Aeromomentum RV-12

[poormansairforce]

The Aeromomentum based FWF for the RV-12 will be a game changer; a prediction.

I hope your right because I'm sure looking at them!

So far it does look good. I'd like to see more people flying behind them before I'd feel comfortable buying one though.

Been around for a while now in airboats as well, I know Mark has changed an engine core (Suzuki), but retained the PSRU, at 4000 hours on one (airboat).

That's impressive!

That is impressive. PSRU longevity is usually the bigger challenge.

4000 on an airboat! How much flotsam and jetsam have gone through the prop? Aren't these things supposed to eat debris?

I can’t seem to find any reports on Aeromomentum fwf from actual end users. It sounds like a great option, but would like to have a report from someone who has flown behind one.

There's an Aeromomentum Owners' group on Facebook that you can request to join. That's where I'd start

Non- Biased Engine Reviews -Aeromomentum

Lot of people talking about Aeromomentum. Any real life reports from pilots flying those Suzuki's? Any numbers on how many are flying? Any idea how many have been sold?

In the design of my aircraft, I originally looked at the 912ULS, then looked at a BMW R1200GS conversion, then a Yamaha Apex before I stumbled upon the AM-15. Price point and performance right on par. This said, it was not until a few days back that I finally got to fly an RV equipped with the same engine. I am very impressed. Engine performance was crisp and predictable, and very hassle-free. This particular engine I flew has close to 850 TT on it, and the owner has reported ZERO issues. Having a good amount of GM/Suzuki auto engine experience over the years, maintenance looks to be straightforward; the PSRU is solid; the owner said again, no issues...or leaks for that matter.

I'll be doing another flight this weekend up to my design cruise altitude to get a feel for it in that environment, but so far, so good! Cannot wait to get my hands on one.

I have been looking at an AM-10 (85hp) for a project in working on. I cannot find any info on the sales of those engines. I have sent out email from the areomomentum contact link and have not recieved a reply. Do you have a link with any info?

Their website says they are not taking orders for this engine.

If you need an engine in this size range, perhaps the Raven people can help you out with one of their smaller 3 cylinder Suzuki conversion, or Rotax Rick will sell you one of his liquid cooled two strokes.

The AM-10 is currently vaporware. Not taking orders and no flying engines. The Viking 90 is real and flying, and the Yamaha might also be a good option.

Thanks Todd:
I have been looking for 4 stroke engines that are close to the 100lb. mark. I did look at the Viking. Nice engine

Jeron at Raven has been out of the business for a few years now as far as I know.

Laverne,
Here's a very recent post from Mark Kettering with information about the AM10.
Not so complicated but proven conversion?

About 'avionized car engines', serious doubts were in an article I already sent: 'Power struggle: why car engines won' t fly', by Don Sherman, Air&Space, Dec 1996, Jan 1997; pages 71-81.
For low cost engines, besides Wankel, you can consult 'AeroExpo'

Using nearly 20+ year old articles? Just stop that. Stop that right now. The motors available to today are nothing like what they would have used in the 80s/90s.

Cooling is all but figured out. PSRU's are highly refined, ECUs are miles ahead of what they had back then.

There are at least two sucessful car motors in 'production' for E/ABs. Not to mention the numerous LS1 conversions and corvairs.

There is nothing stopping a car motor from running 100% power for hundreds of hours. They do it almost every week at Toyota as part of QC.

Toyota puts the pedal-to-the-metal when testing engines

Toyota randomly selects completed engines and subjects them to 180 hours of full-throttle operation. This test is equivalent to driving a vehicle at maximum speed for 7.5 days-non-stop. The test checks the strength and durability of parts like the crankshaft, bearings, connecting rods, pistons, valves and camshafts. If the engine can survive 180 hours of high-rpm abuse, then years of commuting will seem like a walk in the park.

For certification, an 'aviation' engine only has to go 150 hours. Read the AC for engine certification.

You can rebuild a car motor at the 500, 750, 1000 hour mark. The only reason aviation engines are TBO at 2000 hours is becuase the maint manual suggests it. But how many engines make TBO without a new jug? Or needed mags overhauled? Funny, replacing a jug doens't phase airplane owners even though its a $2k expense. I can rebuild a car motor for less than a grand, and have a 'new' spec engine for what you are paying to rehab one jug after 200-500 hours.
