Default Three New Alternative Engines
Taken from a recent OSHKOSH video. I personally know Mark Kettering, the owner of Aeromomentum engines and he does SUPERB work.

The cousin and I were talking all week about the AeroMomentum engine. Can you imagine one of those turbo 260hp's in a -10?

Wow. When they have a firewall forward kit ready for a -7 or -8 or -10 I'm in......

Has anybody taken delivery of one of their motors?

Be sure and research well before you purchase..... An honest aircraft motor has never been replaced by a conversion with any success. Make sure you are willing to spend the money and time needed.

............"never say never".............

Amen to that. I have taken more auto conversions out to install Lycomings than I care to remember. On the other hand, an auto conversion plane can be had for a bargain, cheap enough to put a Lycoming on and be money ahead.

I have spoken with several owners with flying conversions that work just fine. That is not to say, by any means, that the conversions are the way to go for the majority of folks. The additional time, effort, and expense to get them working is substantial.

I truly admire the people attempting to break the mold and move us into the future...getting away from the 60 year old technology that is the current norm. Those are the folks that will push progress forward, rather than remains stagnant with the status quo...

THEY put the experiment in experimental...

The first part is good advice but "Never" is a pretty strong word...

Let's see:

Russell Sherwood's Subaru EG33 Glasair, multiple SARL wins. Routinely destroys Lyconental powered aircraft having 50-100% more displacement. 700+ hours later, still working fine.

Gordon Wardstrom's Bearhawk with Rover V8 power, 1500 hours, never touched.

Gary Spencer's LongEze with Ford V8 power, multiple race wins, 1000+ hours.

Jeff Ackland's LS powered P-85, cheaper, faster, lighter and lower fuel burn than the M-14P powered Radial Rocket. No problems to date.

PA-25 in Australia used as glider tug. LS V8 replaced the Lycoming 540 engines which were not lasting well. Huge reduction in operating costs per flight hour with considerably higher tow performance.

Bjorn Anders Subaru EZ30 turbo powered RV-7, over 600 trouble free hours to date.

I could go on.

For sure, not for everyone. Lots don't work out. Lot's do.

"Never" simply isn't accurate.
