I believe that the availability and the fun of small engines need to be communicated better and such engines would find more acceptance. Electric flight does not offer the same fun as do these engines and when I got into the hobby 30 years ago, both options were readily available. I found engines more interesting, but I also played a lot with electric motors.
today, most ppl do not know that such engines even exist, but I am confident that there are many fellows out there who would enjoy playing with these little machines.
On the other hand, I believe that methanol engines are still a valid option in the smaller sizes. I agree that it is more economical to use gas beginning at engine sizes of around 0.61, but below, the methanol engines, or nitro, as most ppl call it, can't be beaten.

AMEN to that! Pipek since you're in the great white north how do the methanol engines do in the cold weather, do you need to let them warm a bit before flying? Compared to you guys in Yellowknife we don't know what realy winter is in Oklahoma.

The winter weather can be pretty challenging. Winter is in fact the best season for RC stuff. We do not have any flying fields here. Canadian shield, bush and more rocks and bush in the summer...and I am not so much in the float plane business. Winter means access to vast flat areas and thanks to the ice roads these areas are easily accessible. We maybe enjoy the longest runway in the world here. :-)
Winter flying is pretty tough though, but I still go out down to -22F. It does not take long and servos freeze, displays freeze. One good thing is that electric motors can be overpowered since overheating is not an issue.
I have not run methanol engines below 0F, but I will take my new Enyas to the test next winter.

Pipek- We saw your hand holding the model and nobody was fooling into thinking it was really flying. Next time, the wings make it look realistic.

I put the Quicky 09 on the test bench. The following numbers have been obtained, thrust in Newton (N):

APC 7x6; full throttle; 11200 RPM; 4.1N (short exhaust)
APC 7x6; half throttle; 7800 RPM; 1.8N (short exhaust)

APC 8x6; full throttle; 8350 RPM; 4.2N (short exhaust)
APC 8x6; half throttle; 6500 RPM; 2.4N (short exhaust)

aero-naut 9x6 Profi Prop; full throttle; 7100 RPM; 4.2N (short exhaust)
aero-naut 9x6 Profi Prop; half throttle; 4200 RPM; 2.2N (short exhaust)

I also tested an aero-naut 9x7 Profi Prop. 6000 RPM and 3.2N indicate that this prop is to big for the engine.

I do not use an electric starter. Starting an engine is much easier with larger props. Larger props also increase idle running stability. While the APC 8x6 is already a good fit for the engine, the Profi Prop 9x6 reduces sound levels further. Both the 8x6 and the 9x6 deliver adequate power and they take advantage of the available torque.

Smaller props should not be used due to high RPMs with excessive noise emissions for no gain in prop performance.
I also tested the larger exhaust that provides better noise reduction than the standard silencer. for the APC 8x6 a RPM drop of 100 only could be observed. I highly recommend the larger exhaust due to the significant noise reduction especially in the high frequency band.

I used 5% nitro fuel from a brand called "Morgan Fuel". I cannot recommend fuel from this company. The fuel does not offer any corrosion protection.

I am already looking forward to putzing around on the 9x6, half throttle, nice engine sound and duration flight performance.

Any one know which Enya engines share the same needle valve as a 46 4C? In photos, most Enya needle valves appear to be the same.

For instance, this one looks exactly like a 46 4C needle:

Mr Cox

That's what the diesel engines excel at!

The props you are using are simply too large for the glow .09 engine, the power peak is up at around 14-15000rpm. I'm using a 7x4 -7x5 prop on the .09 glow engine, depending on the plane.

For the diesel engine (.11CX D) they are absolutely right though, and with the quiet-muffler you'll get a very soft exhaust note too. Beats many of the electric motors actually...

He shows the Enya stock number is 09230F, I show the Enya .46 4C should be Enya stock number 464C40F1. I would say it isn't a match. You could try emailing Enya in Japan and see if they will sell you one and mail it to you. They show it to be about 420 Yen (about $4.00) Their email is

I have a pile of Enya engines now too... Golly if I can remember them all...

(4) .15-IV (two were used, two were NIB, only one is NIB still)
SS30bb iron/steel (my favorite engine - the sweetest of the bunch!!! Got NIB)
SS35bb Heli ringed (needs bearings and hone job)
SS40 (low timer, not run yet)
.45 twin ring model 6001 (disassembled - needs new crankcase possibly)
.40CX (not run yet, looks like a low timer)
46-4C Mk I
60-4C
R120-4C

There might be more, but I can't recall off hand. I need to finish refurbishing the 40CX so it and the SS40 can be test run, then I'll rebuild the SS35 Heli engine. The bearings are shot from sitting and the ring isn't seating.

I have a brand new in the Box Enya 4 stroke 120 R. I may put it up for sale.

I have a NIB .46 4C earmarked to go in a 48" Zeppelin-Dornier D.1 and would love to expand my 4C Enya stable if my wallet would allow it. I love the craftsmanship and the way the Enyas are built. The carbs aren't as pretty as an O.S. or a Saito but they are good workhorses and that is all that is important. I look for reliability and ease of use so you will probably never see a YS in my collection.

That's too bad about probably never having a YS in your collections, because rumours about them being undependable or needIng a lot of extra maintenance is one of the biggest myths in R/C.
I love Enya's. Ive had a bunch of them & still do.
The fact is is that YS makes engines much as Enya does- a lot of assembly, fitting & checking by hand, and VERY high quality mettalurgy.
The reason folks believe these fairy tales about YS engines is they dont educate themselves on them 1st,& what they need to know is easily available via the U.S. warranty Dept on their web site.
YS'S have a diaphram and a couple o- rings that's less than 20 bucks total, they should be replaced annually, or anytime a YS that was running good isnt..A 20 min job, tops. They run as sweet at low & medium speeds as top end.
Enya's, much as I love them, have had their problems too. Like the 4strokes & their annoying air leak.
That's an easy fix too though.
Try a YS sometime, a new one so you dont get one someone couldn't figure out then jacked it up.
I'll bet you like it .

Not a myth at all and people who don't find them user friendly are not idiots.

Hey, who called anyone an idiot ?
Let's hear Details on YOUR experience with a YS engine then ? Oh, probably just seeing someone struggling with one ?
An idiot is one who spread BS and is too proud to admit he doesnt know what he's doing with a product yet still bad months it.
For anyone who wants to know Mike McCormick, Don Ramsey& friends have a YS "Bible" easily Googled that's great reading.
WILL save gnashing of the teeth if followed, these engines are flat out different than others. Stuff commonly done with other motors you dont do with them.
But of course you must know all of this, but someone else may be able to use it.

I owned four of them at one time all FZ's, ran 20/20 fuel in them, did everything right, about 90 days reliable running was all you could expect. Never again.

1QwkSport2.5r

I have zero interest in YS, I don't care for the more complicated fuel system. I'm not an idiot, just don't want to deal with it. As for Enya - I have lots of them including several 4-strokes. I'd like to know about this air leak that was spoken of. None of mine leak air - they run like clockwork every time. Not exactly a powerhouse engine, but when reliability is important, I turn to Enya. With some changes, they can be very powerful.
