Hallo Friends.
Here is my second entry for this Sweepstakes. Making Pitts S1 from coro. Plan downloaded from rcgroup.com.
Wing = 700 mm
Fusage = 600 mm
Electronics doesn't decide. Depending on weight of model.

Challenging build 

It'a great flier 

Friends.. Print out the plane but now scale is big. I want to make little big size model. So now..
Wing : 1050 mm
Fusage : 850 mm

Thank u Sanjaybhai...
Making Wings first. Cut 2mm coro from plan. Its ribs from 2mm balsa.

And first colour the wings....

Very good titil saras

Very Nice...
Carry on...

Thank you gaurang.1972 and runik4...
One Wing is ready...

Both Wings are ready..

 

What thickness corro? And the ribs are balsa? Thickness?

Taitil great going and good tech to mix coro & balsa.

If i see closely both upper and lower are cut same size which is y the upper coro is bit small or it was planned that way?
Any aileron in this plane?

nice build! how did you color the coro?

Vinyl stickers

Thank u topalle rastsaurabh..
Sanjay sir, the ribs are made from 2mm balsa. And use 2mm coro. In first wing, i used double 2mm balsa in middle and in second wing, light weight 12mm aluminium rode. Total weight for two wings with two 9gm servos is 295gm. Not vinyl, I use regular 2 inch sticky  tape for colour. See closely.
Yes Saurabhbhai i cut same size coro. I put servos in lower wing for Aileron.

 Out of curiosity what are those pink yellow material at the background in Weigh scale picture??

Is it Foam  

Yeah I think
They look like those foam floaters that are used in swimming pools by kids 

Very nice..

Thank you Very much Suyash, swapnil, Anant and Sanjay Sir...
Yes sir, when you first told me that this is Challenging build, i thought it would not. But i realise that this was really challenging build. And now i m very happy to made this. I made little mistaken in lower wing. I used very thin balsa stick. So wing gone little bend while flying. Now i give it stick for supports and make it strong.
