Very nice! Congratulations.
The Su-7 (Nato "Fitter-B") is something barely known to most Westerners. Your model flys well; ........and has a long takeoff roll just like the real one!
More details? Dimensions, power system, construction?

Very nice.

Great to see this being modeled. Very similar lines to the MiG 19 I'm doing now. Almost decided on doing the Su-7 but had better drawings of the MiG.

Good flight too. I'm guessing that was the maiden?

Guys, thank you for invitation!
So about SU 7. Material is foam plastic(one of the tipes) dark blue. it was a slab of 10 cm thickness.
A pair of tubes and rails of carbon...Stationery tape.

Wingspan 850 mm . Length-1400 mm. All-up-weight is not more then 2 000 g.
I used 3 positions of the airplane for 3D model in SolidWorks.
The power plant
I use 2 Kw motor and equipment suitable for it.
The main task of process was designing of the air channel befor and behind of fan.
You know fan must to recive enough of air.
My fan has over then 2.5 kg of thrust. I wanted to keep this parameter
Please have a look at the process of building in the foto

Very unique project . I'm going to have to come up with a duct similar to that for my Het mig 21. If you squeezed the round FSA of the duct flat where the lipo sits , would it still flow the same or would you have to widen it even more ?

Sorry i dont understand your question very well.
As for air channel befor fan.
In any vertical profile of the channel we have the same area=Intake area(nof FSA).
And under lipo the air channel is changing its form only. However,any vertical profile in this part has the same area=Intake area.

Could you show your MiG21 please?
