no need to add weight by sticking the clot and epoxy on the entire length.  The model is small and not much of wing loading is expected ... even in tight high G turns manouveors it is not likely to breat the balsa sheeting.... the curved balsa sheeting is very very strong and takes the load.  A true semi monocoque structure.

Inspiring build   {:)}

Never built a balsa wing till now. Feel like building one after seeing this build thread.

Hope you plan to dope the entire Balsa after the construction is over and before the wings are covered.  Do not forget to do the dope as it will give it strength which u will need and also a smooth finish to the wood parts.  More so the structure will be somewhat waterproof.
Nice build

@shobhit17 sir, a real old timer is one who has dope, haha. Where can one still get it? Need some as want to tissue cover a wing.

@jana.f22
Switched from dope (after IHC) to NC Clear (smells and works the same).
Don't know if even that is available any more.
But for wood you can use Asian Touchwood or Nerolac Wonderwood PU.
Remember to put on a super finish. Don't rush it.

Well Dope is actually a Nitro Cellulose (NC) based paint.  Go to any good paint shop and you will have to ask for NC Paint in clear colour.  The same paint used by Car painters which dries in a few minutes.  You will need to add NC bansed thinner about 50% to the paint by volume to thin it to your requirements.
For filler I take some Chalk power and pour some of this thinned paint into it and make a paste.  It dries in a few minutes enough for you to sand the extra one off.  Alternatively you may use any Wall Putty and use it as a filler.  Once sanded well... just apply the dope and let it dry... use a "WELL USED" sandpaper of 120 or more grit to sand the painted surface lightly for a shiny smooth finish.  Even if it does not shine its OK.

I knew this was comming and waiting for it.... ha ha ha... to many people getting cought in the DOPE... ha ha

KK Sir... you can use this Clear NC paint or the clear laquer on the tissue paper covering very well.....

@jana.f22,
Wait, wait!
Before covering the other wing, please take a long sanding block and sand the wing surface smooth.
Start with about 150 grit, finish with the finest you have (300-600).
Don't let the surface irregularities, joint lines etc to show through the covering.
Colour scheme choice is excellent! (Should the star point the other way?)

jana.f22

@kk Iyer I didnt see ur post,  covered the other half sir. I sanded the entire wing with 120 grid. Next time ill improvise sir.

Well Jana.... one more caution.... if you had brushed the entire wood surface with "DOPE" i.e. the NC Clear laquer..... and then used the 120 grit sand paper to finish it smooth..... the wing and the other surfaces (whereever the wood is) would have been smooth and laquer finished.  If the surfaces are small I simply use QUICKFIX on the wood and spread it all over with my fingers and then let it dry.  This way not only you get an excelent finish on the wood surface (even what goes under the covering) it gived the wood more strength and a great surface for the paper to stick better.

Just try it and remember it next time.
