AIXRO Wankel XR50 engine

Reliable engine that weights 18 kilograms and has 50 HP at 8750RPM? That is all possible thanks to Mercedes-Benz sponsorship for Wankel engine kart programm and AIXRO Wankel XR50 engine was born. With outstanding characteristics like high reliability,  high power to weight ratio, no vibrations makes them especially suitable for installation in aircraft or oder demanding applications. Based on XR50, Gilo Cardozo developed Rotron engines capable flying at 9000 meters on GKN mission above Everest. That are very good news for motoparagliding society and ultralight builders. The only obstacle is the rpice which is around 4500 EU ready to fly.

    Would love to by one for my new Earthstar aircraft that I just finished, but now need a engine to complete. How ever the price here in U.S. dollars is way out in never never land.I don’t see how you will be able to sell many engines here in the U.S.A. at $8500.00 and that doesn’t include the radiator.

    You’re confusing the Aixro XR50 and Aixro XF40. The XR50 (as pictured above) can produce an amazing 44 hp and weighs only 38 lbs. Unfortunately, it can only do it for 10 seconds at full power. That’s only good for race-course Karts.

    Aixro does make a continuous full-power engine suitable for aircraft, the XF40. Unfortunately, it only produces 35 hp and weighs 56 lbs complete. But that’s what it takes to produce continuous power.

    When this post was written XF40 does not existed or just came to life. Few friends ordered XF40, complete with 3 blade Helix prop. Very good piece of engeneering. Cheerz!
