24K gold plated motor casing, 100 + N thrust ( mine is slightly de-rated to run at 45°c reliably ), improved bearing cooling, new compressor design etc...

This engine is an absolute beast. I had to change the standard mounting tab that I use for the normal M90 because the engine was sheering then.
I've never seen so much power from such a small engine.

Gaspar, you're an engine magician .

Will post a video of the test runs tonight. Stay tuned...

By the way, this one came as the new kero start version. However it retains the glow plug in order to be converted to gas start on the field in case of a plug failure...

100+ N = how many pounds thrust?

100N = 22.4#

Esprit

A Newton is the SI unit of force.

It is defined as the force required to accelerate a mass of 1kg at 1 m/s/s.

So in simple terms 100N equates to 10kg of thrust which in imperial terms is ABOUT 22lbs

Hope that helps.

25= lbs ?

For those of us that are math challenged [:@], google "newton to pounds" enter 100 and bingo 22.4 pounds.

AndyAndrews

Thats what I got from the conversion - not exactly "mount ripping" thrust. So I was a little confused. I guess verses the M90 its much more thrust? I don't know anything about the Merlins.

Maybe it is the "+" that does it.

Anyway, good looking turbine

Yeah, that's a real animal! Same thrust as a P80SE.

Andy,
The Merlin90/110 is so small that it has to be mounted with plywood mounts to fasten the engine in the SuperPhoenix. In order to get the thrust line located correctly for hovering capability, the mounts shall not be thicker than 1,5 mm. Plywood mounts were fine with the M90.
I had to abort the first engine test because the 110 was cracking them. I replaced the mounts with carbon plates:



Here is the 110 with the carbon mounts.

olnico

Yes that is exactly it .
I got 105 N on my bench at 37°c/99°F this afternoon ( QNH 999 hPa ).

That would certainly make it push 110N in ISA conditions.

olnico

I get 95N from my P-80SE at 100°F/1000 hPa ( check the lastest RCJI article )
The 110 gives me 105N in the same conditions.
The thrust difference is very noticeable on the SuperPhoenix on the ground tests ( flight test tomorrow ).

Also look at the size difference.



Additionally the P-80SE is pushing 97N at ISA for a weight of 1,491 kg. That is a thrust to weight ratio of 65 N/kg
The Merlin 110 is pushing 110N at ISA for a weight of 1,050 kg. That is a thrust to weight ratio of 105 N/kg. Nearly double the value of the P-80SE.
The difference in efficiency is stunning given the size of the Merlin.

The best efficiency that can be achieved in the P-80SE diameter class is of course made by the P-160SX. For comparison purposes the latter is giving 103N/kg...

Don't be mistaken, I love my P-80SE. It is a fantastic smooth and powerful engine. It runs very cool and will certainly last forever.
If I'd have to compare the two engines with cars, I'd say that the P-80SE is a BMW M5 and the Merlin 110 a Caterham R500...

Look at the attention to details on this engine:



Gold plated inlet venturi, black anodized compressor. This engine is a jewel in itself and runs quite amazingly well.

Also note that the external plug lead has been removed, but the plug itself is still here for an easy conversion ( the lead is folded inside the inlet cowling and can be extended in a matter of minutes )



I also love the iridescence of the gold plating at the exhaust:

Hello:

Congratulations for your new engine. Enjoy it.

Carlos.

Thank you, I will .
The SuperPhoenix and M110 Gold Edition will be on demonstration at the Jet Power 2009...

cool engine , what does the gold plating do ? is it related to heat dissipation .... or is it like fuzzy dice ?

Gaspar

Just to give the credit to who deserve it, the look of the engine is a creation of my friend Jesus Bardolet, www.bardolet.net, I'm only responsible of the hidden parts.

Wow! Now I get the picture. Awsome! Let us know how she holds up.

Links to Merlin?

Do the Decimal Points Count?

Actually there are only 9.80665 Newtons in I KgForce and there are 2.2046lbs in a Kilo.

Hence if that engine is putting out 110Newtons at standard pressure and temp - it equates to 24.74lbs - NOT 22.4Lbs.

In practical terms, I recently changed from a Jetcat P80 to a Merlin 90 in an Elan (Boomerang). Even after removing 110grms from the nose it was still desperately nose heavy. Had to change the ECU battery in the nose to halve its wieght and move it back, to re-balance the model in flight. In the air, 3/4 throttle on the Merlin = full throttle on the Jetcat for the same speed. I presume the reduction in weight = lower drag. I found I could increase my flight time alarm for same fuel tank from 7 mins to 8.5minutes to finish with the same reserve on landing.

I suspect if this new engine is installed in a model such as a Classic Bandit, which already has a low drag profile and air ram/or supercharge effect from the air-ducting, then I would expect the performance to be startling in both speed and endurance. It would also be kinder to the undercarriage with a lower weight and landing speed.
