Yes the prop was turning they other way I realized it when I up loaded it (felt dumb) then it stoped spinning???? don't know how. I remade it hope its right now.

John,

Thanks for posting the list of Plans, Kits and Documentation I have started printed out the templates to get a head start be for the plans get here.

I hate you lot, I spent some time going back and forth in the thread looking for the error, it was not to be found. Then I read it was as obvious as prop rotation AND I MISSED IT. I hate you!

RE: Differences in Pica 1/5 Kits
It is probably impossible to know the exact evolution of the 1/5 kit without buying a dozen different kits from the early Dave Platt kits to the present, but the box & label are not good indicators of production generations.
I believe I read a thread elsewhere on rcu that Bill had a dozen kits in hand.
I built what I thought was a newer kit last year that had the white plane illustrated on the label. I thought it was a late model kit but I then started seeing kits with abs wing fairings on Ebay in other white plane kits. Mine did not have these items so I suspected there was a newer generation.
I went on the hunt for another kit hoping to get a laser cut one. I grabbed a buy it now kit for $280 on Ebay a few weeks back that had the abs wing fairings. I was thinking that this would also be a laser kit, but ended up with another die cut kit. However, the differences in my first white plane kit and this one are more than just minor. I can only guess that Pica was trying to improve it as production continued.
This kit has a much stronger ABS cowl and the abs parts are much better all round, thicker and with no heat distortion. The die cutting is excellent (really) and all the ply parts have the id numbers nicely stamped on all of them. It also comes with additional ABS wing root fairings and landing gear fairings along with a vacuum formed windscreen of which my earlier white plane kit did not have these items. There is also an update sheet of instructions to clarify and modify certain construction processes. Aileron horns are still positioned wrong though on the main plan sheet.
The quality and cut of all the wood is better. However, all the wing ribs are die cut in ply instead of balsa. Why that change was made is a mystery to me. And they were not just using ply because they ran out of balsa. The die layout is different than on my kit with the balsa ribs. All the ribs now fit on just two long ply sheets. The wood for the wheel pants is also pre carved and shaped blocks instead of just thick balsa block sheets. That was a nice touch.
The inventory wrappers around the wood packs are also typed with clearer and better fonts. Anyway, I will still be on the hunt for a laser cut kit. By the way, what brother did I buy that Howard DGA from, who is wfortney? That Howard is a sweet kit.
This is just an FYI on white plane kits.

Ron,

I think that you are on a wild goose chase for a laser cut fifth scale kit. According to everything that I can find, it appears that only the later sixth scale kits were laser cut, and that none of the fifth scale models were. Every kit that I have are of the blue plane, and none have the extra plastic fairings. The one that I am currently building was one that I recut from an early kit. The die cutting left tons to be desired, and the wood was not very good.

I think that Pica was trying to solve the weak wing problem by going to the ply ribs, when they could have eliminated the problem by redesigning the wing joiner system. The joiners need to be made longer in order to provide more shear strength, and then the balsa structure will stand the rigors of flying.

Just my opinion, but one that bears looking into.

Glad to see you back in here.

Ya, they may have beem trying to solve the weak wing problem, but it would be strange (real strange) to change the rib strength to solve a center folding problem. It probably does not add much weight overall, but I do not think ply ribs is the way to go. The 109" Sirius plans I have from Wendell have balsa ribs, I figure he knows what he is doing. I do not know at what point or size you would replace balsa ribs with ply. I would think all the forces are on the spar, T.E.'s and L.E's and center root section.
I am using this kit for research, I will eventually sell it when I find a laser cut. If I did build it, and I am not, I would redo the ribs in balsa. Anyway, I saw a 1/5 laser kit go for 420 bucks last fall on ebay. No doubt it was a laser cut, it had a huge banner sticker across the box top stating so. I was in the middle of my build so I was not interested at the time, not for 420 bucks anyway. It is out there to be had. No wild goose here, i done seen it with mine own eyes.

Stickbuilder

As I said, I've been wrong before, but that is the first one that I have heard about. I'm with you....If I were to build it, I would recut the ribs from balsa and do the mod on the wing joiners.

