Ed, where is your appreciation for the finer things in life. A Saito wins hands down if only based on the beauty of their function, same for the Enya.

You know that I agree with you, Dave. I was just pulling on some folks strings. No one took the bait. <G>

If you want a Saito and Enya comparison.

I have the Enya and a Saito .62.

They both spin the same size props at near enough to the same rpm's although the enya is rated a 1/2hp more than the saito.

The Saito .62 is a full oz lighter when both engines have their respective pipe fitted.

My saito is a sweet little motor that starts easily and runs like clockwork. I haven't tried the enya yet and i'm itching to see how it goes. I expect there will be some differences in the way that the power is delivered. I'm looking forward to flying the enya on the same model as the saito for comparison.

Any updates on the 61cx?

Funny you should ask as only just this minute i have came inside out of the shed after spending a few hours making a test stand ready for the break-in.

Curiousity got the better of me so i put the enya on the stand and started it for the first time.

I couldn't run it for too long because it was 9:00pm at night and the neighbours would complain, but with the needles set to the recommended break-in settings it started straight away using my electric starter and ran pretty smoothly for the 3 minutes i ran it, just enough to get up to operating temp.

The fuel i used is 15% nitro, 15% klotz KL200, 5% castor and 65% methanol.

Weather permitting, i'll be running it properly this weekend and hope to have some initial rpm figures.

Why???

This is a break-in - not a pylon race...

Even four-strokes from Enya run well on 5% nitro.

Here's an initial report on the first break in runs of the CL version.

DarZeelon,

I shouldn't have to justify how i choose to run my motor, but i will anyway.

The fuel i used is an off-the-shelf 1 litre bottle that i picked up at the store because it was the only one on the shelf that had some castor in it. I normally pre-mix my heli and 4-stroke fuels at 20% nitro and 20% synth but up until now have avoided castor.

The enya is ABN so castor is recommended and the store didn't have castor separately.

They usually have the same brand of fuel with 10% nitro but they were out of stock so i went with the 15%.

When i've used up this 1 litre bottle (3 tanks) and i've sourced some castor i plan on adding 120ml castor and 880ml methanol to 3 litres of my existing 20/20% coolpower blend which will give me 15% nitro and 18% total oil with 3% castor.

CustomPC,

You don't have to justify anything to please me

, or anyone else...

For all I care, you can throw this engine off the Sydney Harbour Bridge, to see if Ken Enya made it so light that it can float...

...It is the fact that Enya does not, as far as I remember, recommend the use of that much nitro in their two-stroke engines.
And... to break-in a non-ring engine (and also for its general running), more than 5% castor oil should be used.

Sometimes it is better to delay a procedure, like break-in, until you have the right fuel for it.

Times must be changing as the manual recommends from 5 - 15% nitro, and Mr Enya himself quoted 15% when i asked him for some performance stats.

This is also an ABN motor. The liner is coated with a nickel/silicon carbide composite, which i believe is another first for Enya, and i agree that more castor is probably a good thing but i hate the stuff and it took a bit of soul searching for this clean-freak to start using it.

downunder, have you done similar documentation for your 60 IIIB? I am very interested in hearing what prop it likes, etc.

---------------

Your Saito .62 won't begin to come close to an Enya .45 CX, much less the .61 CX, if both engines are put on a dynamometer and set up to produce gross horsepower, regardless of rpm. I understand your pride in your Saito .62. I'm proud of my Saito engines too, but four-strokes don't produce the same amount of power as equivalently displaced hot two-strokes. Even YS is challenged to keep up with a good two-stroke of the same displacement. I don't want to see myths starting up all over again about this topic. It simply isn't true.

I'm a Saito fan with lots of singles and two radials, but let's be real about this.

Four-strokes can tolerate a bit more load for their displacement without going into preignition. The two-stroke is challenged to do so because the residual charge from the previous combustion cycle contaminates the fresh fuel charge and lowers the octane rating to the point that any additional load over standard causes preignition. Add enough head gaskets so that the two-stroke doesn't go into preignition and be amazed at the whooping it will put on the four-stroke with even larger props.

Now, since I have admittedly gone to mostly four-strokes, I understand why people tend to favor them, so you won't get any argument from me in that regard. Power isn't everything. <G>

CustomPC,

I have seen older manuals and wasn't aware they now warrant more nitro... They must be 'Americanizing'... Maybe MVVS should also do that to increase sales...

As to castor oil; one of the good points for many in this hobby is the smell of castor residue

.

"I love the smell of castor/napalm in the morning."...

I am sure there are now several people frowning at your post

.

As to this engine being ABN.... NIKASIL is a composite deposited on porous aluminium bores in many Mercedes-Benz, Rotax and BMW (Zachs) engines...

In the model industry, I believe YS uses it on their four-stroke ringed engines. It used to be on brass bores (which cannot be real NIKASIL), but is now on aluminium.

OS used to label their ABN engines as ABC, but their's was just nickel - not a composite.

I do hope Enya is not taking that route...

Ed, i whole heartedly agree with what you say about 4-strokes.

I wanted to make the comparison between the Enya and Saito because this Enya is not your normal .61 2-Stroke. Being a bored out .40 it's more of a Torquer than a revver.

All of the rpm figures i've seen with the same sizes of props are very close to each other but i'm sure that the motors deliver that power differently.

4-strokes are renowned for their quick throttle response and low down grunt.
On the other hand, Enya's TN carb and CX motors are also renowned for their throttling.

The Saito .62 is a sweet little motor and produces more power than we expect from a .60 4-stroke. Saito's policy of squeezing more cubic inches into the smaller case sizes has turned out a real winner with the .62.

But, I'm sure that the Enya will trump the Saito in the end.
I intend to keep both and will fly whatever tickles my fancy on the day.

The specs on the manual page for my motor say brass sleeve plated with Nickel Silicon Carbide composite. I have no idea what silicon carbide is or if this is a new plating method. Perhaps someone could enlighten us.
