HI,
I look for a better 3-view plan of Technoavia (Interavia) SP-91 / I-3 / E-3 that I have for CAD drawing and making an RC model.
.

I am looking for TECHNICAL DESCRIPTIONS OF SP-91.
Here is an amazing aerobatic flight of Larry Schlesinger's SP-91 and the music is excellent as well.

I have found two useable drawings.

In 2012, I bought a used SU-31 model and I had a lot of flights with it.
Wingspan: 2395mm
Motor: 3W 80ccm Twin-cylinder
Propeller: Bambula 26x10
Weight: 14,5Kg

Unfortunately, this model was a little bit heavy.
I plan to build an SP-91 single cab version model, scale M1: 3.
I hope this model will weigh less than the previous one.

JOZSEF

Unfortunately, I didn't get any drawings of SP-91.
I started to draw the CAD drawing of the model.
Wingspan of the model: 2700mm.
.

JOZSEF

I plan to use the NACA 0015 and NACA 0012 profiles in the wing.
Or do you have any suggestions for wing profiles?
.

I have finished the elevators and the rudder CAD drawings.

so its your final decsion that you will build this airplane...

JOZSEF

Yes, of course.

Could anybody help me to make the canopy for this model?

I am not an experienced CAD drawer, but I like drawing in the SOLID EDGE.

I have just finished drawing the first part of the 3D of the SP-91scale M1:3.

I redrew the aft part of the canopy roof because the previous drawing was not successful.

These pictures were taken by me in 2005 when I decided to build this model one day in the future.
Do you have any suggestions for the construction of this model (picture or drawing)?

Do you have an idea for installing the main wheel? (picture or drawing)
Has anyone started building this model and cabin roof template scale M1:3?

My modeling friend Attila Tóth, who is an experienced SOLID EDGE CAD designer, helps me a lot.
A few years ago he had made this EXTRA-230 CAD model drawing in SOLID EDGE V20 than built it.
This CAD drawing also inspired me to create my own CAD drawings.

I think of another possibility of connect the wing to the fuselage, like TONY CLARK's CAP-21 model.
