EPP SU-22 Fitter

Hy everybody,

just wanted to share some pics of my recently finished SU-22. OK, shes no pusher but I think she fits in here best.
She is made of 20mm(fuselage) and 10mm(aerodynamic surfaces) EPP RG20 (20kg/m) with 1,5mm carbon rod reinforcements. Armament is mounted with 2 pieces of 10x5x1mm magnets each and removable for flight.

Some tech data:

span: 930mm
length: 970mm (1090mm including Elevator and Spinner)
area: 19,6dm
fuselage diameter: 97mm
weight: 570g

Tailerons: 2xHXT-900
Rudder: 1xHXT-500
Motor: Turnigy 3530B 1400kV
Akku: 3s2200mAh Flightpower
RX: GWS 6Ch

First flight will be together with my YAK-130 when it stops raining in Germany together with my YAK-130.
Hope she flies as she looks

mr ud- that looks great!! are the Su-22 and the Su-17 sister ships? i was working on an Su-17 that has stalled out a bit. but the lines look extremely similar to the Su-22 that you have here. excited to hear about how she performs and where your CG ends up. is yours swing wing? good luck with the maiden!

Hello beanie,

as far as I know is the main structure of the SU-17, SU-20 and SU-22 almost the same. The SU-20 and SU-22 are export- versions of the Su-17. Changes were primary made on engine, armament and avionics and small changes on Canopy and back. All drawings of the three birds that I have found were almost the same - but I cant guarantee

I was testing the CG before installing armament and electronics (~250g) and had to move the CG about 20mm back from the calculated position for a nice glidepath. Lets see wether the CG still fits with more than twice the weight and a powerfull engine in the nose.

PS.: still raining in Germany

That is going to look GREAT in the air! Even better than if it were a pusher with a motor hanging off of the back.

I hope it flies as good as it looks!
