Ron - I gotta ask... what's YOUR problem???... not that I care... but I am curious (and I do care to some degree).

I flew outta bounds... maybe... slightly (with my reply to Vandolay... yesterday... or Saturday regarding his post) and you jump in with a post (which I read before you editied / deleted your reply #2500)... which had nothing to do with WACOS, so what gives?
I may not always be on topic, usually never, but come on!!! The majority of us like this thread on topic or off.

PM me if you want and we can discuss this off line. I used to like your posts several weeks ago. You seem to be a talented builder, albeit sensitive. I'll give you my phone number and we can talk if you want.

Thanks
Todd

The reason I edited out my post is on hindsite I realized it was inappropriate.
It was only up for a few minutes. Have you ever said something you wanted to take back?
I apologize for letting my emotions get the best of me.
Discretion is the better part of valor.

Anyway, this is how a faired my wing into the fuse on the bottom. The pica kit did not really have any method for doing this. I also added an extra dowel in front. The one per plan may be enough, I dunno, Its not something I wanted to find out during a loop. I built lots of sixty size ships with two dowels, I was a little nervous when I saw that this bigger airplane had only one.
Also, I now wish I had added ply blocks in the wing on the T.E. for the wing screw hold down areas. The balsa is too soft, the big heads of the plastic screws have already made deep impressions in the soft balsa after taking the wing on and off a bunch of times.

Hi, I tried to send you an e-mail last night. Your spam blocker won't let me get to you. It says it can't find the original message so I am blocked out.
Anyhow I would like to order 2 XXl "t" shirts. I can pay via PayPal. I just need to know who to send the funds to. Also Are there any hats to go along with this shirt? if so how much?
Let me know the cost including shipping to zip 91978

Thanks

Off any subject, but still Waco..., anyone have a spare $135K kicking around. I need a 0% intrerest loan, over 60 years..

I am drooling over this thing, not sure why I keep watching it, but I do

BTW, I say $135K, as this will give me about 7K to get a licese... [sm=shades_smile.gif]

Hi guys and Gals. Here are a couple of photos of my Barth Waco YMF5. I'm looking forward to this "Brotherhood" "Miss Linney" is without a doubt my favorite plane to fly.

To All:

I'm going to say this once again. This is a Brotherhood. We discuss things other than WACO aircraft here. If the thread srtictly stuck with only the details about building the YMF/UMF, it would be very dry reading, and friendships would not be allowed to grow. If you have a problem with this, why not start your own thread? This historicially has been a very problem-free thread, and I don't want to see it grow problems. We do not always agree with each other, but let's not let it grow into a urinating contest. Keep it civil, and the Moderators won't be in here with both guns blazing. If necessary, I will begin to do what I never wanted to do...Impose rules for membership. Look in the mirror and breathe deeply 5 times before you post something that is guarenteed to start a fight. This is all I will say on this subject.

Ron - Sorry I high sided as well... that hindsight thing gets me now and again too.

Your wing looks great, by the way. You should consider becoming an Engineer ... (I'm one too.. and that's what really scares me when I build models [X(])

Ron - regarding the problem with your screw heads digging into the balsa, try drilling out the existing thru holes to the dia of your screwheads and then epoxy in hard wood dowels of the appropriate thickness, drill your screw clearance holes thru the dowels and it should beef it up and won't show indentations. You could model it in Solidworks first if you want . If the dowels should ever fail, you've probably got bigger issues at hand. Just a thought.

That is a good idea that will work even now that it is already covered with film. I had toyed with the idea of major surgery installing ply squares in place of the sheeting, but that dowel idea is a very simple fix.
thanks.

Hey All. Can someone show me a simple line drawing of a Waco YMF wingtip? I just want to make sure I get it right. A front view will do, thanks.

Hey no sweat Ron, glad to help out. Can't remember where I saw this or read about it, but I didn't think it up originally. Should work and will be quick and easy compared to surgery.

And who says that Damn Nightstalker never posts on topic I might get used to this on topic stuff... but don't hold me to it... I'm an incureable wise *****

If there's any "ownership" to this thread, it should belong to Stickbuilder, he started it and has long been its prime mover and shaker. That plus the kind of person he is should give him the right to say whatever the hell he wants here. I've watched and read and listened to all this ankle nipping and haven't said anything til now. If you don't like what you see here, go somewhere else. The rest of us will all be better for it.

