Desert Aircraft Engines

DA- 100I

  • Computer simulation designed high performance engine with very high torque output
  • Sensational low idle
  • Very spontaneous throttle response due to the small crankcase volume
  • Crankcase CNC machined from high tensile strenght 7075 aircraft aluminium alloy
  • Long conrod with gudgeon pin located very near to piston crown to reduce side loads
  • Unbelievably smooth running just like the DA-200 4-cylinder boxer
  • Two Walbro carburettors and new design 4 leaf reed valves
  • Battery ignition with automatic advance and retard
  • DA engines are designed using the latest tools and techniques,including 3D CAD and Stereo Lithography
  • Rapid spares delivery and repair service from Germany by Toni Clark practical scale GmbH
  • 3 Years Guarantee* by Toni Clark practical scale GmbH.

Based on the DA-100L, Desert Aircraft developed a very impressive inline engine.
The DA 100I is a computer designed high-performance model aircraft engine. The perfectly balanced and harmonized design of the piston, conrod and crankshaft was achiefed with the help of a computer simulation program. The DA 100I has the lowest vibration levels in it`s class over the entire throttle range.

Because the cylinders fire in succession, one after the other, the DA-100I has a sensational smooth and low idle of about 800 RPM.

The throttle response, as usual with all Desert Aircraft engines, is very spontaneous. This is achieved by the two separate carburettors and the resulting low crankcase volume.
The reed valves developed by DA and the Walbro carburettors are perfectly adapted to the engine, giving an evenrunning engine in all attitudes and throttle settings. Aluminium throttle arms and a connecting rod are fitted to the carburettors.

As with all DA engines, the DA-100I has been factory test run and the carburettor needles adjusted. Desert Aircraft is famous for their first class world wide service and support.
The DA-100I is not only the ideal engine for your high performance warbird, due to its smooth, DA-200 like running characteristics, the DA-100I is also a convincing aerobatic engine.

Fuel Type

BEL RAY H1R / Aral Ultimate 102

We recommend the use of Aral Ultimate 102 and a good synthetic two stroke oil like BEL-RAY H1R.

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.
