WACO YMF
Stans is bigger and deeper. There is a guy at my field with one of those ARFs. I'll keep my cowl in the truck to see if I can compare.
Got the middle framed and covered (top). I split w11b in half and used the ply on the front and back of the front spar.

Rob have you read the revised manual the Brotherhood put together has some good tips.

The cowl from Stan's is done from one of my cowlings. Jay (damifino) built the cowl and sent it to Fibertech and he pulled the mold from it. It is exactly the same cowl that you have only in epoxyglass.

Okay here's an update. Stan's Fibertech is now called Fibertechnmore. They are listing the 1/5th scale YMF cowl for $57.95. It's our cowl. Looks like they finally found the mold.

At the last auction I attended I got, among other things, A WACO cowling for the 1/6th and wheel pants which also seem to be WACO-like and are larger, so I assume for the 1/5th. The part numbers written on them match I forget which company's fiberglass catalog. I do not need the wheel pants and anything will be a net gain for me. The part number is 70. About 9 1/4" long by 2 3/4"-ish wide. Wheel opening is 4 7/8" x 2 1/4".
Denny, when just get home I'll measure the ones on the plans. Thanks
Bill, see how that cowl has a wider opening. That gp cowl looks like the cowl on the radial rocket.
On a side note, of you do not have forstner bits, a 9mm casing with the edges sharpened will make a nice servo lead hole without fraying the wood. Also fit right into the chuck of the drill.

I hope it is not bad form to reply to one's own message. Since nobody said anything about the wheel pants, I will just state for the record that they appear to be Fiberglass Specialties #70 wheel pants and are 9 1/4" x 3 5/8" x 2 5/8" for 4 - 4 1/2 wheels. $10 plus the sipping. [email protected]
Thosr are for the 1/5 th scale version.

That is the cowl that was taken from my cowling that Jay put together and sent to Stan's about 10 years ago. It's our cowling. Order it and your cowl problem is over. You still have a hill to climb with the wheel pants. They are all too wide (side to side) you need to section 1/4 inch out and glass them back together.

Shear webbing on the spars.
Pica cut the webbing blanks to roughly the gaps between the ribs. The orientation though of the grain runs the same direction as the shear forces (horizontal). I would thing the grain should run perpendicular to the spar. Am I missing something...does it really matter?
Update for last night, Kansas tornado warning and hail limited build time. Had to rescue car and so forth. Got the ribs installed on the right bottom wing to the wing tip. Pretty straight forward to this point. I thought a bit more on that big empty space where the wing servo usedan to go. Candy bomb drop bay? That ought to make the scale guys go batty.... kidding Bill.
Will a covering like Koverall adhere to fiberglass. I was considering using a thin layer of glass on the sheeting joints and where the wing screws will go in. Generally I put a small piece of ply there to keep the balsa from being crushed. I though some glass might fair into the profile better.

I am looking for a little help from the Brotherhood with respect to doing another build. After successfully completing my Pica 1/6 th WACO (with a lot of help from this thread) I am now trying to find another plane to build that has similar lines to the WACO, from the Golden Age of Aviation, but only a low, single wing version. I guess I just fell in love with those graceful lines!
I am am currently looking at the Hostetler Red Lion as one that comes about the closest, as well as the Miss Los Angeles, B2 racer as something similar. My ideal plane would be one that uses the WACO cowl, fuselage, tail feathers, and a low single wing. Is there something like that in a 1/5 size? Is it possible to modify a WACo accordingly?
i hope that you won't consider this a major diversion from the intent of this thread, and I apologize if it is, but just thought you guys with a lot of experience, might be able to point me in the right direction.
thanks

I would recommend the travelair mystery ship. There are plans and there were kits out there in 1/4 and 1/5 scale. It is my all time favorite next to the hughes h1.

You have me in Thompson trophy mode now. Type that name into youtube and see a full scale!

Thanks dirtdart, that mystery ship sure does come close, and is a cool looking plane !
If there is a better thread to refer this discussion than here, please let me know as I do not want to detract from this thread. Thanks.

For servo installation, I decided to go with easy, instead of scale. I am mounting the servos (JR digital on 6v) inverted, the mounts will sit flush with the wing fabric. The top 1/3 of the servo will hang out. The choice comes from ease of inspection and maintenance.
dirt, I have found that it is just as easy to mount the servo to the servo cover and then screw this to the wing .
