Our 4.45 m (175 in) wingspan Aichi A3D1 "Val" at the "Mega-Flugshow" Göttingen 2011. The 66,9 kg (147 lb) Val is made of balsa and plywood, except for the glassfibre engine cowling and wheel spats. Steel and aluminum are used for the wing spar joiner and landing gear. The full size World War II carrier-borne dive bomber of the Imperial Japanese Navy had 14,37 m (47 ft 2 in) wingspan and was powered by a 1075 hp radial, it cruised at 296 km/h (184 mph), the max. speed was only 390 km/h (242 mph). The model is available from Valach Motors in various stages of completion, from partly built up to ready for flight with radio and engine installed. In the second video, you can watch the VM R5-420 running on the test bench. Why is Holger sitting on the test bench? The simple answer is that the VM R5-420 produces so much thrust, that despite it's heavy weight, the bench moved forward even with two pallets on top of the table for extra weight. |
