dual control. There was a baggage compartment behind the rear seats, accessible from inside. Photographs show that access to the cabin was through a single, port side door. The date of the first flight is not known, but by the July 1937 Prague Aero Show it had been flying long enough for the directional control problem implied by the revised empennage to have been both recognised and addressed. It is also not known when the undercarriage was altered. There is a report from March 1939 which says that the E-210 was then in production, though March was also the month of the German occupation of Czechoslovakia, so it is not clear if any further aircraft were completed. If so, they or the prototype may have been used by the occupying forces as transports, or following Flight's suggestion, as Army Co-Operation machines. Post War development: Praga E-211 An E-210 was at the first post war Paris Exhibition in late 1946. Praga continued development and in 1947 produced the E-211. This used the more powerful, 105 hp (78 kW) Walter Minor 4-111 engines and had a central fin in addition to the endplates. It had the tricycle undercarriage of the earlier E-210, but was now described as a 4–5 seater and had better access, with a starboard side door opening onto the front seats and a port side door for the rear seat passengers. The door revisions brought in train some changes to the side glazing of the cabin. Fin and tailplane were covered with fabric, in place of the plywood covering of the E.210. As far as is known, only one E-211, registered OK-BFA, was built. There were plans for a light freighter version of the E-211. Also planned and under construction in late 1947 was an 8-seat development, the E-212, but it may never have flown. Variants E.210 4 seater, powered by 2x Walter Minor 4 engines, flown in the late 1930s with limited, if any, production. E.211 A 5-seater developed version emerging in 1947, powered by 2x Walter Minor 4-III engines or 2x Praga E 8-cylinder horizontally-opposed engenes. E.212 A planned 8-seater enlarged version, not proceeded with.
