Thank you John.
Is the event at Creve Coeur airport the one we have been talking about here, right? I can only go to one.

Angel,

Yes, Ken and I have been talking about the AWC Fly In we attended, but I can't compare it with the NWC event since I haven’t been there. Many of the same planes and pilots go on to the NWC Fly In after the AWC.

Based on my experience at the AWC Fly In and Creve Coeur Airport (I live about 45 miles away and frequently visit), you can expect to see a bunch of Wacos (about 40 were there in 2007) and many other unique aircraft from between WWI and WWII. You will also meet and be able to talk with many pilots and aviation enthusiasts. The Museum (Historic Aircraft Restoration Museum) will be open to all AWC members (about a dozen Wacos and about 50-60 other planes, most in flying condition); many private hangers will also be open with aircraft of all sorts in all stages of restoration from bare airframes to complete restorations. There are also a couple of WWII aircraft based at CCA that may also fly. There will probably be a couple of seminars and demonstrations and as always, good food.

There is a shuttle van between the hotel (Holiday Inn Express) and CCA, a couple of Casino’s nearby and other stuff in the St Louis area like the StL Zoo, Forest Park, Theaters and “The Arch”.

The only thing unknown at this time is the weather; it was hot last year (mid to high 90s) and humid but everyone survived, although a bit sweaty.

Bob,

You didn't interupt, you asked a legit question. A Jungmann is a radial bi-plane, same as the Waco. Probably the reason you didn’t get a response is nobody has any experience with a .61 engine in a Waco. One of the 1/6th Wacos has a ST 75 for power. Most of the 1/5 scale Wacos have at least a 120 Four Stoke engine. Bill likes the OS Twin 160 for power, but is now planning for a gas engine. I looked at Keleo, Slimline and a couple of other companies. You best bet is probably the Slimline Pitts muffler if you are mounting the engine inverted.

krusstygun,

Your YMF is looking good in the bones. The photo from the tail may be an optical illusion, but the floats look like they have a bit of toe-out. I would think a .90 FS would be close. I think the NWC site has a few pictures of YMF/UMF on floats, check for an additional sub fin for stability.

Back (way back) when I built a 1/5 scale Pica Waco, I powered it with a HB 61 engine, It had sufficient power to fly large loops. I now am finishing a 1/5 scale Pica Jungmeister powered with a OS .61 FX engine, and want an in cowl muffler (not loud),I have a Slimline on back order, and was wondering what else was available. I'm sure the Waco & Jungmeister cowls are the same size. Any advise will be considered.

Bob
Bob, You were not being ignored, nor is this an elite forum. I didn't see what you were referencing until just now. I apologize if it seemed as if your post was being ignored.

Best as I can recall, the HB 0.61 was a very long stroke engine, and as such could turn a fairly large prop for it's size. I don't know if the O.S. 0.61 will deliver the same torque as would the H.B.. Having said that, do you know approxomately how much your WACO will weigh? A Biplane that is very, "Dirty", drag wise is going to be an awfully heavy load for any 0.61. With my experience, you will end up with a bunch of dead weight at the firewall just to get the plane to balance, so why not use a larger engine that weighs more to achieve that end. I would rather see you add weight that has some use, rather than a lump of lead.

As to your muffler question, I would think that if the Slimline was on back-order, it would not be for long. You might want to look at the Bisson muffler. I don't know if they offer them for an engine like the OS 61, but there should be any number of manufacturers out there who have similar mufflers for that engine. Are you mounting the engine straight up, inverted, sideways? All these would make a difference. What about the new muffler from OS? It will fit many applications, and is very versatile from what I have seen. You will have to forgive me, but I haven't used an engine in this size class for years (except for a couple that I have had for lots of years, and were powered with Webra's).

I do think that the 0.61 would be better suited to the 1/6th scale version. (for what it's worth)

any one ever think of putting one on floats? i have a dave platt ymf 3 that i have framed up so far .
i was also wondering what engine would you recommed straping onto this 1\5 scale plane
i did some searching and found that they first used edo floats on this bipe
The biggest one that will fit. Seriously, if I were going to put one on floats, I would probably use the G-26, or the OS 160 twin. Both engines will have sufficient torque to spin the prop (Nylon or some other composite) prop hard enough to fly the pig. I think that you will still be full throttle most all the time.

Hi John,

After even more thought, I have decided to go with what I have [ Pica YMF-3/5, 1/6 scale ]. I realize most of this thread is devoted to the 1/5th scale, however I feel sure that many of the issues raised/discussed will also apply. I have a few questions that perhaps you, or one of the other Brothers, can answer.
1. Will the OS 61FX work power-wise? The kit call out a 61. Also, if my eyes don't deceive me, the 61FX will fit inside the cowl with no need to cut holes. [I HATE seeing cylinder heads and mufflers sticking out ]
2. Are there any sources for stock fiberglass parts, like cowls and wheel pants for the 1/6th ?
3. If there is no cockpit kit with instrument panel for the 1/6th, can I get one for the 1/5th and scale it down easily?
4. What covering material and paint would you recommend ?
Thanks for any guidance you are able to offer.

