Spell CITABRIA backward. Yes, you got it!  ;)

I've never built a real foamie, just 3 FT Depron models. Always been suspicious of that darn thermocole  :rofl:

Well, at the end of the build, I am more suspicious than ever  ;D Disgruntled too; and a couple more which are not meant for this forum  >:D >:D

Brief Specs:

From an outerzone plan for balsa, roughly adapted

54" span, AUW about 850 grams, used a 2836-1100 Motor with a 10*6 prop, 2200 mAh Lipo

sanjayrai55

Thermocole from a stationery shop. Used 10 mm and 20 mm

sanjayrai55

Used Fevicol, and Epoxy

sanjayrai55

Fiber Tape used for hingeing

Sarabh Rastogi gave a good idea to use Gauze bandage as a dihdral reinforcer. When I was 12, about 46 years ago, would use silk ribbon with Tradfix balsa cement  ;) ;)

Used some scrap foam board for Ailerons.

Reinforced the nose for the landing gear plate

sanjayrai55

Used a piece of hard balsa as the L/G plate

Bent a 3 mm pushrod to make wire landing gear

Battery platform made

sanjayrai55

Colour tape used, with a base of masking tape

WOW! In such a short time,i barely just develop the design in my mind and outline it on the foam!

How do you keep this themocol from crumbling into small pieces and balls?

Thank you Saurabh. Frankly, it is one of my poorly finished models. I did not find this material amenable for this kind of build.

Form follows function - there was a mismatch here

sanjayrai55

Topalle, it does crumble while building. After, the tape etc. keeps it in place

Very nice build sir. I saw this thread twice. Once I avoided speaking since, I'm a beginner but couldn't resist since I'd done this many times on all my foam models.
Just a very small suggestion :bow: :bow: :bow: :bow: I want to suggest you please iron this model. I mean pre-heat iron for 10 seconds or less and iron whole model with it applying gentle pressure. In this model seems to be normal transparent tape for lamination and coloured tapes for design. I'm sure you would love after it.Very clean finish.

P.S. Please try once on a sample piece to check heating required on this material/tapes.

Very nice build considering that you have used thermacole. What have you used to cover the foam? Looks like lamination sheet.

I am stuck trying to build the wing with biofoam for my Cessna. After junking two biofoam wings and lot of head scratching, I have finally decided to build the wing with traditional balsa. Hats off to you guys who can build large models exclusively from foam.  :hatsoff:
