Looking at .15 engines there are quite a few choices. Also my next question is how do these engines compare to the much older fox .15 I used around 1978-1980. There is the enya .15, fox15 and magnum 15 I think. Are these all set-up as control line as they come and how do they compare ?

Enya has their 15 and 20 (and up to 61) in CL setup motors from the factory, they work well, The Magnums are RC motors that will need converting

Randy can you give me an idea of how the enya's compare to the older fox .15's

if your asking about the older plain bearing ones the Enya is stronger and will last longer, If your asking about the bb Fox 15 newer version the Fox is stronger. The Enya is a nice 15 stunt engine, and they also have several 15s to choose from

Jim, you might want to look at an ASP .15 http://justengines.co.uk I bench ran one last week with a 8x5 prop just under 13k rpm. (only had 1hrs running in time) According to the Aeromodeller prop/power chart (April '94) that's about .30 bhp.
I think the old Fox .15s were doing around .23 bhp

I'm going with the Magnum .15XLS for my needs in this size power. 16K on an 8X4 MAS scimitar and it's not yet broken in.
-
I thought the magnum had the same problem as the AP engines that they have carbs on them ?
-
A few minutes with a lathe and a drill press, .10 worth of delron rod, and it's all fixed.
-
So what needle valve ? andd diameter. How would you say it compares to an enya ? and weight ?
-
I modify the RC needle valve from the carb to be used as a post style needle valve. I like this setup because it allows the fuel line a straight shot to the assy, and puts the adjustment opposite the muffler when mounted inverted. I use the same diameter as the carb, but forget exactly what that was right now.
I cant compare to an Enya as I don't have one. The weight without muffler is ~6 oz's.
-
Could you post a picture of what your venture and needle valve mod look like ?
-
Made in Japan Enya .15 from Randy, $70.00 ready to go.
Made in China Magnum .15 from Hobby People, $62.99 needing (as a minimum) venturi and needle valve mods.
I know what I would choose... 8)

That's why I'm leaning towards the enya. Only real differences . would be if the magnum is a ball bearing engine with more power. But I'm looking for a plug in and fly version. No needing to swap venturi's or needle valve. I plan to order by the 5th of sept. waiting for next pay check for me. I do not have a lathe or at this time a drill press.
-
Well Jim Though the Magnum is a nice dual BB engine, you would have to get a venturii and set it up. The Enyas are excellent engines, and do come ready to drop in,
-
The Enya 20 is a great little engine Also, many OTS flyers use them in OTS smaller planes

How about the OS Max LA 15. I have three of these but have not run them yet? The Enya 15 is an awesome engine. You can't go wrong with an Enya of any size. IMHO..

Also consider the MVVS 2.5CC, these are still available with CL venturi in diesel and glow, the cylinder is rotatable for either side or rear exhaust configuration, cost is around 55-75 EU Link (http://mvvs.nl/)
