Note this might have been just a private design by the same students, not entirely affiliated with Riga Aviation Institute, since it doesn't carry the "Riga" prefix in the designation.
Chronologically, The Chaika-1 (Seagull-1) was built after the Riga-50 and 59. The Riga-AS-2 was built shortly after it, followed by the Riga-72.
Thanks for the additional details. I will keep it in the list until it can be confirmed a private design.
