Hey Bill,
This is such a newbie question I'm embarrassed to ask. It's been so long I just don't remember a lot of things. Maybe it's not the length of time that's the problem but the age of the brain ??? Anyway, when do I epoxy lite and form around the control exits? Before or after covering? I used a solid rod and ordinary old tube. I'll need to shape and pretty it up with a little epoxylite. But I don't remember when....

Thanks,
Sean

Sean,

I quit using Epoxylite after the first time I tried it. I make a plate for the tube to exit through, then I add a little spackle (try to keep it out of the inside of the tube) and then sand everything flush prior to covering. This makes for a very nice exit for the pushrod. The only thing that I put on after the Koverall is the finishing media (dope or paint).

Guys,

I tried to use the wheel pants from Fiberglass Specialists. I found that the width of these pants are way too wide. I sectioned about 1/4" out of the middle of the pants (front to back) and reglassed them back together. Much better. I'll try to get some pics for this operation soon (the computer has been bought, and is at the shop for loading of all the programs). It'll probably take me some time to get used to the new operating system (vista) but I'll more than likely figure it out.

Gentlemen.

I am trying to locate hinges for the baggage door.
on page 43, post 858 there is a picture showing a one piece hinge, and on pg70, post 1395 there is a picture showing 2 separate hinges.
Which one is correct?
I have been only able to find small ones made by Houseworks for miniature houses.

The piano style one piece hinge would be correct (at least on the ones that I have seen) (I could be proven wrong though) There are some neat outlets for miniature hardware on the net. You should be able to find some piano hinge material there. I saw a website for strip hinges the other day that were 6" long. I'll try to find it and post the address here.

Angel,

Bill is correct; a piano style hinge is used on the hatches (P-1). All of the different Wacos I have seen, that have baggage hatches behind the rear cockpit used piano hinges. The baggage hatch size and shape on the various Wacos have been approximately the same (one exception, a Taperwing with a longer, narrower hatch). The biggest difference I have noted is in the lock area, most had a "Platt" style lock (P-4, looks like a briefcase combination lock). The hatch cover was either even with the "tongue”, notched to fit around it or pierced for the tongue to pass through (P-4). The YMF Classic (NC 14081) that attended the Fly In had the notched variety.

Bill – The third picture has another view of the spinner for you to ponder.

John,

I may be completely bass-ackward here, but I still can't shake the memory that my Grandfather's WACO used a spinner that looked like a smaller version of the AT-6 spinner. That was at least 50 years ago, and we all know what years do to the memory....(or forgettory)

The only picture of a YMF-5 with dome spinner that I have seen from yesteryear. The FAA Says this 1935 YMF L4 N14134 c/n 4211 was last actioned in 1977 and is not currently air worthy.

Edited to ask if the cowl was smooth as well. The creator had a "look" in mind for this one possibly.

The list of resourses compiled as to plans on House of Molfoy is a timesaver but the one plan namely the Waco Model D by W.E. Technical Services at $92 is incomplete. It is a nine sheet set but the AMA only has 4 of the sheets. Of the ones missing is all the wing plans, a canopy sheet and I dont know what else, as I have not seen it. I told the AMA but they continue to offer them. They gave me my money back for the plan and let me keep the incomplete set. This part set would help a little my efforts to create my own set. It will likely be too much work.

I had been aware of these plans for some time and did not buy them as a result of Molfoy having sourced them. I just don't want to see anyone else buy them without knowing this. I still had to pay $40 for postage taxes and fees for Canada Customs.

Maybe a disclaimer added to the plan info would save frustration for a prospective buyer of plans. There are no other plans for this quarter scale D Waco. There are FG parts for it though by another name. If I complete a model then the plan would be of value, otherwise a waste of a dream, the money does'nt matter.

'Yellowjacket" One of many variants.

Bill,

We all get a case of CRS now and then (it comes with the territory which we now reside). The spinner shown on NC 14081 (1987 YMF Classic) is only relevent to that particular plane (and one other I have seen a picture of) and was offered as an alterative suggestion to the AT-6 style. The 2-3/4" AT-6 style shown above also looks good as does Ken's "no-spinner" version.

Joe Aveage,

Thanks for the info on the plans on the Waco Model D by W.E. Technical Services. I will update the plans listing and send it to Chris to post on the House of Moy. When I gathered the info to make the list, I could only go by what was published by the various sites, as I don't have the resources to check each and every set of plans for acuracy and completness.

The picture of "Yellow Jacket" you have posted is one of the better I have seen of N 14048. It was suppose to come down to the Fly In in June, but time constraints prevented its appearence. The plane is currently based in Vermont as I recall.

The plane and the place go together.

mrdhud - Dan this refers to your post back on June 21st. I like the looks of your "corrugating" for the ailerons. How did it work out for you and if you used it what adhesive did you use to adhere to the balsa formers? I have some nice light aluminum sheet from the local auto repair store that is .015 thick and I think it will work perfectly using your method. I need to make 24 of them !! so I hope it worked??

My own CRS is going full-bore right now; help me out guys, who is the old fellow I had a picture posted once, who had a 1/4 scale D in Cuban military paint? I wonder if his plans are available?

Clyde McCulloch??? is that him?


Master Chief---glad to hear your 'puter's 'putin' again. It was almost like you'd moved away. 'Course, we'll not get any more rest, now.

Just for that, I won't tell you that it was Claude McCulloch that built the Cuban WACO. But, that was pretty close for an Air Farce Puke.

Claude McCullough did have a set he designed but he gave them away. They were for the Cuban style with the UPF-7 vertical stab.

Joe A, Ken, Bill,

Our Canadian brother is the winner of the “spelling bee” and got Claude’s name spelled correctly. (Geez, you officer types, got to let the enlisted keep you in line ).

Joe, your info pretty much matches what Claude told me earlier this year. I’ll add that Claude said that the plans were pretty rough and his cowl was an aluminum pot. He did send me a copy of his presentation package with three-views.

The Tail group was that of a YOC with the little air balance on the rudder, otherwise very similar to a UPF-7 tail. Reference Waco Drawing #297, dated 10-20-36.

You're right about the YOC tail. My UPF was a long typo. I was surprised when I read it. I picture the D as a bigger plane. It's just different from the others. It will handle a P&W 985 though. I think it is only the E's otherwise that have the big 9 cylinder.

Joe A.

The S3HD-A had a wing span of 32’ 6-7/8” (or 32' 9” depending on source), only about 2-1/2' bigger than the YMF (30’ 0” ws).

A CTO, N 280W, nicknamed “Question Mark” has a 9 cylinder Wright 975 E&F-2&3 engine and set a number of “Time to Altitude” records. Based at CCA near St. Louis and is in flying condition. (p2) SRE in background.

The SRE also has a P & W R-985 Wasp engine and is a good size plane at 34’ 9”. Here is a head on view of the SRE, NC 58785, taken during the Fly In, (“Question Mark” is peeking in on the right). (p1)

Bill, a nice AT-6 style spinner to drool over.