Sounds like a winner! Are you flying down solo, or are you bringing your wife? I'd thought about hanging out at the end of the Oshkosh runway with my thumb out, and get a loooonnnnggg ride
Ken,

As thinks look right now I'll probably be flying down solo again this year. My wife's family has once again managed to plan things on the same weekend as the Waco fly-in. 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 there!

Cheers!

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

Don,

Both sizes are constructed nearly identically. House of Moy (a supplemental site) http://www.houseofmoy.com/waco/ has both size of plans and the manuals if you do not have them.

1. The plans show a .60, so an OS .61FX 2ssould be able to power the 1/6 Waco if built light and extra detail were left off. The new OS 75AX ABL has nearly the same power as the OS .91FX and will swing a larger prop than the .91 (according to OS website) but the 2s would not sound right. A .90 to 120 4s would be much better (and sound better too).

2. Stan’s (Aerofibertech Products) http://www.aerofibertech.com/products.html# lists the Pica Waco Cowl (p/n 913) and wheel pants (p/n 913p).

3. The original instrument panel is easy enough to make (an oval on the former), the newer 3 panel in a little tougher, but still pretty easy. JTEC http://www.jtecrc.com/instruments.htm has individual instrument kits, about $10 for Black and White and about $14 for color in 1/6th and 1/5th scale (and others) or you can make your own housings from appropriate brass tube and make you own instruments in a program as basic as MS Paint. Hobby Lobby http://www.hobby-lobby.com/instruments.htm has instrument sets from PropagTeam http://www.propagteam.cz/home_en.asp in the Czech Republic, but only in 1/5, ÂĽ, and 1/3 scales.

4. You could use one of the plastic films but it won’t look right (horrible really). Coverite would be ok, but my preference is silk (SIG Koverall) and dope. When it is shrunk up tight, it adds a lot of strength to the structure. I have a full size aircraft supply place about 50 miles away and can get Randolph dope and such there and can get the correct colors I need (the LHS has maybe a dozen cans of SIG and Aero Gloss dope/thinner on the shelves).

P1 Detail of instrument panel supplemental sheet, don’t know if it was included in the 1/6th size kit.

P2 Full size Instrument panel from 1932 UBF-2 NC 2091K, almost an exact match to the detail sheet.

P3 Detail sheet instrument listings

Krusstygun,
I'd bet your 1/6 WACO would be sweet on floats. I'd also bet a 60 with a in the cowl muffler would be hard pressed to get her off the water. If it did, not much power to spare tote'n them floats everywhere she goes. If your sticking with two strokes I'd go at least a 90. Most of them should still fit in the cowl.

Krusstygun-- I once has a Sportsman .60 size Waco UPF, had a 58 inch wingspan and was around 1/6-1/7 scale. I had a .80 Saito on it and it flew great, plenty of power for aerobatics. I later put a 1.00 Saito on it which was real overkill, but I imagine the 1/6 you have is bigger, so a 1.00 4-stroke, probably even a .91, would give plenty of oomph, and sound good to boot.

Tony, I had a 6200 Spektrum Rx, which is a 6-channel mini Rx, but full-range 2.4GHz and drove it and the servos with a 1450 mAh NiMH battery at 4.8V. The battery read 5.36V (loaded) just before I took off. The aileron servos were coreless Futaba high torque, don't remember the #, the rudder was a Spektrum high torque digital, and the elevator was an older S-something Futaba, but it had functioned okay in the 5 or 6 flights I got on the plane before trying to take the short route to China[sm=what_smile.gif]. The throttle servo was a Futaba 3001 standard BB servo. I hadn't been in the air more than two times around the pattern when I crashed, still had over 3/4 tank of gas, and previous longer flights with the battery at that state of charge had no problems. C/G was at 25% MAC (I had no info on where Pilot said the c/g was), if anything it was nose heavy because I had to put about 3 clicks of up elevator trim in it to fly level at cruise, which was just over 1/2 throttle. Elevator had plenty of travel, and the same aerobatics had been performed in earlier flights without problem. I'm really at a loss to explain it. If I got glitched or took a radio hit, I'll have lost all confidence in 2.4MHz. My UMF is also on 2.4 and in more than two dozen flights, never had any hint of a problem, and I've never had any problems with 72 Mhz PCM.

I'm totally disgusted right now, don't even want to fly. I tore up my shop this weekend, going to completely clean and reorganize, and start a build. The weather here has been perfect for flying the last two weeks, just light breeze and light jacket-to-tee shirt temps, but I'm going to take a moratorium on flying and do some fixing and building. I might take on two builds at once. I have a Sig Kadet Sr kit that I want to bash into something like a Helio Courier; I've been modifying the plans to add 3/4 span flaps and short barn door ailerons, taildragger conversion, bomb bay and some profile changes. I'll do something like Solartex cover just to shorten the work. The other is my 1/4 scale BirdDog, Vaillancourt plans. I had Precision Cut kits laser cut it and I have the engine already(ZDZ-50NG) Those might keep me going a while........anybody want a deal on 1/2 a Decathlon?

Ken,

Don't get rid of anything. The feeling of disgust will leave pretty soon, and nothing is worse than the feeling that you get right after the new owner backs down the driveway, and you realize that you have sold something that you will never get back. It'll be okay, I hate it that your plane got pranged, but you can rebuild it better than it was before. I wouldn't say that to everyone, but you have the capability. Hang in there kid.
