[quote]ORIGINAL: skylarkmk1 I was just repeating what I was told by a ''pilot'' a few years ago at an airport. [/quote] Yep, happens a lot. And that pilot was no doubt repeating what he was told by another pilot. Having lived with the curse of being both a pilot and a mechanic for many years, I have found a lot of pilots who really don't understand what's going on with their airplanes mechanically. Same thing with many car owners. No worries! I just like to set the record straight whenever I can. Cheers! Joe WB #54

RE: WACO YMF
[quote]ORIGINAL: skylarkmk1 As the oil also collects in the lower cylinders, you will see the pilot turning the prop by hand for a few revolutions to re-distribute the oil throughout the engine and prevent hydraulic lock. [/quote] John and all, The pilot is not attempting to "re-distribute" the oil when turning the prop by hand before starting the radial engine. There is no way to "re-distribute" oil that has collected in the lower cylinders of the engine. Turning the prop is done just to make sure that the amount of oil that's collected in the engine is not enough to cause a "hydraulic lock", which is when there is so much oil in the cylinder that the combustion chamber is completely full. Since oil is not compressible "hydraulic lock" will cause mechanical damage to the engine, usually in the form of a bent link rod. This damage will result in catastrophic engine failure at some point in the future. Not a good thing. So, when the pilot pulls the engine through he/she will instantly know if there is hydraulic lock when the engine stops against a "hard" stop, that being the oil that is not compressible in the cylinder. You cannot "fix" hydraulic lock by turning the prop. You can only detect it. The only remedy for hydraulic lock is to pull the lower spark plugs and drain the oil out. Cheers! Joe WB #54

[quote]ORIGINAL: WacoNut Thanks Joe, This is going to be a fun project and I really can't wait to started cutting wood. I will be making the trip to Oshkosh this summer and hopefully I will get to run into you. I am hoping to ceck out a few Hatz bi-planes while I am there and if I am lucky get a ride. Would like to get a flight in one to keep me motivated. [/quote] Anthony, If/when you get to Oshkosh by all means look me up. If it's during the EAA convention I'll be at or near the Homebuilders' Hangar near the forums/workshops area. Just stop in there and I'll either be there or they'll know where I am. If you are in OSH any other time of year just stop by EAA headquarters (in the museum) and ask for me. They'll find me and we can chat. John Hatz was a personal friend of mine and he taught my wife how to fly. I can tell you all kinds of things about the Hatz biplane. I've flown the original and helped a friend build a plans-built CB-1. I can also hook you up with Hatz owners in the area if you need a ride. Cheers! Joe WB #54

[quote]ORIGINAL: skylarkmk1 Cabane struts are different. The UPF has a horizontal strut just above the fuselage connecting the lower ends of the front and rear cabane struts. [/quote] John covered the basic differences between the UMF/YMF and the UPF pretty well. My only comment is on the statement above. The UPFs did not originally have the extra brace at the base of the cabane strut, and later serial numbers do not require it.

RE: WACO YMF
I'm always ready to talk about the UPF, and Wacos in general. Let me know if you have any questions about the full-size versions. [quote]ORIGINAL: skylarkmk1 Cowls – The majority of Y/UMFs have Bump Cowls (some have been re-fitted with Smooth cowls). The UPFs can have all three styles, Bump, Ring and Smooth. [/quote] Actually only the original UPF-7 and YPT-14 prototypes had cowlings from the factory. All full, smooth cowls. All the production UPF-7s had no cowl of any style and no wheel pants. They were built for the Civilian Pilot Training Program (CPTP, often shortened to CPT) and were painted in a style similar to the Army trainers (blue fuselage and yellow wings). But the UPFs were all civilian airplanes rather than military. The original UPF-7 prototype and the YPT-14s sent to the military for evaluation had the narrow gear like the YMF-5s have. The Wider gear was suggested by the military, as was the larger center section cutout. But the Stearman ended up getting the military contract so the UPFs were built for the CPTP market. My airplane was at Texas A&M during its CPTP days. Let me know if you need any more info. Cheers! Joe WB #54

RE: WACO YMF
[quote]ORIGINAL: tmac48 Hi to all. Can someone help me with a question about the width of the rib stitching and pinking tape on a 1/3 scale Waco. I would like to order the right materials but not sure of the size and where to get it from. Can any one share some info with me. [/quote] Just to try to correct the terminology, the tapes used to cover the rib stitching and other areas that need reinforcing on the fabric of a fabric covered aircraft is called "finishing tapes". The term "pinked" refers to the pinked edges of the tapes (there are also finishing tapes with non-pinked, straight edges). The term "pinking" is incorrect. Typically, the finishing tapes used to go over the ribs after rib lacing (usually referred to as "stitching") is done is a 2 inch wide tape. So on a 1/3 scale Waco the finishing tape over the ribs would be about .66 inches in width. These tapes are almost always pinked edge tapes, as the pinked edge leaves a better finish and helps prevent the tape from pulling loose and curling up over time. Hope this helps! Joe WB #54

RE: [Awaiting Approval]
[quote]ORIGINAL: aminiet The question is, did they use the pinked edges in the 1930's. I am trying to build this bird as close to the original as possible. [/quote] Angel, Yes, they definitely used pinked-edge tapes on the original airplanes. The pinked edges keep the tapes from fraying before and while applying them. The pinking also gives the dope better purchase on the tapes so they don't come loose and curl up over time. Straight-edge tapes tend to "lift and separate" at the edges. Cheers! Joe Waco Brother #54

RE: WACO YMF
[quote]I don't think Dupont Imron is an approved paint for fabric covered aircraft (maybe Waco Joe can help us out). [/quote] You are correct John, Imron is not an approved coating for aircraft fabric. Good thing too, because it doesn't work very well on fabric. (There have been many experimental aircraft that used Imron, and the results are not as good as approved coatings.) I'm not sure what fabric system Waco Classic uses, but according to their website they use "nitrate/butyrate dope finish with polyurethane paint". That would lead me to believe they use Randolph products. There are polyurethane finish coatings for all the approved fabric covering systems. PolyFiber has "Aerothane", Randolph coatings has "Ranthane", and there are other systems like SuperFlight and Air-Tech which use polyurethanes throughout. All of these finishes will result in a very durable, very glossy finish that will last much longer on the fabric than Imron. My UPF-7 has Randolph products on the fabric, and the finish is Ranthane. John can vouch for its glossy good looks!! :) Cheers! Joe Waco Brother #54

But it won't be until next week, as we're right in the middle of board meetings right now so I won't have time to go look at the airplane. The ARE and the SRE are identical airframes. The only difference is the engine - the SRE having the Pratt and Whitney and the ARE having a Jacobs. However, this particular ARE has custom windows that are different from the standard ARE/SRE, as the airplane was built for the New York Daily News and was fitted out for photography. See the following page for info on this aircraft; http://www.airventuremuseum.org/collection/aircraft/Waco%20ARE.asp Note in the pictures the larger than normal side windows in the airplane.
