Hey, in looking at other forums... I found this stuff:
http://www.industrialpolymers.com/st...FQyVFQodZ17y2Q

I don't think it's flexible, but it sure would dress up a foam model to a level par with any ARF.

More info from the seller (copied from the phlatforum.com)

Dear Frank,

We greatly appreciate your comments and suggestions.
We recently discovered that our product is being independently repackaged and sold on web sites for EPS foam airplanes. One of the sites and their videos can be viewed at http://www.wowplanes.com. The owner of the web site has also developed a water based sanding sealer for the foam made by mixing water putty, plaster of paris and our Styroprime sealer. He has several videos on the web site.

Pricing for the StyroSpray 1000 is $52. 38 per gallon. It is sold in 2 gallon kits, $104.76 for the 2 gallons. This product does not contain water or solvent, so your coverage will be much greater than other coatings you are using. A gallon of water based paint is usually about 40% water. A gallon of house paint which costs $35.00 actually costs $49.00 when you factor in the lost water which evaporates away. With StyroSpray nothing evaporates away. We do recommend a heavy coverage of 50 to 60 square feet per gallon for outdoor applications.

The weight of this product is 9.21 pounds per gallon. If you apply 1 gallon per 50 square feet of surface area as we recommend for high durability applications, you will cover 50 square feet, 32/1000 of an inch thick. If I divide 9.21 by 50, each square foot will have an additional coating weight of .1842 pounds. I think it is possible you will apply our coating thinner than this, so I will say this is likely the max amount of weight you will add. .1842 pounds is equal to 2.947 ounces of added weight, per square foot of surface area.
I do not know how many square feet of surface area one of your air planes has.

Thank you for inquiring about our products. Please let me know if you have more questions.

Best regards,

Hansjerg, those look great! I'm so envious!
Does the EPP airframe absorb any shock on landing then?

Great job!

Retracts Testing

Ok ... I glued the inner wing sections to the fuse and pre installed the gear servo.. As this is real speed ( no retarder) I think I don't have to buy one...

Hello Pete!

The grass is not my job... I got the " brown thumb " of my family as whatever plant I touch dies within some weeks ( I like those bonsais that much but as expensive as they are ...you wouldn't believe how fast I burry them....

BTW: I bought myself a new cam for Xmas and I'm very glad with it... the details you get using optical 12 MPIX are superb..

BTW.: not much progress on the plane today .... I hinged the ailerons and next I will cut the servo pockets for those....

It is rather time to choose the setup!

I put my eye on this Motor: 18T

http://www.parkflieger.eu/Scorpion-S..._1493_298.html

or on this ( here the 22 Turns version, for not to fry the controller)

http://www.parkflieger.eu/Dualsky-BL..._1178_167.html

and this controller

http://www.parkflieger.eu/Scorpion-C..._1635_305.html

But they are both rather expensive compared with the HC products

I also would need 4 mini servos 15..20 Gram ( usually I take HS82 for this issues but if there other recommendations... ( also for the motor and the ESC????))

I have the Scorpion 3014-22 on a 45oz, 60" Me-109 foamie. It's well underpropped with a GWS 12x6. Really wants 4s. Nice motor though.

Beautiful job on the retracts.

I have never gone near retracts since my club field breaks them on a regular basis. The pics of your fabricated retract system looks like they would survive even at our field!

Don ... As the retracts are made from Aluminium and steel for bolts and screws it became rather heavy ( 48 Gram / Unit + Rod + Wheel..) but this would also keep a 2 to 3 KG plane on the wheels!!
