larryross, thanks for creating and posting plans. I printed everything out and will start building as soon as my depron shows up.
the props are GWS 8060 SF
the battery is an 800-1300 mah 3S
the tank weighs about 6 oz
the CG is about 1/4 or 1/3 of the wing length, it usually changes as diffrent battery/cargo is loaded It dosen't seem to notice the changes.
Best regards , Hasse

Any interest at this time in exploring the possibility of doing a Twins Cargo 130% template in see temp?
|Oct 29, 2012, 07:34 AM|
The move is stalled as CLOSING is not until Nov 9.
Then I will have to get all my stuff organized in the house and shop.
I am still hoping for an Early Dec start up ( assuming everything traveled well.)
I have now spent 4 days driving across country
and the balance with 4 and 8 yr old grand kids.
SO , ummm , Refresh my memory ... Where do I get this template material ?

and a bit later ...
OK I found it at seetemp.com !
I will still need to TEST the stuff for machineability.
My CNC is Router based Not Naser and it'll all depend on Speeds and Feeds.
Routers tend to melt some plastics rather than cut.
The result is a build up on the bit and loss of accuracy as the kerf grows.
I could just do an Ink or FINE permanent marker pass.
Or, spring some bucks for a swivel type Knife like some vinyl cutters use.
Or, I could just cut foam and you could make your own template from them
before putting the parts together.
Seriously If you are going into production with the templates I could
let you have a qty deal as an alternative to all the cutting labor.

Wel, my Twins was ready for her first fly... but it fell down like a brick :S Good thing I only dropped it from 20 cm from the ground, so nothing has broken
Still problem is my plane won't fly..
At the moment my plane lie by a friend, so I can see what kint of electric is in it, and what it weights. But I guess it is around 0.85 KG,I guess i have a 800-1300 lipo with 3 cells, 2 speedcontrolers and 2 brushless motors. I don't know what type and other details around te motors, only thing I know the are orange and they dond make my plane fly.
I don't know or it makes any difference.. but the motors and de speedcontroles were meant for a quadrocopter, so does that explain why my airplane didn't take ar?
the stupid idiot I am,I already ordered new motors before vigerend oud what kind of sc and battery I have, and or these motors will work on my plain.
So the new motors are from TurboJet and there are blue
C2822 Brushless Outrunner Airplane Motor 1400kv
Wire Winds: 25
Idle Current(A): 0.7
Cells Ni-Cd/Ni-MH: 6-12
Cells Li-Po: 2-3
Shaft diameter/mm: 3.175mm
and this is the prop I use
and of course there will be two of its. Wil this make my Twing fly?

I do use a sheet of FFF as a spoiler board. Spray mount the SeeTemp to the spoiler board, ( I use a mist coat of Elmer's spray glue) and you don't need tabs when cutting the SeeTemp. Really nice when using as paint masks as no matter how neat you try to be cutting out the tabs, they show up in the paint job.

rcav8r2: thanx for the Speeds and Feeds !
I have a custom adjustable Vac table , so no problems holding the stuff down.
Any clues as to "WHAT" See temp actually is ?
I'd sooner buy it in 4x8 sheets from a plastics supplier, now that I am back in the Midwest.
BTW: Home CLOSING Tomorrow and Moving this weekend. wheew, seems like forever
yet it's only been since mid Sept.

Maybe check with a photography studio, or TV studio?
|Nov 08, 2012, 12:51 PM|
I'll check Laird or just surf for it.
On the other hand ...
I seems to me that
1. the thinner, more scribe and snap type of plastic is good for modelers who wish to make their own template. AKA seetemp
2. a thicker more resilient/tougher material might be better choice for a CNC template making operation.
End users would get a better more long lasting product.
Noting the ~.1" thick templates that draftsmen "used" to use. Of course those were molded.
Acrylic, polyester, mylar plastics all seem to be indicated from my searching to date.
Frosting is NOT necessary IMHO.
I would consider colored clear material as a compromise to the frosting.

I am eagerly awaiting the maiden flight of 'Magnus', my cargo plane.
I would like to thank Foam & Tape for a brilliant design. I have really enjoyed the build and hope he flies as well as all the others!
Here is a picture. What do you all think?

Anything thicker (more ridged?) may be harder to roll to put in a mailing tube (cutting down shipping cost) The SeeTemp will roll nice and tight, and only have a slight curl after taking out of the tube. Certainly not enough to worry about when using them. I store the templates rolled up with the plans in a mailing tube with no problems.
Just my $0.02

Great looking Twins Cargo
|Nov 12, 2012, 11:17 PM|
I forgot to ask. Do you have counter rotating props? Or are they both turning the same direction?
I've got a pair of these just waiting for a giant build.
