Hello All
I received e-mail from Brad that my cowl is just about ready to ship out to me. I still need wheel pant. Has any one ordered them from Brad or any advice where to buy them will be appreciated.
Thanks

I have used the ones from Stan's, and also the ones from Fiberglass Specialists. They are all too wide, and need 1/4" sectioned out of the center. It's easy to do, and makes a better looking plane.

You tell me what "the appointed hour" is and which end of the runway, and I'll be there. As far as taking anything with me goes, a change of skivvies and a camera are all I need. Heck, I'd go naked for a ride like that

So if you wanna fly down with me you'll need to show up in OSH at the appointed hour.
Better ship your stuff to Creve Coeur though. There ain't any extra room for bags and baggage in the Waco once I get my stuff in

What is the preferred method of attaching the F/G cowls to the fuse? I would use aluminum "L" brackets and with other aircraft I have F/G'd the "L" bracket to the cowl and used long hex drivers to access the screws to attach it to the fuse. This has not always been successful nor easy to accomplish. Other than that I could run screws through the cowl and into the already attached "L" brackets, but then unsightly screw heads would show on my soon-to-be pristine cowl! I'd appreciate any suggestions. Stickbuilder, how did you attach that gorgeous cowl you have labored on for so long? No screw heads showing on that I'll bet

Tony,
Thanks for that info. For guys like me that have been out for a while and now returning to the hobby, it helps to get a heads up on things like that. I had no idea those receivers would "Reboot".
Now I have a question, is there an easy way to put two batery packs. One for the reciever and one for the servos? I have been watching adds and reading trying to figure out what I will purchase for a new radio.

RE: WACO YMF
Thanks Bill - that makes it easy for me! I'm also using the Zenoah. I had F/G'd these brackets to the inside of the cowl on my 1/4 scale Skybolt and it worked for a while. It was installed with a long shaft allen wrench (as Skinny Bob suggested), but the odd wack on the cowl eventually loosened them up. I re-epoxied them in a few times over the years, but finally a radio failure wrote fini to the Skybolt thus solving the problem!
When I get my cowl from our friend Brad, (shortly) I will take another look at it. I fear that using the plywood ring ala Great Planes would compromise some of my cooling. But I built the GP Super Stearman for a friend and it works well for him - and he also used a Zenoah 26. Thanks for the help

RE: WACO YMF
Bill - Further to the adjustable cabanes - it appears that only the rear cabane is adjustable - is that correct? I presume the adjustments will be so slight - if set up reasonably close to the correct incidence - that the front cabane strut joints will be able to take the slight movement created by adjusting the rear ones? (I think that's clear?)

With the G-26 I would only have been able to attach the cowl for about 270 degrees of the cowl diameter, and that was not an acceptable amount of support for me.

Just got back from our monthly club meeting. We had one of the better turnouts in a long time, about 30 or so of our 68 members. We've got a neighbor (she has only lived near the field about two years) who is circulating a petition trying to get our field closed. Claims we fly over her house all the time; there might be a rare instance, and those should not happen, as she is over 100 yards from the end of our runway, and is in a "No-Fly" zone which is clearly noted by posted signs. We can't use that part of the runway due to trees there, and normally the closest we ever get to her house is about 200 yards. We've been working to stay further away, as she has been complaining over a year, on and off, but she is the ONLY neighbor that complains, out of about twenty who have lived there over 30 years (our club has flown there since 1968). Given what it takes to lose a flying site these days, we're worried, but our other neighbors have supported us for a long time and we hope that they will stand by us.
I got voted Prez. of the club. Please, no applause, it was sort of a shotgun wedding. Nobody else wanted it.

You may add your name to those of distinction as well. You have been a positive motivator in this thread as well. We have close to 100 members of the Brotherhood now, and as far as I'm concerned, there is not a stinker in the bunch.

I would be cautious about allowing the front cabane mount to be in a torsional stress situation. I suppose that it would depend upon the material that you had chosen to manufacture the hardware from. I'm not going to use any unobtanium in making my hardware, and I won't leave my cabanes in a bound up situation. It's going to allow everything to be straight, and true (for a change) Remember, the cabanes will work in concert with the interplanes on mine, so I will be able to fine tune the incidence along the entire wing/s.

