</p><p>Linke-Hofmann designed the fuselage of the R.I to completely fill the interplane gap of the widely separated biplane wings. Encouraging data from tests at the <i><a href="/wiki/German_Aerospace_Center" title="German Aerospace Center">MLStG Laboratory</a></i> at Göttingen suggested there would be advantages in this configuration. </p><p>The capacious fuselage housed the crew compartments as well as the four engines and their clutches and combining gearboxes. This configuration offered the advantage that the engines could be accessed in-flight for adjustment or minor repairs.<sup id="cite_ref-flight_3-0" class="reference"><a href="#cite_note-flight-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> However, there were serious problems during development with engine cooling and vibration.<sup id="cite_ref-RennebergWalker2003_2-1" class="reference"><a href="#cite_note-RennebergWalker2003-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>Construction of the R.I was largely of wood covered by transparent <i>Cellon</i> (<a href="/wiki/Cellulose_acetate" title="Cellulose acetate">Cellulose acetate</a>)<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>Note 1<span class="cite-bracket">]</span></a></sup> in the first prototype, R.I number <i>8/15</i>, and <a href="/wiki/Lozenge_camouflage" title="Lozenge camouflage">lozenge camouflage</a> fabric in the second aircraft, <i>40/16</i>.<sup id="cite_ref-Haddow_1-4" class="reference"><a href="#cite_note-Haddow-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>Cellon was used with the intention of making the aircraft partially transparent and so less visible; however, the Cellon reflected sunlight, making the aircraft more visible, before quickly yellowing due to the effect of ultra violet radiation.

The aircraft was difficult to land because of the pilot's difficulty to judge altitude due to the high position of the flight cabin. In addition, the flight controls were mushy due to the warping and flexing of the lightly built wings. One pilot, recalling flying it, called it "not an aircraft but a sickness". </p><p>Although aileron control was sluggish, both rudder and elevator control were considered satisfactory and the unconventional design of the fuselage appeared not to have a detrimental effect on the aircraft's flying characteristics. The anticipated aerodynamic benefits of the tall fuselage filling the gap between the wings were not found on the full-size aircraft.<sup id="cite_ref-flight_3-1" class="reference"><a href="#cite_note-flight-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> </p><p>R.I <i>8/15</i> wings collapsed when the aircraft was at a low altitude, all but one of the crew surviving.
