The DA 50-r is a high performance computer designed model aircraft engine. The first glance imparts a very strong impression of the high quality machining. All components, without exception, have been designed by DA without compromise, and are made by specialist firms exclusively for this DA engine. The crankcase is unbelievably compact and very light, only possible due to the single counter balance weight on the crankshaft. . Each crankcase is CNC machined from the solid, using aircraft alloy 7075-T6. In comparison to die casting, a very costly process in time and material. A system that moreover has the advantage of a perfect fit and an absolute correct alignment of the main bearings, plus extreme rigidity and strength. All very decisive requirements for an extremely high performance engine with very close tolerances throughout. rear view of the DA 50-r. The standoff mounts are supplied with the engine. Please click on the pictures for enlargement. The long aluminium alloy conrod plus the gudgeon pin being mounted close to the piston crown allows the high torque to be transferred without undue sideloads. This all reduces friction and wear while ensuring maximum power. The very low crankcase volume plus the intake flutter valves is the reason for this engines high performance. The DA 50-r when fitted with a custom designed silencer system will produce power equivalent to any 60cc engine or even more.. The reliable Desert Aircraft Battery ignition unit has of course automatic advance and retard that makes starting so very easy, ensures maximum possible power. This unit is completely screened. The piston, conrod and crankshaft has been designed with a computer simulation programme. These parts are perfectly balanced and harmonized to each other. In spite of only one crankshaft balance weight the vibration levels are extremely low. The engine mountings reach quite a way forward making this an ideal engine to fit our Hydro-Mount-System. Due to it’s very neat and gleaming exterior it seems a pity to hide this engine under the cowl. DA 50-r with battery ignition ...... #5500
