Al,

I have more picture of Les' Recall PT-17, NC 48784, #137, if you need some. He just bought it and brought it to Creve Coeur Airport on the 5th of May 2007. It needed some minor maintenance, but that was attended to and was flown during the Fly In. The Staggerwing, NC 44G is also based here at CCA.

I've been adding stringers to my latest, and putting in the backer boards for the wing fillets. This problem that I'm still having with my computer is the pitts.....The chief guru says that he does not know when I'll have it back. I can't post any photos until I get it back online. Jay (damifino) and I have been talking about several ways to replicate the metal panels on the fuse, and I'm rethinking my idea of using real metal for the panels. We are also working on a more scalelike method of mounting the top wing and the Interplane attachments. This one will not use the stock interplanes, but will use interplanes that look like three seperate pieces.

Been reading the posts here, and maybe my suggestion will work for you. To replicate the metal parts on the Waco you may try using some aluminum flashing you can purchase in just about any hardware store, it is thin and it is strong. Also a hint as to the corrugated covering on the ailerons instead of pounding out litoplates, which by the way may also be used for metal parts Sig sell corrugated plastic for their Morrissey Bravo stock numbers SIGRPCP .010X8X17 $2.50 per sheet. SIGPPCP .010x6 1/2x13 1/2 $1.99 per sheet!

Hope this helps someone.

John,

I did consider the aluminum roof flashing, but I wanted to give the illusion of having metal plates without the possibility of all the metal to metal contact and the resulting RF problems that can creep in. I will probably use the old add primer in layers method for mine.

The SIG plastic from the morrissey kit is not a bad idea, but can you let me know what the spacing between the corrugations are? The Pica 1/5th kit uses 27 corrugations per aileron surface, and scale appears to need 34. Size of the corrugations would come into play as well, because if they are too large, they will stick out like a sore thumb. I suppose that I could build a mold, and pull them from fiberglass, and build the internals into the skins, rather than adding thin skins to a built-up balsa structure. It is not going to be a simple fix, I suppose. The spacing on the kit version is about 1/2", and for the corrugation to look scale, they need to be about .41". That is only 1/10" difference, but the apperance would be noticable.

Bill,

The only YMF to show up at the Fly In was NC 14081, a 1987 YMF Classic. Here are some photos of the Cabane and Interplane struts and fittings;

Pic. 1 – Cabane struts. A one piece unit. The round dot below the forward strut is a retractable foot peg for fueling.
Pic. 2 – Interplane struts, 3 pieces.
Pic. 3 – Top Forward fitting
Pic. 4 – Lower Forward fitting
Pic. 5 – Lower Rear fitting with aileron connection rod, note round shape.
Pic. 6 – Lower Forward fitting looking aft, typical of all other fittings.
Pic. 7 – Upper Rear fitting on QCF-2, NC 12428 (wing is upside down).
Pic. 8 – Lower Rear strut over fitting on UBF-2, NC 2091K (fitting is the similar to the QCF) note cleaner appearance than on the YMF.

The YMF fittings have the bolt going front to rear with the strut end between the fitting parts. The UBF and QCF have the strut end over the fitting with the bolts going side to side. The strut end (one end only, pic. 4) is adjustable on the forward and rear struts, not adjustable on the center strut on all the aircraft pictured.

John,

Yep, that's the look that I'm going for. It is actually going to be about as easy as the original kit form.

Bill and the rest,

Pica apparently got it wrong with the landing gear. The plans show the inner landing gear strut going from the center of the fuselage down to the axle, not so. The inner strut actually attaches above the axel to the upper section of the oleo as shown in the below pictures. The first is the Pica Subject plane NC 14031 in a photo from the Andy Heins collection on the National Waco Club site. The second is from a YMF Classic, N# unknown and the last 2 are from YMF Classic, NC 14081, belonging to Robin Williams of Michigan, who attended the AWC Fly In 2 weeks ago. The drawings by Paul Matt for the Historic Aviation Album have the landing gear drawn correctly. If some one has a picture of different gear on a YMF, I would be interested in seeing it. The gear on the newer Waco Supers is shorter but of similar design.

