Thank you for your contribution, I will keep it in mind. It happens that in my country not many items are available, so within what I can get I will take advantage of what is indicated, thanks again!

Well, I have embedded some pieces to see how it looks.
What I show there will be the core of force that will support the engine and the upper wing. I am very satisfied with the arrangement of the pieces.
You can also see the fuel tank presented, everything is comfortably healthy.




In this photo I present some lines where you can see how they would mount the supports of the upper wing, something like this ...


Well I just start dreaming about Pitts and I have put in templates to imagine it

Looking Nice !! I am sure you will do a good job as always on the looks of the Pitts!

What engine are you going to use?

Thank you! ... I have several models powered by Cox engines, including a Biplane, the Bi-Hawk with Cox .049 RC, so I gave a Norvel .061 RC a turn.

some progress...

ohh yes ... it looks like a Pitts

I see in one drawing it calls for a O&R .29 engine is this the size your going for ? Don't see the length and W/S on the drawing . It is looking like a Pitts

Erick, if you see it as a PITTS, then I keep calm hahaha ... it means I'm doing well! haha

Comparison between PITTS and BI-HAWK

PITTS
Wingspan: 29.8 inches (top wing)
Wingspan: 21.02 inches (bottom wing)
Fuselage length: 19.88 inches (including rudder)
Engine: Norvel .061 r / c
Radio: 4 channels (engine, spoilers, rudder, depth)
Weight: ? (in construction)

BI-HAWK
Wingspan: 30.11 inches (top wing)
Wingspan: 25.98 inches (bottom wing)
Fuselage length: 21.65 inches (including rudder)
Engine: Cox Medallion .049 r / c
Radio: 4 channels (engine, spoilers (lower wing only), rudder, depth)
Weight: 554 grs = 19.54 oz

There place the BI-HAWK on the PITTS plane so you can see it graphically

That is a fantastic project, Mauricio!

Thanks friend

Well, as you will see in the next photo, the author recommends a good idea to hold the top wing upright, in this case it is about two independent uprights for the front part of the wing, while the wing is definitely attached so as not to be turned by half of the lateral uprights that connect the upper wing with the lower wing.


calculating degrees of inclination of supports:


I have decided to change the fastening system of the upper wing, including placing (4) four independent uprights, to also hold the wing in the central part from the trailing edge.
I have taken some nimples of bicycle wheel spokes and have reduced them in diameter. These are embedded in the wood, allowing me once fixed with glue, to be able to control the incidence of the wing as desired, (in case it is necessary to make a desired adjustment after the first flights).
You can see the work done there.
A: It is the original nipple.
B: it is the nimple turned (modified) and embedded in the wooden support of the structure.
C: they are holes made in the wood, after having calculated the place of accommodation for the nipples, which eases the structure.

Lovely project Mauricio!

Fuel tank size looks good what is the capacity?

Thanks Brad !! .... my friend, I'm glad to hear from you. I hope that you and your family are well!
The tank has a capacity of 35/36 cm3 = 1.21 oz.

Yes thank you Mauricio and yours, great find on bottle size!

So far all is well, my local area is in a surge we won't hit our peak till
mid March. I have been working from home, looking forward to flying!

friends, as always, I wish everyone is well! ...
Some progress here ...














more progress coming soon ...

You Do outstanding work.... I like the lightening holes in the cockpit

That is as slick as a Baby's butt Did you add the strip down the fuse side  or is it in the plans ?
 
As always it Looks Great my friend BIG Hugs at a distance  stay safe !!

thank you so much for your words.
There is also the possibility of making the cabin closed.
Two options, with windscreen or closed cabin.
I'm thinking if I make a PET and present it to see how it fits.