John,

This UKC type is what I have in mind. The aftermarket parts for the Pica would fit interchangeably.

The YMF/UMF influence is undeniable. I have seen the various alternative scale plans and ARFs for other models.

With the available parts and the flavor of the model I think you know where I am coming from on this one.

Van,

It does appear that the YMF/UMF share parts with the YKC/UKC. Just looking at photos, the wings are similar outboard of the root area, landing gear is similar in the center strut pivot area and attachment of the center struts to the main struts are above the Oleo section (the YKS center struts attach lower, nearer to the axels), the same cowls could be used (same engines) and the vertical fin/rudder are similar. Make a new fuselage, figure out the upper wing root areas, stick the rest on and you should has a YKC/UKC. The YKC/UKC has a longer fuselage at 25'4" vs 23'4" and longer wingspan at 33'3" than the YMF/UMF at 30', but that could be explained by mounting the wing panels to the cabin with different root areas instead of being joined to the center section with straight root areas. You would need to check the chord length to be sure although the construction should be nearly identical. (If a YMF/UMF shows up at the Fly In, I'll check the chords).

NC 14073 (Red YKC) I found on the internet, NC 3NX (White YKC) is in the Museum at CCA, note the larger smooth cowl on NC 3NX and no triangular rear windows. Also look at the lower wing of NC 14073, it has 2 (one each side) "canister" landing lights and NC 3NX has the flat light in the upper wing. There are other differences that are not as apparent.

Sorry about the time you spent looking for the problem (thanks for trying) hope you were kidding about the hate part.

Vandolay

John

NC 14073 is also the little photo in my post. So you do understand. All that you say is true and I have considered most of it. I'm sure that with the info and Platt plan I have that I can hash out a good stand off YKC. I appreciate your interest.

Platt/Pica kit "stand off" standards are really quite accurate. I'll be happy if I can parallel that. No small task but entirely do-able. Should be fun.

Have you checked the Pima ZKS-6 project? Some new pics there.

PS: love the aditonal photos you add of the other subjects. It helps lay the groundwork for a well rounded Waco experience aside from it's direct relevance.

Ron,

You are correct about laser cut 1/5th Pica kits. I've seen a couple on eBay and one did go for about $420.

Here's a picture of the kit that was on eBay that went for that $420. I have more pictures of it somewhere but without belaboring the point I'm sure this will suffice in serving to demonstate that your memory is working fine.

Do you have link or location of the Pima ZKS-6 project?

For the ZKS-6 this link shows fresh photos and will load for anyone

http://www.pimaair.org/Acftdatapics/WACO%20ZKS-6.htm

and if you click on the "Click here to check restoration status" link further down the page it will load everything else they are doing as well as it takes you to four earlier photos, fair warning for low speed web users, 200 plus pages.

Van, Ken,

The second picture of NC 13446 is very close to Kens paint scheme of NC 14132 used on his Cox/Pica YMF. The tail numbers are the same as the first picture of NC 14132 Van posted. Ken you could have gone with a smooth cowl and simpler paint scheme. The vertical tail is slightly different also.

My Feedback: (1)

I sure would like to see a color picture of NC14132, be nice to see what the original colors were. The one with the smooth cowl and no wheel pants looks like a base model YMF, sort of like the old Biscayne Chevy, compared to the Impala SS. Simple sure would have been easier to mask, but it's done now, ain't no goin' back. That scalloped scheme has some variations, doesn't it. The one I patterned mine after is scalloped top and bottom on the wings and tail; I only did the tops.

I notice the difference in the tail. It has a balanced rudder that is different from the new Super's.

What would you think would be a reasonable cost for a laser cut wood kit of this particular model? The reason I ask is because I am in the process of starting a laser cutting business of my own. Due to the rather large financial investment, it will probably towards the end of the year before I am up and running. I would love to provide a whole series of Wacos, and of course provide a discount for the Brotherhood. Any suggestions on which models you would like to see?

NC 14132 in another time. Article form 1989 mag. I think they refer to one of the aircraft that helped identify that underwater airship wreckage discovered recently.
