Bargle,

A sheet 19 & 3/4 x 26 & 1/8 weighs 6 grams. How that compares to Esaki, I don't know. I don't have any at the moment.

Last sheet of esaki I had came in at 4g. So about 2-2.5g lighter than Hallmark.

Skyraider,
What size sheet of Esaki weighs 4g?
If it's standard size 18" X 24" then I want to buy some of that.
Thanks,

Dave,
owner of about 80 (eighty) sheets of Esaki tissue weighing about .008g/sq.in.
Weight varies slightly depending on color pigment.
Very old PECK 'domestic' tissue weighs about the same as your Hallmark tissue.

Dave,
    I no longer have the whole sheets. But I do have 2 -  6 x 24"
white # 0615 Esaki strips  and 3 - 6 x 12 that would make up a full sheet
plus a little extra. Weight comes in at 4g.  My box says lite - Flite # 0615 White.
Tissue count was 100 sheets ( 50 per box ) @ 3900 yen back in 2009 and
I used to get my tissue direct from Hiroshi Esaki. I use to also order the OD Green
but never got a chance to weigh it out.

Germany is a black hole as far as Hallmark tissue is concerned.  Tissue seems to be almost totally unknown here with the exception of the stuff found in shoe boxes until fairly recently with two shops offering Esaki for a rather exorbitant (but at least available) price.  A BIG artists outlet in Frankfurt has a good supply of 10gram TENGUJO with 5 gram on special order (no Esaki).  My LHS does have the heavy "JAPICO" tissue in blue and white - weighs something like 16-18 grams/m².

I had weighed the shoe box stuff, and posted it somewhere compared to yellow Esaki.  It WAS heavier, but not by that much.  It did require more dope as there were obvious openings in the fibers (holes) and is very brittle when doped.  It also has a very pronounced texture - sort of lumpy - that doesn't completely go away after shrinking/doping.

EDIT: I weighed the sheet that I had printed the lozenge pattern on (11 x 14 inches - printed coverage = 95%) at 1.93 grams.  The WHITE, unprinted sheet was 1.83 grams (about 0.012 grams/in²).

9 & 10 gsm tengujo tissues are usable although 6 and 7-8 gsm provides lighter results. I am currently experimenting with 5 gsm tengujo I got from Horomi in the US. It is not for the faint hearted because it is more holes than paper fibre. The jury is still out as to whether or not 5gsm results in a lighter covering than 6 or 7 gsm.

6 gsm is also full of holes but appears to work with traditional dope/polyurethhane brush coats, ( I do not use that technique unless I need a last shrink coat and then I only use a clear acrylic ink (no pigment)). 7gsm will accept brush coats but be careful with dope; the tissue will shrink very strongly.

The best examples I have ever found of 'domestic' tissue are also in the 16-18 gsm range.  

A while back you mentioned a lack of supply of dope in Germany. Randolf dope is supposed to be available in Belgium, if you are prepared to venture that far.

A little earlier I weighed a sheet of dark blue FFS (Woodhouse) Esaki LiteFlite. It came out at 3.48g for a 44.5x60cm sheet (approx 17 1/2" x 23 1/2"). This equates to 13.03 gsm which is close enough to the usually quoted figure of 12 gsm.

Peter,
     That's about what I calculated on Dave's sheet. From the info he gave,
I figured he's in the 3.5 - 4g range per sheet based on the 12.5gsm. The same
( or close to what I have ) weight-wise.

My latest is the Cizek XL-56. I built it from Bob Holman's short kit. Weight as shown is 118g, will probably come close to 125g once I add the missing pieces. Hopefully I'll trim it this coming Sunday. This model looks and feels like a pure bred flying machine compared to everything else I've built, I'm curious how it will perform in real life;).

Now back to my Tsh-3 which was orphaned for a good 6 months...

atesus,
Your XL-56 looks really nice.
I have no experience with Wakefield's from any era but would like to know how much Rubber is recommended for this ship.
Thanks,

Thanks guys!

Dave, I understand that the original model was flown with 80g of rubber. Than in 57, Cizek started experimenting with 50g of rubber. His original plan shows two motor peg locations for the two motor options. I came across a later version of the XL-56, named XL-56b published in Aeromodeller in 1958, which shows an alternate wing location for the 50g motor in addition to the alternate peg location. 

The weight shown on the plan is 240g with a 80g motor. I'm 35g below that, so I'm planning to start experimenting with a 53g (2/3 of 80g) motor, arranged in 16 strands of 40" length. I'll make two additional "booster" motors of 8 strands and 4 strands and add those in as necessary during trimming.

Looks great Monique, I like the colors!

Ates,
Thanks for the info.
I have a small image of the plan with the notes/text in Czech and I couldn't quite make out the Rubber info.
Great job again.

We'll see. It was misbehaving at North Luffenham but luckily the grass was as high as an elephant's eye. Charlie tells me it's a bit short on the meadow. Please make yourself known!

Will do. I've not been to Luffenham this year, but it sounds as bad as Salisbury Plain & Sculthorpe where it's necessary to walk like a dressage pony, otherwise the grass knits itself round your ankles, and over you go.................well I do  Shocked. Nevertheless, I accept that it's good for trimming models.

Do you need long grass at Port Meadow? I thought the standard practice there was to land in a nice soft cow pat.
