The DA-120 is a computer designed high performance model aircraft engine. One is convinced at the first glance with the superb finishing. The cylinder, piston and crankshaft have been designed exclusively by Desert Aircraft and produced by specialist companies.

With the DA-120 it has been possible to develop an engine that has the power of a 150cc engine and the weight of a 100cc engine. In comparison to the DA-100 is the DA-120 175 g lighter. The lightweight cylinder of the DA-120 with the thin cooling fins and details such as the Titanium propeller shaft allows the low weight without compromising the structural integrity.

The reed valves developed by DA plus the Walbro carburettor are perfectly adapted to the engine giving an even running engine in all attitudes and throttle settings. An aluminium throttle arm is fitted to the carburettor throttle shaft.

As is with all DA engines the DA-120 has been factory test run, the carburettor needles adjusted. The world wide DA service and support is unique.

The DA-120 is the ideal power plant for your model in the 120-150 class.

Original DA Fuel Dot “Tankcap with DA-Logo”

The DA Fuel Dot serves as a cap for filling the tank. Very neat and workmanlike appearance.

The cap has an O-ring which holds it in the bezel. The red anodised screws have an English thread and these must be screwed into the fuselage wood covering as a self tapping sheet metal screw would be.

Diameter 34 mm, Weight including screws 16 g.
