The power unit was radial engine Walter Pegas II-M2 (Bristol Pegasus engine license), not Walter Sagitta (Walter Sagitta was an air-cooled inverted twelve-cylinder fork engine).
The power of the power unit was nominal 520 hp (382 kW) at 2000 rpm, starting 580 hp at 2300 rpm and maximum at an altitude of 1900 m 610 hp
It was armed with two fixed machine guns vz. 30 caliber 7.92 mm in the lower wing (400 rounds per weapon) aimed pilot and movable double machine gun vz. 30 caliber 7.92 mm on a Škoda Šu-31 carriage (12 drum magazines with 70 rounds each) for observer. The load of bombs was up to a total weight of 350-500 kg (eg 5 by 100 kg)

Letov was formed out of the Czech Military Air Arsenal and the design team was lead by Alois Smolik, and it was this team that was resposible for the 328 and the later 528 of which only five were built. The basic model was the widely produced reconnaissance bomber, but some were finished as the 328V twin-float plane and some as the 328N night fighter. The first 328 was ordered by Finland, a one off 328F, but this was not delivered but the Czech Army Air Force ordered the 328 to equip it's reconnaissance squadrons. By the time the Nazis annexed the Sudentainland more than 445 had been delivered. They were impressed into the Luftwaffe or the new Slovak Air Force and used in the invasion of Poland. Even after the German invasion production at the Prague-Letany works continued the final 30 entering service with the Bulgarian Air Force. I would say the performance figures noted above are more reminiscent of the 528 than the 328
