Now the RMI-5 is an interesting beast, in that it was the first and so far the only 4-engine machine of Hungarian design. On the outside, it was modelled very much on the lines of the German Fw-200 Condor. And because of that to answer Tzoli's question, it would have probably met with similar problems if it had been put into a more militaristic role than transport. The reason for the RMI-5 dated back to 1941, when the Germans and Italians stopped the delivery of the transport aircraft to Hungary. Two of the requests at that time had been for examples of both Condors and further Ju-52s. This led to the Aeronautical Institute being entrusted with developing its own transport machine. Power for the new aircraft was to come from four Argus AS-411 powerplants, producing 480hp, examples which were manufactured at Waggon, Győr. Professor László Varga and his team set out to build a state-of-the-art, large-scale metal transport machine based on their experience of the earlier RMI designs. It was expected that the RMI-5 would have a passenger capacity of 20, only five short of the Fw 200 which had been expected to meet MALERT's (MALEV's ancestor's) vision. As previous designs, modelling and technological experimentation were carried out with the Hubert & Sigmund factory in Kőbánya carrying out tensile testing of the main fuselage and its structure. The metal shell wing was designed with a through-through main spar, the undercarriage was made with the well-known ring spring system, and fully retracted into the interior of the engine gondolas. Construction of the machine was advanced, and the core model was ready when the Ferihegy Experimental Workshop was bombed and destroyed in the 1944 USAAF raid.