The guy in front of the red UPF-7 is Joe Norris, the pilot who took John and I for our rides. Helluva nice guy, and we gave him one of my Brotherhood T-shirts and made him an honorary Brother. He needs a number, Master Chief. John is in the front seat in one pic, getting ready for his flight.




Ken,

If you will take a look back at page #110, you will find that Joe has been awarded Brotherhood number 54. I only hope that he takes a look at this thread, and finds himself among those who truly love the old Ragbags. You are one fortunate man there Ken....It's becoming more and more difficult to find nice things to say about you. Do I sound jealous????? I am.

Hello Bill and Ken,

I have indeed found this thread and I really appreciate the kind words. I certainly enjoyed meeting Ken and John and Creve Coeur, and enjoyed having them along in the Waco. I feel honored to be a member of the Waco Brotherhood, and I'll wear my T-shirt proudly!

I am looking forward to following the thread and keeping up with what you folks are doing with your Waco models. From what I've seen so far, these are some impressive airplanes! If you ever have any questions about the "full scale" versions, I'd be happy to try to help.

Already looking forward to Creve Coeur next year!

Joe,

Welcome aboard and thanks for the flight. I think you will find there is an interest in all thing Waco, not just the YMF. For those who don't know Joe, he was kind enough to give Ken and I a ride in his UPF-7. He also has a little blog going at http://www.classicwaco.com/blog/ about his Waco. Enjoyed meeting you Joe and hope to see you again next year at Creve Coeur.

Joe! Good to hear from you, glad you found the forum. I intend to keep up with your blog, also, and will be posting my build of the UPF-7 here. It was interesting reading about your oil leak; when I first started riding motorcycles back in the 70's, I had a Triumph, known for not holding their oil very well. The old "repair" you found sounds like something I've done to the rocker boxes of my old Daytona many times to slow the flow. Much as my old Trumpet must have thought different, the inside benefitted from the lubrication much more than the outside did. I think the gasket surfaces on the Conti are probably truer and more oil tight than the ones from Coventry .

I think the aluminum gear KHODGES and I are doing for his COX arf will lend itself to the correct appearance rather well. Among the many other things I have unfinished is a mod to the PICA based build that will allow aluminum gear to be attached while retaining the stringers and F-6(?) former. I will definitely share the mod with you guys as it is mocked up and hopefully implemented into my project. I fly my stuff a good bit and the permanent nature of the stock PICA set-up makes me a little nervous.

I think the aluminum gear KHODGES and I are doing for his COX arf will lend itself to the correct appearance rather well.

A small detail, to be sure, but one of the things I noticed about the gear on the full-size vs the model is that the rear of the fairing on the model joins the fuse forward of, or just at the lower wing L.E., where the full scale's joins behind it, under the wing root. I hope to make the aluminum gear mimic that a bit closer; easier to describe with pics once the mod is done. I need to get my arse moving and send Jay my drawings. I also worked on a horseshoe-style tailwheel fork, more accurate for the majority of all types of WACO's than the squared one that the Classic/Super used, so it can be used for YMF, UPF, UBF, or even the cabin models.

'Stalker---there's lots of things in rural Tenn that are noisy, fast, and low. Most of 'em are for running moonshine, though.

Ken,

Small details add up to make the whole thing right. Here's a picture of YMF Classic, NC 14081, that shows the detail you are talking about. Also note that the rear edge of the fairing is screwed together.

You keep posting those pics, man, I'm gonna have to come out there, again I could easily become a "hangar gypsy" at CCA, just wandering from one to the other. If you hear of next year's fly-in date, let me know. I gotta get my vacation time reserved.

Man... so much for OPSEC... we intentionally blew the barn down to sling-load out the Master Chief's stil... but it was EMPTY... Negtive contact, OVER... seems all his chickens and milk cows drained it before H-hour... and then there we were... in Clarksville at 4:30 AM drinkin' warm pitchers of beer (no 'shine) and likin' it... not our best night
