Evolution 36 Control line engine

[Mike Greb]

Another engine. The last thing I need is another engine. The more I hear about this one, the more I want one. This one won't drop into any model I have. The Tutor II would have been a good choice, but that one is gone. What ARF would be a good match for this one?

I have a Evolution 36 that I have converted from a RC motor by machining a venturi for it.   My motor is a real nice match for my Cardinal ARF.  I made my venturi out of aluminum.  When I tried to make a derlin venturi the drawbar would crush the throat of the venturi and it would fall out.  No problem with metal.

[Dave Adamisin]

Dave,
I bought an RC version from my LHS for 40 bucks, never been run. Any idea when the venturi's will be listed on the parts list? I think a FP tounge will fit this bolt-on size..I was going to make a delrin venturi for it, but I like the looks of the blue anodyzed one shown here.BTW...did you count how many head shims come on the CL version?The RC version seems to have really high compression, so I had my LHS order me some extras..

And to think there were some naysayers saying it couldn't/shouldn't be done with this engine when I considered modifying it! Ha!!
 

There were 2 0.004" (.1mm) soft aluminum shims in all the engines I worked on. You have to ask Pete about the parts.

[Richard Grogan]

Thanks Mike and Dave! Metal is is. I will try and get ahold of Pete and see if he can get me a set.

 Or Mike, you can make me one and bring it to the Roundup next month?? lol

I measured the Magnum 36XLS which I set up for stunt and used for several years in an ARF Nobler. 
I added the weight of the remote needle valve assembly, as that is used on the Evo.

                              Mtg.            Mtg.        Mtg.    Thrust
                             Hole    Case   Holes     Holes   Washer   Overall Overall  Bare weight
Mfg   Model     Disp.   Dia.   Width  Fore/Aft  Width  Frt Hole   Width   Length       oz.

Evolution 36    0.36    0.13    1.18    0.59      1.49      1.85      1.77      3.00       9.3
Magnum 36     0.36    -----    1.197   0.59      1.50     1.74      1.776     ----        8.9

So, the major difference is the mounting distance to the thrust washer face (0.11 in) and the weight 0.4 oz.

Don't do ARF's but seen 'em all, flown some of 'em so here goes:
Clearly: Nobler, Smoothie, P-40, Vector 40, Sig Primary Force, Oriental
*Argueably: Cardinal, Pathfinder

*Fine IMHO, opinions may differ 

Did I miss any?

Tutor II

[Balsa Butcher]

Actually I didn't forget, just think the Evolution .36 may be a bit small for the Tutor II so I didn't mention it.  It is advertised for a 40-51 and around here, an LA-46 seems to be the engine of choice.  As many know, the Tutor II is much larger than the original Top Flite Tutor. That one would fly well with an engine as small as a Veco 19.  And yes, I joined the crowd and have an EVO on order as well 

[Garf]

I have an original kit for the original Tutor. That might be a good match.

[Steve Scott]

Horizon must have noticed an uptick in sales for CL engines, presumably at Tower, good sign.

Sounds like Pete Bergstrom has been pretty successful introducing new CL versions of Saito's and Evolutions at Horizon.

[Arch Adamisin]

Some more information.
Pete was able to stay over an extra day following the Toledo show and we took him flying. We flew two different Evos with different mufflers and venturis. One was In an ARF Vector and the other in an ARF Cardinal. We used 11x4, 11x5, and 11x6 props running on both 5% and 7.5% Cool Power fuel. The motors ran effortlessly  are were more than enough power for either model. We flew lap times varying from 5.2 to 6.4 seconds during the numerous flights and we had no issues what so ever. The engines ran 6 minutes on 4 ounces of fuel. All the props were off the shelf items, APC and Power points. We didn't use any custom pieces at all.
Both mufflers worked great and the tongue muffler was much more quiet than I expected. The tube muffler has a really nice sound, and would be the one I'd use because it sounds so good.
I'd just thought I'd let you know, they really do run nicely.

I am looking to by a ARF Oriental from Larry Renger, is this engine enough to power it?  I had planned to put in a new in the box Brodak 40, but it's boxed up for a move I will be making and I don't which box it's in.  (great excuse to buy a new engine )  Is this engine a good substitute for the B-40?

I have an L&J Fox 35 in my ARF Oriental and it does great. I see no reason the Evo 36 shouldn't be fine also.

Hi Andrew. We've been flying a Cardinal Profile ARF as well as a Brodak Vector arf with plenty of power. I think that the Evo 36 would be a great fit for the Oriental as well.

[Andrew Borgogna]

Thanks guys, you talked me into it.

[Steve Holt]

Andy,
Be careful about the CG on the ARF Oriental with a heavy engine.  Even with a Fox 35, the ARF seems to assemble a bit nose heavy.  Mine had a Magnum 36 in it and it needed about 2 1/2 oz tail weight to get the CG correct.  The Magnum was as far back as the firewall would permit.  The ARF Smoothie, on the other hand, tends to assemble tail heavy with a light engine.  The Magnum with a light tube muffler and plastic spinner put the Smoothie CG right on.

Where are these engines' made?

Anybody know the ulitmate source?

The ad says "available May 08".   

As mentioned above, $80 for on engine with three venturis, an NVA, and good muffler is give-away.

Paul,

Of course they are made in China, People's Republic of...

The info is on the Evolution Engines website, at the address in small print on the bottom of the inside front cover, June 2008 Flying Models. Maybe Horizon is serious about these? That's a full page, full color ad...

Checked further on the site and found that many of their Evolution and Saito engines are on back order or expected in late May or so. (Note: Saito has a small-medium - for 4-cycles - CL version for around $150... Small, light - for 4-cycles - and quite nice RPM on prop numbers.) The descriptive comments seem to change from one page to another, but compared to some of the early Owners' Manuals/ Instruction sheets from that side of the Pacific, years back, at least these look quite close to well-written USA English as we're used to it.

The EVO engines site allows downloading of the manuals as .pdf. The 36CL manual isn't up yet, but the engine looks quite similar to their 36NT RC engine, probably will have a similar manual. Glad to hear the bore/stroke numbers come with the revised timing and porting.

Thanks, yet again, Pete B!

[Andrew Borgogna]

Well I got all excited and went to Horizon and placed an order for the Evo .36 only to find out I won't get the engine until June.  I guess the good news is somebody is buying these engines.  I would like to see some other input regarding break in and use but I am committed to using one.  I plan to break it in like I did the B-40 I have and use the GMA blend unless I hear otherwise.
