RE: WACO YMF
Yes pinking tape wing tip to wing tip. If you were to use 2" tape. you would be in the neighborhood of a real airplane. i don't have my model with me but it should be 5/8 to 3/4"
I am not getting into that discussion either

RE: WACO YMF
Well after going threw photo's again, I'm getting all discombobulated. I ran my rib tape up to the solid ( sheeted section ) of the front. Now after review it look's like it was suppose to run all the way to the leading edge. I think?
aminjet, I also ran a tape along that point ( top and bottom ) that is also where I stopped the rib tape. I thought there might be one on the leading edge as well. Was'nt sure. Still not. Now I'm thinking I need to extend the rib tape to the leading edge?????
A tutorial on the subject would be more than welcome.

RE: WACO YMF
Let me re visit the pictures i have and i will take a close up picture of my model when i get home by 5 PM central.
I think I have one or two showing the tape location.
As I remember when i went to A&P school 40 years ago there is supposed to be a min. of 4 inches overlap on the fabric, where you do the overlap I am not sure if it really matters as long as the over lap is with the air stream.
The purpose of the P tape is to help keep the overlap fabric from coming undone

RE: WACO YMF
Not being familiar with the Skybolt's airfoil, I'm not able to make a comment on the upforce necessary by the stab to cancel excess lift (climb) at higher than cruise airspeed. My guees is that it's a semi or even full symmetrical. The Waco's near flat bottom Clark Y airfoil has lift even at slight negative AOA and rigged with a bit of positive incidence the lift goes up loads as speed is increased past cruise. The stab on our models is set at a fixed COMPROMISE for mdium throttle flight. The CG is set to insure good handling qualities throught the speed envelope. We're talking about scale models and civilian light planes for the most part.
The speed envelope demos are done at TopGun (I've been a contestant there most recently with a 1/3d Waco YMF) for 2 years and with a 1/6th B-17 for 6 or 7.Scalemasters and FAI also demonstrate speed envelope. Mitch

Robert,
The rib tapes should run all the way around the L/E. The perimeter tapes go over the rib tapes and run from the wing root all the way around the tip and along the top and bottom of the aileron bay and over the trailing edge. The Waco will eat alot of tape. I used over 300ft on my 1/3 Waco.

In a steady climb the lift is actually less than the weight.

Robert.
I mis understood what you were asking, Waconut ( Anthony ) is correct, went back and took a second look, the size I used over the ribs is 1/2 " and 3/4 for the perimeter tape.
John Howard has a nice picture I am thinking of that shows where it goes, I didn't copy it.
Hopefully John will post it again

RE: WACO YMF
Thank's stickbuilder, that is kinda what I was thinking but really had no idea. Photos don't show the tape much.
aminjet I used the same as well. Thought a 1 inch would be good for the perimeter, but with the difference between full scale and the model
( as pointed out by stickbuilder ) it just was'nt looking right. I've got it now.
And Thank,s to WacoNut for The helpfull info also, now I know I need to extend the rib tape farther forward.
So now I'll go back and extend the rib tape and wrap the perimeter with the 1inch
Thank,s to all for the help, very much appreciated.

RE: WACO YMF
I think that the standard 'pinked' tape is 2" wide and the perimeter tape is 4" wide, bias cut. You can work out scale sizes from the scale of your model.

RE: WACO YMF
All,
I did not see any Waco Brotherhood shirts at the American Waco Club Fly In this past weekend at Creve Coeur Airport near St Louis, although I did see a lot of Waco Shirts of all types. Sorry you guys missed it. The number of Wacos that actually flew in was down this year, mainly due to weather to the north. Some aircraft were down for maintenance (YMF NC 14081 was getting the wings recovered) or repairs (SRE NC 58785 got caught up in a severe cross wind landing and flipped requiring 2 new wing panels and some other stuff, no one hurt). Some new plane did show up;
P1&2 – Waco ATO, NC 5533, also know as the Baby Ruth Waco was recently restored by Olde Tyme Restoration at Creve Coeur. Part of the Museum Collection.
P3 – Waco RNF, NC 144Y, also known as the Roy Timm Special that was flow in the Cole Brothers Air Show from 1952-1960 was also restored by Olde Tyme Restoration at Creve Coeur. Part of the Museum Collection.
P4&5 – Waco CUC-2, NC 14625, owned by Bill French based at Creve Coeur.
P6 – Waco UPF, NC 32032, Grand Champion at Oshkosh as the most authentically restored UPF as used by the CPT program during WW II.
P7&8 - Waco UKC, NC 14052, owned by Kevin Hogan, Hamilton, Ohio, arrived just as dark was settling in at the airport (about 9 pm CST). Note the baffles used between the engine cylinders.

RE: WACO YMF
Lets see if I can help out on the taping. These pictures are of a YKS wing that was being restored (similar in construction to a YMF wing).
P1 – The bare wing showing the aluminum leading edge sheeting and the forward position of the spar compared to the model.
P2 – The wing tip covered and taped. Notice the spar tape covers the rib tapes and the ends of the last 2 ribs. The end of the spar tape is covered by the tip tape.
P3 – The wing tip covered and taped. The rib tapes are over the leading edge tapes and was cut to fit around the light mount. The tip tape was applied last.
P4 – A side by side of the wings. The bare wing need the leading edge sheet metal (sitting on the wing) applied from the spar around to the spar.
P5 – A view of the aileron bay

RE: WACO YMF
Thanks for reposting those photos John. We need to see them each time this question comes up. I still wonder why they designed the wings with the spars so far out of kilter...............

Where are you coming up with all this crap, and exactly what are you attempting to accomplish? If you are simply trying to show off your knowledge (sic) of aerodynamics, you have made your point. Otherwise, W.T.F.?

RE: WACO YMF
Bill,
As for the distance between spars, with the front one so far to the front, I can only speculate that it was to accommodate the fuel tanks. On an open cockpit the main tanks are in the upper center section and to allow the outer panels to connect spar to spar, the spacing was continued to the outer panels. On the cabin models, the main tanks are in the outer panels and connect directly to the fuselage. The pictures are of a YKS wing (cabin model). My guess for the lower wing is since that many of the ribs are the same, it was expedient to use the same jigs to make ribs for the lower wing which would put the spar spacing the same.
P1 - Empty tank bay
P2 - Tank in place.
