Yakovlev 1-7-9-3

hi,
I am surching for plans or drawings about all these planes : yak 1-7-9-3.
I am a french (sorry for my english !) rc modeler trying to build one of these plane at 1/4 scale, with full of details. Structure will be the same as the real plane. But i do not know (never find pictures) how where the (wood ??) rings frame attached on the metal structure. On hawker restoration site i have seen a beautiful Yak 1 in re construction. Is this plane flying at this time ?? I hope i will improve my english in this forum to write a letter to Hawker restoration to have more details and more pictures !!
If anyone has structural pictures, drawings, plans i will be very happy !
Thanks
Fabrice 🙂

Thanks for this answer.
I saw this site. good for plans but not for details.
For the washout i will try some airfoil profiles and values for washout, because of very short wing tip, with airfoild informatic program.

Hello Fabrice, welcome to the forum!

Try this site, the drawings vary in quality but it often has some useful scale plans.

Good luck with the model Yaks, make sure the wings have lots of washout 😉
