Can we use low dnsity thermocol normally sold in stationary shops for any serious models? (:|~
Saw this at many places....
Is this low density thermocol the one used in insulation of homes? ( ceiling?)

Its not worth the hardwork as its very weak.

You can.
Use fevicol and tissue paper to laminate it. i did my corowing plane under 60gms with the stationary thermocole. joining two pieces with tooth pick.

How did you reinforce the wing? Pushed a cf rod into the thermocol or stuck it?

I make free flier aeroplane (6"-18" Wingspan) covered with coloured tape and having lead ballast weight that glides very well with a slope of Δy:Δx = 1:35. I will post the build logs in different thread.

"Δy:Δx = 35:1"
???

:giggle: :giggle:

BTW Kalyan Da, if y is the vertical axis then that is a very bad plane. :giggle:

'Plane' as in Aeroplane or as in physics?

Plainly asking plain questions - hope you don't mind.

That is Kalyan Da's "free flier plane". Whether it is aeroplane or physics, it is his call. :giggle:

Sorry, mistyped while searching typing code of del.
corrected.

Actually it is the gradient/Slope. Rohit, perhaps you have seen the gliders.
You surely can adjust this to make 1/35 to 35 also by adjusting only the throwing angle. ;D

VC, Sorry to say that you have just brake one rule of using english only, though for fun, but it is...

Brake or Break? ;D

I need your help and will call you later today. 12 noon ok?

Cheers!

Changing the CG will also help. :giggle:

Yes, definitely. as shown in your avtar rohit. ;D

VC, :) some times those unintended malapropisms make English hilarious reading :giggle:. Trying to correct is ok ;) but let the thing be enjoyed when the going is good :P. What says you? ;D No pun intended.

Mine doesnt needs any reinforcement, if i remember correctly its a 30" plane. just make 3 times lamination and its strong and light.

well.... I have used the thermocol used for AC insulation for my 6 ft span Glider (Apple Box). I have reinforced it with 3mm x 6 mm hard foot spars running on top and bottom of the aerofoil. Do'nt ask me where do you get these hard wood spars.... I cut them myself at the local carpenters shop and had used the heavy machinery packing material wood for the spars. For the outer panels I have used Balsa spars of same thickness. OK... I also used a balsa LE and a TE. I am reinforcing it with Coloured masking tape for the finish. The Guppy is a 5 ft span glider and I am giving only similar Balsa spars on the inner portions but have left the outer panels without any spars. Yes have given balsa (home grown) for the TE and the LE. Will reinforce it also with masking tape.
I have used a 2 inch thick sheet of Thermocol.
You may see my build log for the models... its a bit slow progress but going good.

Hello All, this is a 40Inch wing with low density thermacol...
http://www.rcindia.org/electric-planes/scratch-built-piper-lookalike/msg130296/#msg130296

Card paper on leading and trailing edges and a wooden spar in the center.... result is a light sturdy wing.....

Using low-density thermocol for model making can enhance your projects with its lightweight and versatile properties, allowing for intricate designs and easy manipulation.
