This one was also designed and tested by the MAI, but I don't know the specifications and history.
Is there a 3V drawing available?

1976 V. Kuznetsov drafted sport aerobatic aircraft "Photon-01" diamond-shaped wing. The aircraft is now intended to establish a piston engine M-337 260 hp with a tractor propeller.
