46. It'll give a bit more grunt for when you start doing aeros and you can always throttle back.

[Eamonn Fahey]

+1 on the 46 and throttling back.

Would the OS .46 LA [ Blue] be OK

Hi Colin, any OS engine is an exellent choice, but be prepared to pay a bit more for it. I must also say you would not go far wrong with an SC too. The LA has the needle valve at the rear of the engine, so it is safer for beginners and old hands alike. Cheers  just checked Boomerang spec.  40-46 2stroke.Both will fly it, its your choice.The SC46 will be ideal, as said before ,you can always throttle back.  Cheers

Thanks all for your help.

I agree the SC46. I recently got a SC52 for a Seamaster I am refurbishing. The SC came with the rear needle components too.

Another vote for the SC .46.

Great little engines, good value and reliable

We have a novice flying a Boomerang with SC 46 in the club. perfect combination.

SC engines are great, I have at least 15 at the moment and have had lots more. Much better than an OS LA.

Another vote for the 46.....you can always throttle back....

I personally wouldn't go for the 46LA they're hardly power houses as they're plain bearing (IE the front of the crankshaft is supported by a brass block with a hole in for the crank). This induces more drag that an engine with a front ball bearing (like the SC46). The LA series are not bad engines but they're not exactly cheap, they won't exactly rip the firewall of your engine and when the plain bearing wears out it's new engine time. At least with a SC46 you can change the bearing quite simply. I'm afraid my love of OS engines was also tempered by the problems they had with peeling liner coatings. No point paying more for a "quality" engine and then it failing on you.

Hi ColinJ , my vote goes for the OS 46 any...it's :lighter,more durable,stronger and of course little bit expensive.

good luck

Jo.

Hi colin,

Don't want to confuse but have you considered the ASP 46 - £57 from JE?

Very similar to SC.

The ASP 40 I have runs better than my OS46AX.

[ColinJ]

Richard. Who is JE.

Cheers

[Richard Wood]

Just Engines Colin.

Take a look at their own .47 as well.

[ColinJ]

Thanks Richard.

[Peter Miller]

You might consider that an SC 40 will have nearly as much ower as the OS 46 LA. A little cheaper and just as good for what you want.

[David Hodgson]

If you intend to start your engine using an electric starter then I would avoid the OS LA series.

Why is that David ? Ive got a 3 year old 46LA that gets started plenty of times with an electric starter and its fine

[andy watson]

I'm still running the OS46LA that was in my trainer. It's moved into assorted 40 sized hacks and performed perfectly throughout.

To be honest, the OP will be fine with any of the 46 sized engines he has mentioned- you are pretty much into the area of personal taste/preferences.

Just my experience of running plain bearing motors and finding they wear faster when started this way.

Also found that as the bearing wears the crankshaft can be forced in to the back plate.

All that said I start my lads 40LA by hand and can do it faster than than it takes to get hold of the starter.

There should be a blue steel washer behind the prop driver to prevent that happening David.....without that then yes the front casing will get chewed up.....
