Nice! This BTW was my first "Box Fuselage" build, somewhere around the late 1960's :)

@gaurang.1972
Looks great.
Like Sanjay sir, I built this some 50 years ago.
Please check two things:
1. That the prop is balanced. (Vibration visible)
2. Left wingtip seems to have a lot of negative incidence.

Looking forward to more details, like motor, gearing, prop size, battery, total weight, RC or freeflight etc.
Also wether you doped the tissue.

Well done so far. Best wishes for test flight

Good luck with the flying. As a glider, I vaguely recollect once the CG was set it flew quite well.
Where do you get acetate sheet? Does it go by any other name locally?

@sanjayrai55 sir,
I used to use used ( ???) xray prints and OHP transparencies...
If I remember correctly, acetate sheet is the one that dissolved when Quickfix was applied  ;D
