tweak the seat and then reset the rivets. The last few rivets will end up with some oblong holes, if that doesn't pass muster put some -5 s in there.

My seats (frames) came with the project and I suspect they were from Ken Knowles or Phil Tucker ? They are very light and fit well...except that the top of the seat does not rest against the top of the baggage compt. Rather than redo the seats I put a "stop" against the baggage compartment frame. The seat/s rest against the stop. I put a 0.50 doubler so the seats rest against the stop.

3/4 is standard (or at least typical) at this point.

The angle. .. My point was that a righter angle would lend itself to a taller pilot and a more obtuse and would lend itself to a shorter fella. As far as the reason, I'm sure you received an approximation from CSA. At this point you could out some "Williams" (as in Bill) and clamp the back to your bench or something solid and tweak another 10 deg out of it.
leewwalton 11/29/2011 06:55
Topic: Seats
Right! Mine are CSA kit seats with the hinged back.

90 degrees would be a right angle. 84 degrees is what the drawing calls for. ~70 degrees is what my seats are bent to. Consequently, the seat back contacts the rear frame in any seat position.

Unfortunately I didn't check the angle before I put them together. I can't think of any good reason for underbending the frame except maybe to relieve the stress on the light hinges, which are "undersized" because they used 3/4 tubing instead of the 1" called for in the drawing. Did I miss anything?
dickwolff 11/29/2011 06:30
Topic: Seats
Dick,
Most seats now are two part and most likely hinged. If yours are a single "L" shape then the advantage to a"righter" angle is allowing the seat to push back farther allowing more leg room.

These are "experimental" aircraft, the greatest variation between airplanes is usually in the cockpit.
leewwalton 11/29/2011 05:19
Topic: Seats
I just discovered that my purchased seat frames are 10 or 15 degrees underbent. Unfortunately they are now assembled.

Did I miss something in a newsletter? The drawing calls for 84 degrees. Is there some technical advantage to 75 degrees?

Here are a couple of shots of the flap motor install in the garage project. Oh and I took advantage of the last "warm" day of the year (apparently) and primed the rest of the airplane yesterday. May seem premature but I like to "seal in" the airplane before I start plumbing things, as usual it took about 3 weeks to get the thing ready to spray and 2 hours to actually get it coated.

Topic: Heat Treating
I used Hinderliter Heat Treating, 2005 Montgomery Street, Fort Worth, Texas 76107-4012. Phone: 817-737-6651.
This was back in 1996 for three individual gear legs, heat treated and stress relieved for $333.53.
I made them in two parts with a plate slightly larger diameter in the center of the "A" to be welded together later without affecting the heat treating.
I didn't have a hydraulic press so I used a hydraulic jack and heavy chain to straighten out the heat treatment distortion, bow and arrow style.

Find a spring shop that repairs heavy truck/tractor/trailer springs. Most will have a oven big enough. We have one here in Sacto, CA. I suspect many larger cities will have similar shops.

The gear Mike has is a later mod of the standard gear so it would fit in an oven. There is a drawing of this mod. I was there and helped move the plane, it is the old style gear. As for the new CSA gear "don't even go there".

5 year shelf life is what the guy at VIP told me when I said I had 20 year old unused mounts. Regarding the "time in use" issue not sure how that is calulated, other than during the annual you check them for cracking and any significant "sag" in the engine in relation to the cowl and or engine vibration/movement ?

Rather than risk a "new" 0-360 with 20 year old "unused" mounts, I sprung for the new rubber. "New rubber"...Priceless !

It sounds like you may have the CSA gear ? Mike made it in 3 pieces to make it easier to ship. The fact that you can take it apart should make it considerably easier to find an oven to heat treat it in.

Lord says 5 years. I didn't ask about "in service" life, but mine have to be 40 years old.

I've heard of comments on RV formums suggesting that Lord is the only way to go. All the others, apparently, are cheap immitations.

Gentelmen:
I am relevantly new to the Thorp world & this is my first letter to the forum.
I was lucky enought to become famous by bending the gear legs about 6" back & sliding down the runway on the spinner @ the Murry,Ky. fish fry.
Repair work is taking place.
The gear legs have been annealed, then strightened,the cracks have been welded & fish plate welded. I realize the inner leg is supposed to slide inside the outer tube. I could see the inner leg thru the crack in the outer tube & no crack appeared.I have no way of knowing for sure if the inner leg became somewhat attached to the outer leg in the welding process, what movement at that point had to be miniscule.
I am now looking for a heat treater that can handel the length of the legs.
My gear legs are diff. than the plans show, there may have been difficulty in finding a heat treater in the first place.
Picture the "A" frame being split vertical & a tab at the top bolted together. The horziontal tube in the "A" cut in the center with an inner tube about 15" long to slide inside each half with two bolts in each side.
Now I have two seperate legs that doesn't require as large an oven.
Does anyone know of a heat treater that can handel parts of this size? Help Help
Thank you Mike

Go to the Thorplist archieves and type in VIP and or engine mounts. It will have mucho info on the engine mounts. Be aware that the mounts have a cure date stamped on them and as such have a shelf life...according to the folks at VIP.

The Andair Valve, always heard good about that valve, never anything bad. Shutting off the fuel is probably always a good Idea, I should do the same, I afixed my shutoff so when the fuel is off it pokes me in the leg, most anoying but a good reminder. Its the little polished lever on the console below the mix knob. It is attatched to a piece of 1/2" 2024T3 tube that actuates the ball valve,the handle that comes on the ball valve can be modified to recieve the tube and a 3/8" socket universal to streighten things out......I will practic shutting off my fuel and see if I can depart from my laziness a bit....Dan