RE: WACO YMF
Bill, SCM and the rest,
Realizing that our models are experimental aircraft and the need for adjustability may be required to fine tune the flight characteristics, here are a few shots of the full size Waco cabane and interplane struts.
P1 1987 YMF Classic NC 14081, Cabane struts, note the fixed mounting points and welded joints. Also note the plumbing for the fuel tanks
P2 1987 YMF Classic NC 14081, Interplane struts. The center strut is fixed in length, the forward strut is adjustable at the bottom and the rear strut is adjustable at the top. Joints are flexible. See TRLambsrs photos posted by Bill in post 4787, page 192, very similar (bolt and nut replaces clevis pin on full size)
P3 1942 UPF-7, NC 39748, Joe (Waco Joe, pilot) and Ken (khodges) get ready to fly. Note the additional horizontal strut between the front and rear cabane struts at the fuselage. Interplane struts are similar to the YMF.
P4 1940 QCF, NC 12428, is being rigged. Center interplane strut has been installed. Cabane wires and one main wire installed with lots more to do. Note cover removed at the base of the forward cabane struts for rigging and adjustment and the fuselage has been leveled for rigging.

RE: WACO YMF
Thanks for that John - great details. But you know the more I play with these @^&#$@&$ cabanes, and trying to get them set to the right length and cutting and soldering the 5/32 steel wire, (remember I'm scratch building!) the more I think it would be easier to cut off the installed cabane wires and replace them with bolt-on cabanes as on the GP Stearman. The advantage is that with the bottom wing installed, you could jig up the top wing into exact position and incidence and then cut the cabanes to fit. Hardwood run throught the fuse from side to side would act as anchor points for the fuse/cabane screws, or blind nuts in reinforced plywood inside the fuse would also serve. The cabanes together with the interplane struts would hold the top wing in position quite well. This is the scale installation and works quite well with the GP model. It's something to think about! The jig could consist of two supports of an "N Strut" configuration with the top and bottom shaped to fit the top and bottom airfoil of the wing. One would be positioned and tacked to each side of the fuse and sitting on the bottom wing it would hold the top wing in firm position while cabanes and struts were cut and fitted. The jig would be made right off the plans assuring correct incidence and position relative to the bottom wing. If on top of that an adjusting screw was added to the rear cabane strut and interplane strut, all kinds of versatility would be possible along with easy removal of the cabanes for other work.
Just thinking out loud!! Any thots!!

Here is a thought on a way to mount the fiberglass cowl. Not necessarily the easiest way to do this. But it should work out to be quite solid and reasonable easy to use. Not to mention it will work as a baffle to force air across the cylinder/head fins. The sketch is somewhat to scale but I have no idea what the dimensions of your engine are.
My sketch represents an approximate shape for thin plywood. There are four circles located around the center 90° from each other and skewed 45°. These four circles represent standoffs coming from the firewall.
One could fiberglass this ring into the cowl as you have done with the “L” brackets in the past. Locating it somewhere just in front of the center line of the G26's cylinder. Using standoffs, mount this ring/plate to hold proper distance from the firewall based on the plates exact location within the cowl.
There are quite a few options for which way to go with hardware. Just an idea and quick sketch.

RE: WACO YMF
Thanks Rick - I like that idea - especially, as you suggest, it will act as a baffle to cool the motor. This pix shows my front end and I can adapt brackets for whatever I need to position the ply and cowl properly. I get my cowl next week as Brad has advised that it is shipped!! So I can better see how things fit. I like the idea of no bolts through the cowl. The second pix shows my homemade cowl on my late Skybolt. No bolts there either! No plane either[]

Rick,
I have the hole covered up, the balsa on the gear fairings and as soon as I get things sanded smooth will be ready to put some fiberglass on the repaired area. Been waiting to get the glass on to post some pictures, maybe this weekend. Snow and freezing weather are in the forcast so there will be no outside activities on my schedule.
