Motorav engine

[Pete]

I see there is an interesting engine in the 100hp bracket that was exhibited at Sun n Fun
Based on the VeeDub layout. The company doing it seems to be fairly substantial.

It's going to take a lot to dethrone the well known leaders of the pack....

Very true Flooi. Revmaster is probably the oldest, been around since 1960 ties .

Been around for a long time. Will be interesting to see if they actually do get a product to market.

The big advantage of this one is that they did not try to maintain VW compatibility. Everything is redesigned for aviation use. Nice big #4 bearing cast in. Single piece crank. Bottom exhaust and intake ports. Basically addressed many of the weaknesses of the VW as an aero engine.

Could be interesting in seeing it head to head with the new Revmaster R3000 (also completely redesigned).

If you read the background (VW) it sound impressive. But when you look at the specs in terms of TBO, requirement of 100 octane fuel and consumption ( 22-30 Liter /Hour at 100 horses), King Rotax does not need to be concerned at all. Looks like the hired Lycoming consultant was too much looking north instead of the places that really fly LSA and where avgas is hard to get or expensive like hell.

Yeah. AVGAS could be an issue. Should be possible to release a low compression version, which would produce around 95hp on 93 octane fuel.

TBO is always low on first release (see Rotax 915 which also has 1200hour TBO), and will likely increase as fleet hours are built up. Fuel consumption pretty much identical to 100hp Rotax.

Could be a very good option, at the right price.

The right price.... Revmaster has their R2300 turbo engine at $500 less and at 105hp, even at high above sea level, and is rated to run on both Mogas and Avgas, or a mixture of the two.
The Revmaster even weighs less with all it`s accessories , the Motorav still needs an oil cooler, exhaust ,and intake filter plus alternate air source with filter. Add that to the engine`s weight,......and see where the weight is at then.
Not knocking it, just saying......
