I got the 3 plastic parts - Turtle Deck, Canopy, Cowl from USA. Rest is scratch built here

The wing is foam core with balsa sheeting. Cores were cut with hot wire

This model is being built without plans!

Working with the build manual, and some photos/details found on RC Universe

Wing sections joined



Centre portion reinforced with Glass & Araldite

Fuselage is in Corro, wings are foam with 1.5 mm balsa sheeting, and tail feathers are 6 mm Balsa

Thanks Mehul. Still a long way to go!

I considered using 3 mm balsa sheeting for the fuselage. But after some consideration, I realised it would add about 150 grams, a lot more work, and Corro would work fine

Plus, if I don't use some corro, it would be OoC  ;)

Haha.
Try to guess.
Here's a clue. "It has reference to the context"

As soon as I saw Rai saheb's post, I began waiting to see who would be the first of many puzzled members to seek clarification  ;D

Lol Iyer sir! Prabal, OoC is "Out of Character"

Wing is held down by dowels in front, and bolts at the back. Before gluing in the formers I fixed the Dowels, as later there would be no place for the drill once the fuse was assembled

A part of life

Not dependent so much on quantity of models, but on how they are stored, and how long they remain idle without being flown

Need to make a balsa piece for the lower fuselage front.

Supposed to be carved out of a 1"block, I fabricated one instead by gluing strips

Fuelproofing. Ordinary enamel paint

Wing tips made

Original design suggested carve out of a 1 1/2"X 1 1/2"square bock. I chose to make a fabricated (built-up) tip