Bill. Your words of wisdom was followed by me a few day's ago. I'm glad I took a deep breath and relaxed. LIfe must be very good for all of us to be able to spend time on this thread and play with our model aircraft.

Thanks for leading and keeping us on the right track.

Vasek,

No one owns this thread (except RCU). However, someone must keep the peace. I am simply stating that this is a free wheeling thread, but the antics of the last few days will tear the whole thing apart. If I must, I will (as the originator of the thread) ask for the thread to be closed. This thread is too much fun to have ruined. Hope you see things the same way. Please go and look in the mirror, take 5 deep breaths and see if you feel the same way. I will do whatever you wish, regarding your membership.

Dan, the tailwheel is all my design, except the wheel and hub which is a Klett tailwheel. I scratchbuilt the legs from brass tubing and piano wire, based on measurements I made of closeups rom the 'net. I had originally had it fitting into the mount included with the ARF, but it had no shock absorption; it came apart on me the other day at a spot I had feared was weak. I also had no isolation between it and the servo to prevent shock damage to the servo, which also drives the rudder; the Master Chief had some good suggestions as well as Jay, or John, can't remember who posted it, about using nose gear nylon mounts. After I got to playing with things, I mocked up something similar to what you saw, it seemed to work, so I made the one you see in the most recent posts.

The spring linkage at the servo works really well to isolate shock loads transmitted from the tailwheel via the control rod. The spring loading on the tailwheel is a compromise, though. It will give under vertical loads (to the tailwheel shaft), but real-life loads have a vector more at 45-60 degrees to the shaft because the plane is moving forward. The full-scale tailwheel is sprung so that it gives rearward and pivots about a horizontal axis. Mine is susceptible to shear loads that the full scale avoids. Here is a picture of the scale assembly for either the Genesis or Barth (can't remember which), which is the same basic design as the full scale. I am happy to post pics of how I made the forks for mine, if you like.

When I pulled up the pic, my caption says "Palmer tailwheel"

On a lighter note:
two polish guys from Brooklyn hired a piolet to fly them to Canada to hunt moose. They bagged six. As they were loading the plane for the trip home, the piolet told them they could only take three moose. The two guys objected strongly, stating " last year we shot six moose and the piolet let us take all six on the airplane, and it was the same type of plane as yours".
Reluctantly, the piolet agreed and all six moose were loaded on the plane. Unfortunatly, even at full power, the plane couldn't handle the load and crashed shortly after take-off. Climbing out of the wreck, one of the brothers asked where they were at. " I think we are close to where we crashed last year" his brother told him.

Surely someone will have something more "formal" than this, such as a plans drawing or some such, but do these help? Remember, this is an ARF wing, so the structure may not look like yours. The tip design is mine, done from photo blowups and careful proportional measurements. I reused the lit-ply "D" shaped ring on the wingtip, but re-angled it and relocated it on the end rib. The braces out to the tip are 1/16 in carbon fiber strips with a balsa wedge to brace them. Everything is slightly recessed except the last rib, so nothing but the rib shows when covered. I feel like they are as close to the prototype's tips as any model's.

Thanks Ken!! That clears up alot for me. Unfortunatly, it means reconstruction time. I don't know what mine turned out looking like, but they ain't right!! I'll have to saw off the two outermost ribs but think it"ll be a quick correction.

mango,

I don't have any YMF photos yet, but these are a YKS wing tips (both wings from the same plane). Not the exact view you are looking for. If you look close the wings are constructed a little different from each other, but the end result is the same. I'll be back up to CCA on 2 June and can get the head on views you need (of the YKS, UPF-7, UBA or others). NC 155Y, Texaco 17, a UBF-2, shows the wing tip curving up towards the high point from the last full rib (lower wing). NC 173E (Blue UPF-7), the upper wing shows the upward taper (sorry about the glare). The UMF/YMF were the forerunners to the UPF-7.

Here is what I have The taper starts further in on the wing as I see it

Yea, it looks like it starts on about the third rib in. Luckily I only boobooed the last two..........I think. Thanks for all the help guys.

Okay guys. More pictures as promised.

Having the Master Airscrew Balsa Stripper attached to the table lets you feed the balsa through it much like using a table saw. Much easier than trying to hold the wood and the stripper at the same time.
