The original verticle fin/rudder on the UMF was smaller than what is seen on the YMF-5 today. They were increased to help with a stability problem and most of the earlier U/YMF with the smaller verticle were upgraded either at the factory or by the owner.. Waco had a number of different tail groups. The U/YMF is one and was used on the YKS and others. The UPF has a taller thicker shape on the verticle and the horizontal has a much thicker airfoil and recurves back to the fuselage. Similar verticles were used on the SRE and others. The AVN (and relitives) was different again and was also the only tricycle geared Waco The CSO, CTO, ASO, ATO had very flat surfaces and round verticles and appear to be just stuck on the fuselage like a 25ยข stick glider. There are many variations for Waco Tail Surfaces and when you think that Waco produced over 100 different models of bi-planes, it stands to reason. Take a look at the National Waco Clubs Photo Album to see the variations. Any time you get a chance to see a Waco, go for it. The American Waco Club has its annual Fly in at Creve Coeur Airport near St Louis and the National Waco Club has theirs in Mid Ohio, both Fly Ins are in June and you can expect to see a lot of different Wacos. |

Pepino Waco ARC for sale if anyone's interested. http://www.rcuniverse.com/market/item.cfm?itemId=608931 Looks like it was a strip down and recover job that needs completion. |
RE: WACO YMF
Way back ,I think it was Cubman that used small brass hinges for the ailerons, he said he replaced the wire with.040 wire I believe. This was to make the hinge move easier. My question is how to pull out the wire I've tried many times and it breaks. Did yoou heat it or something?

RE: WACO YMF
ORIGINAL: [email protected] Here are some pictures of how they were set up when i got it. I have tought about making a adjustable stab but still am thinking about it. I've thought about using a set screw to adjust it. I am noth shure how I will keep the setscrew from baking out though. If I were to locktite it I would need to back out the screw each time to re-locktite it. Going the servo route I would need to purchas another servo. How strong of a servo would I need? Would 70oz per sq in be enough? The down side is that Im 16 and am working on a limited budget. Bill, Waco Brother #1 |

RE: WACO YMF
I second that. I've known Jeff for a long time, and he does great work. He's quite prolific, he usually has one or two up for sale and a few in the wings in various stages of build.
I know he flies too, but he's really into building in a big way. He's a really nice guy too. If Jeff built this, it should be some nice work. ~ Jim ~ |
RE: WACO YMF
F.C.
Do you have a way to check the stab incidence? If the stab is correct, my thought would be leave it as is and cover. The reason I went the adjustable route was my stab was off quite a bit. So I had to cut it apart anyway. The adjustable stab is not hard to build but does require a bit of fabrication. You have to replace the stab platform with lite ply to support the rear pivot and once you have that done and the stab works to your satisfaction, you need to a piece of hardwood or I used lite ply and balsa for the vertical stab mount. After I got the verical stab where I wanted it I cut small formers and used 1/16 balsa to form the fillit for the rear of the fuse. The pictures John just posted show very clearly the aluminum fillit used on the restoration project. If you decide to go the adjustable route I can tell you how I made my adjustment so it will not back out |

RE: WACO YMF
Pica produced two sizes; a 60" w.s. and a 72" w.s. Which one did you buy on ebay? I still am flying the larger one I build about 1985. Great flying airplane.

RE: WACO YMF
I set the moter mount at 0 degrees and got +2 degrees of incidence for the stab. I looked at the plans and couldnot find out if the mouter mount had any up/down thrust built in.
|
RE: WACO YMF
Sounds like it is close, to be sure set the crutch to 0 degrees and check the stab incidence. The crutch will be the 1/4 stringer just below the cockpit opening. While the motor mount should not have any right or down thrust (per design) the crutch is what all your incidence measurments are referenced to. Again if it is correct (and it sounds close) then I'd cover it and move forward. Lots of these old airplanes were build without adjustable stabs and they flew just fine. As long as they are balanced correctly i.e. center of balance about 28% MAC

RE: WACO YMF
Hi Neil,
I have call the comp. in question for the garage door covers. They are accepting US funds a standard picture will be 229,- US dollars. Peter |
RE: WACO YMF
Thank You Peter. I am looking forward to communicating with you more in the future as I have decided to build one of your kits (1/4 scale Waco)in the near future, just as soon as I can set the shop up for the larger model. Thank you very much for checking on the motif for me, I will be placing an order soon. Take good care.

I don't know about that engine, but I'm building the new 27% (97.4" span) YMF-5 around the Zenoah GT-80.

Bill,
How do you think the OS FT300 will do in the 27%? |

RE: WACO YMF
Yes, I'm not wild about the traditional wing-bolt hold down on the 1/5 scale. My rationale in looking at a three section wing is that the Pica wing is three sections anyhow , you could then incorporate the lower wing center into the fuselage (as you say), and make the top wing center fixed on the cabanes. Your dihedral would have to be determined by the wing tubes (or whatever) in the center sections. Might make it easier to set up proper incidence and cabane mounts, though

RE: WACO YMF
Anybody interested in an Ikon 1/5 scale UPF-7 kit? Just as I bought it, nothing's been removed, box only opened once. $150, buyer pays shipping. Got several 1/4 scale BUSA kits also. PM me.

RE: WACO YMF
Ken.
I promised my wife I wasn't going to build another one. What's available? |
