3W-COMPETITION SERIE

We from 3W-Modellmotoren are proud to present a new range of engines, being developed in close cooperation with top international aerobatic pilots. The strong requirements flying sophisticated aerobatic maneuvers had been met.

All parts are selected, pistons,cylinders and carburettor are modified. Cylinders painted: red, 2-cyl. boxer engines with carbon-fiber 90° intake manifold.

ignition system prepared for direct connetction to 2 cell LiPo batterys without using voltage regulator

if you are planning to buildt our engines into any other vehicle than a model airplane please contact 3W Germany directly

you can choose a decompression valve for enginges with cylinders bigger than 2.90 cu.in
