  Kevin, I built a Drobek for the first round of comps and had 2 goes at the fuse to try and keep it light. I'm not a competition builder and mine was just over the 100 grms but it flew well, enough to spend a week purchased at the top of a tree in the park lands.

Thanks, I have just been re-reading your contributions on the early part of this thread about your Drobek. Was your second fuselage just less dense wood of the same cross-section? I don't know where I can get 3mm square at the moment so I'll just have to use 1/8 in with enthusiastic sanding I guess.

Just had a look and I've used 3?32 longerons and 1/32" sheet for the nose.

I wanted to take a second to thank Mark for hosting this postal yet again, and throw my hat into the ring as a participant

This will be my first Coupe and first large rubber powered model.  I am going with Batiuk’s “CDH” as found the plan gallery, with the prop from “Dwarf Dip”

Fuse is pretty much complete, less covering.  With the noseblock, but no prop/hub it’s weighing in at 16g. 

I got the Z wire and prop shaft bent and soldered, and am going to get the prop blades formed next.  While those are forming I’ve got a nice piece of 1/32 C grain that will be turned into the 30 under cambered wing ribs needed for wing construction.

I’ll keep record of my progress and share as I get things done.

I've done the wings for my Drobek, about to start the fuselage and probably the prop simultaneously. The drawings I have are low resolution and I can't really make out much detail of the hub assembly. dputt7, do you have any pictures of how you did it on yours?

Thanks

Kevin

Hi Everybody,

I, too, want to again thank Mark for hosting this event. It occurrs to me that perhaps a little support for Mark's effort might be in line. Think about it, here is a 32 page thread patiently monitored and participated in by Mark. He coordinates the event and its results, provides friendly dispute resolution and in the end provides and ships the awards. What a guy!! It's easy on PayPal (friends and family) and would recognise all this effort. Coordinate with him with a private message. Mark may humbly decline but give him that chance.

Best,

Bill

Does anyone know if there's an index for Modelar? I ran across a couple of coupe plans, which I think are from the 1960's, called Coffee and Jupiter. If they'be already been mentioned in this thread, please forgive me. They may or may not be my cup of tea , but I think more choices are good to have. I hope I recall the names right. There does seem to be a list of the year's plans in each December issue. Kinda need tiny little eyes to read it.

 Kevin, the wings look great, sorry for the late reply but I've been away on Holiday for 8 days.
Yes my copy of the plan was very blurry, is photo 1 the plan you are using.  Photo2 is a photo of my plan enlarged. The blades I laminated them around a can and set the pitch as stated on the plan. Photo 4 and 5 are my interpretation of the hub. HOPE THIS HELPS.

Thanks very much Dave, those pics of your prop are very helpful. Yes, I'm using the same plan. Hope the hols were good.

December 1 is the opening of the 2020-2021 postal competition window for competitors in the Northern Hemisphere.  This window will close, as always, on March 31.

More Progress on the CDH.  Stab and wing are ready to cover, and I’ve got the prop hub and blades together.  I didn’t trust that I could drill the blades properly for the wire hub and get the fold right, so opted to drill some 3/16 dowel rod, install on the hub, then glue the blades to the dowel in a pitch setting fixture, much like an indoor prop would be built.  It worked great and the food is as good as I could have asked for.

 Covering and final assembly to occur shortly.

I am going to build the New 1954 Etienvre CdH kit from Hummingbird Model Products. Hope to get her done before the end of Jan so I can get my flights in during the calm winter days that always show up in Feb-March late winter here in Alberta.

Bernard, The title of this thread is "1960s Coupe d'Hiver Postal" so the Etienvre is unfortunately not eligible.

If you look at the FFQ coupe survey 2006 you'll see that although the MichEt was first flown in 1954, it wasn't drawn up till some time (years?) later. Who knows when that was, perhaps you might like to contact Bernard Michaud and ask him. We've had this conversation (not you and I) since the 60s coupe postal began and I thought it had been resolved in favour of allowing it.

Oh! I hope you are right Peter, then I can enter and probably persuade two other club members who also have Etienvres to do likewise.
I hope that Mark knows the answer.

How can it be both a vintage coupe and a 60s coupe?

...if it was published both in the vintage period and the sixties...the low winger, "Ailbass" qualifies for both for that reason. Not convinced about the "etienvre" though.

I don't understand that. Surely once it's been published, that's it. The Etienvre was in Aeromodeller a couple of years ago - does that make it a modern coupe?

All the vintage coupes as published by Modele Magazine and the 60s variety (with the exception of the full sized drawings in the '60s Aeromodeller) are reduced size. We take an enlightened view of when they were built.

We seem to be talking about 1954 coupes being entered in a 60s coupe contest. I'm obviously missing something so I'll wait for a ruling from Mark!

No need. The source plan is in Vol Libre page 9291, and Bernard Michaud explicitly states (in French) that the plan is drawn directly from the model in 2003, which still exists in flyable condition, and is of a 1954 origin. It therefore qualifies as a vintage coupe on SAM rules, but not as a 60s coupe, unless someone has other info. Ed Bennett clearly used this VL plan to prepare his full-size plan of the model.

There are plenty of 60s designs for the Postal, without fudging the boundaries, in my view.

Are back numbers of Vol Libre available anywhere?   I have searched for on line scans many times with no success.
