Aeromomentum Engines

These look interesting. Water cooled Suzuki, new, starting around $7k for 75 hp and 140 lbs. Low fuel consumption. TBO = 1200.

They don’t list any Sonerai installations to date.  Anyone have experience with this?

Not me. The shape - tall and narrow - would be a tough fit for a Sonerai. Anyone using this engine should figure on making his own cowl or significantly modifying the standard one.

Comparing the dimensions of an Aerovee vs. the Aeromomentum it looks pretty close. The weight of the Aeromomentum is less including fluids. I go to Sun N Fun most years and plan on visiting them and other vendors for ideas.

18"W x 22"H x 23" L - Aeromomentum AM10 - 75 HP

30"W x 20 - 21.875 "H (optional air cleaner) x 24.25" L - AeroVee 75 HP

Reached out to the Aeromomentum folks regarding the 75 HP engine.

It can be canted to about 20 degrees.  We are not planing on offering a greatly slanted (70 degrees) version at this time.  We are using a large offset gearbox so that the prop is about 9" higher than the crank centerline.  The total engine height is about the same as the AeroVee an other VW conversions.

Among the other issues converting auto engines to power aircraft is the lack of proper Propshaft and propshaft bearing. While this can be diminished by  installing a propshaft tower with a long plain propeller shaft bearing, the problem has been reduced not eliminated.

I have had other issues with the Jabiru engines I installed on my SII LS, but they have been manageable so far. A broken crankshaft is pretty close to disaster.

Not to rain on a new engine parade or dissuade economy of scale arguments, however....
I’m not convinced water cooled 2-stroke engines add reliability and longevity or are a viable alternative aircraft power plant.

Having flown a Rotax 582 powered EXP for several years I can assure you periodic maintenance is an understatement as is simplicity when it comes to liquid cooling. If you’re going the liquid cooling route, why not buy a used Rotax 912S. Same weight as a Aerovee and is a certified aero engine with 100HP.

   The blueprinted GP1835 I installed in 994SP is one of the most reliable and smooth aircraft engines (besides jet engines) I have flown. For economy of scale and simplicity, not to mention installed weight, a well built VW is hard to beat. Even the venerable Continental A65 pales in comparison in price and installed weight.
