Title: A quick build without any plan
Post by: johnywalker8pm on February 21, 2014, 12:31:03 AM
After my first flying session with Mr. Moorthy and V2 eagle, build it without any plan with a foam sheet. still wondering what glue to use in this material.
Any suggestion ??  :headscratch:

few build pic attached, with the cutting tool set up.  ;D

Epoxy. commonly known as araldite.
Takes time to stick but dont attack this foam.

Use hot glue or 5 min epoxy....
well, either the vertical stab is slightly big or the wing is small in length.

use rubber based glue... you will get solid joints...

First clean surface with Petrol ( which has no oil mixed)

I agree with sandeepm sir.
Also, though the model is built neatly, still, does this material has sufficient strength to survive in air. Since, what i could make out from the pics, this is the one used in packing of TV, refrigerators...

I also don't no the name of this form, may be EPS ( correct if i am wrong ).
But i have tried this, This has to be strengthen with Spar, and covered with Polythene or any smooth surface. The Bare surface will restrict airflow, and stop your plane moving forward.

 :thumbsup: give it a try.

@ manojswizera ..

even i think so.. need to cover the surface for smooth air flow..

Expanded polyethylene or EPE foam, I think.

@sandeepm

yes.. the wing span is 8" smaller than the actual.. i checked it in a pdf given by Mr v2 eagle.. now i made a new wing with correct ratio.. i will post pics once i fit all the electronics.

If it is EPE then its has excellent fracture resistance its resilient but very bad thermal and scratch resistance u need to coat it with something
