If anyone cares ... after months of neglect, I finally got my evolution 46 to run correctly. I found a pin ***** hole in the fuel line and tightned the stopper in the fuel tank and magic ... nice, strong, smooth operation again.

I'm putting floats on my Alpha and going boating ... sort'a ...

Cheers!

I also have a Hangar 9 alpha , and I have been contemplating on adding floats. But I do not have a clue on how to begin. I would appreciate any and all info.

11X6 Zinger, I left the flywheel on, and I have lost count of the number of flights. Last two flights were in an extreme downpour.
Still starts and runs very well. I grab the spinner, and just give it a quick twist backward against the compression. No fingers in the prop.

Okay, I went to my LHS yesterday to pick up a reciever, and he has THREE brand new Evolution engines in the display case. There are three versions of this engine:

1. The Evolution trainer system, which is the one that comes with the Alpha trainer. The engine by itself comes with the flywheel and three blade Evolution prop.

2. The Evolution .46, which appears to be the same engine as the one above, but WITHOUT the flywheel and three blade prop.

3. The Evolution .61, which is bigger, and has no flywheel or prop.

I have read several complaints about the performance of the engine with the thre blade prop. Fact is guys, that system was not designed for stellar performance. The prop is designed for low noise, and slow speeds, so a trainer is easy to handle. If you take the Alpha, or any other trainer with the Evolution trainer engine and three blade prop on it, and put it in a dive, you will notice that the plane doesnt gain any airspeed. This is the whole point of that system, to have a no frills engine and prop that will keep the trainer at slow speeds so a beginner can keep on top of things. the guy at the shop tells me he is running one of the new .61 engines, and it has rivaled or beaten any other .61 he has run in its class. I havent seen it fly, but several of the guys in his club are saying the same thing.

You young engine men put this in your gray matter memory cells ! Some time down the road this engine will be a collectors item . If you can afford it buy one & put it away . I wasn't smart years back & missed my chances to buy engines that have greatly increased in value. Got to be better than ENRON stock ! MAX H.

Max, I'm just curious as to why this thing might be a collectors item. I know it's a neat looking engine and I suspect it's a good engine. I'm like lowlevel, I've seen guys on here who just don't get the concept of the .46 on the trainer system, in the simplest terms, it's supposed to run nice and fly nice. You don't buy that plane and engine to 3D.

tell ya what folks,i used an alpha trainer to learn, and i have purchased a couple of them that were destroyed in crashes,i have used the evo .46 on a couple other planes,a balsa usa phaeton2,and a sig smith miniplane,and got one on a WM P-51,my point....... take off the flywheel,press out the prop hub,put on the hobbico/tower .46 tuned muffler,or a pitts muffler ,put on an 11x6 apc,and enjoy. and,even though it will stir a stink,i will put any one of my evo .46's against an o.s. 46fx any time! they are very powerful and cheap to boot! later

Anybody using the .61 Evo? I was thinking of putting it in a Sig 4Star 60. I have the Extra Easy2 with the Evo .46, starts easy, no hassles works well ( I am a newbie, need simple things at this point ). Thanks

Michael

hobbsy: I think it will make the grade due to it's unique looks & what will be it's low volume of manufacture. We both know the sales will not match those of the larger manufactures. I have one located on the special dealers display stand & that should help it more yet. MAX H.

Any engine that emerges into this world sporting a DA (duck's ass) hairdo has earned it rightful place into the world of collectorship. This just might catch on with the teens as Honda's have.

Ernie, You hit it right on the head or should we say the DA ! Good job ! MAX H.

You must be talking about those Hondas those kids buy for $16,000.00 and then spend $12,000.00 more for hotrod stuff so it will run as good as a $1,000. Chevy.

Danny03,

I did the floats this weekend and have the following advice.

1. Do a search for Jim Casey here at RC Universe and check out his links for setting up planes for floats.
2. Following his advice and buy or build a set of floam floats. Pay attention to the details a set them up according to his instructions.
3. Have an experienced seaplane pilot take it off and reset the trims for you.
4. Have fun.

The Alpha handled the floats fine and took off and landed just fine. The Evolution 46 was easily up to the task. I was using a 10x6 Master Airscrew prop.

Well, just put a brand spankin' new Evo .46 on my Kadet LT40 taildragger. Fired it up last night, and it runs like a charm. Very smooth transition, and plenty of thrust with an 11x7.5 wood powerpoint prop. I did have to adjust the limiter on the low speed needle though, as I couldnt get it leaned out enough with the stock setting. Other than that, I had no problems. I fueled it, put the heat to the glow plug, and it fired up and ran on the first try with the starter. I wont get to fly it until Sunday afternoon, but I can already tell it is going to be a winner. Next to the little old Webra .40 I did have on the nose, this thing looks huge!! I'm thinkin' about ordering the Evo .61 for a 4 Star .60 project I just bought.

I have that engine on my Extra Easy2, runs great. I too am putting together a 4*60 (arf) I thought about the Evo 61, but it has not been out too long. Mind if I e-mail you to talk about our similar projects so not to disturb this thread? Thanks.

MSP1957:

I sent you a PM.

HI, I have an Evolution .46 in my p-51 hangar9 pts, but my prop brake, so I want tu put a 11x6 3 blade prop, do you think is ok? or I should change it for a 2 blade propr, I like the sound of a 3 blade but I don't know with which 3 blade prop I could get a good displacement. thanks.

A 10 X 6 three blade would be better for your engine. The engine will not pull a 11-6 three blade.

Enjoy,

Jim

My .46NT pulls a 12.25x3.75 with plenty of power. It has a Tower muffler on it and that gave it another 1000 RPM.

I wouldn't say in advance that the 11x6 blade would over load the engine, but I would suspect such a thing until I actually saw how it performed. Tach your engine well with something like a 11x7, or similar, and then try the 3 bladed prop and see how it tachs. You are going to be borderline with that prop and won't know until you try. Like W8YE said, maybe a 10x6 would be worth trying out too. Props are funny things. Maybe both will fly like crap. You really have to experiment.

Something that W8YE suggested for my 46NT- try either the OS A3 or Tower plug if you are using an OS 8. That was a world of improvement in my engine. I'll never go back to the OS 8.

I have both the .46NT and the .45 trainer system engine. Both are really superb engines that put out a lot of power. The .45 is an incredible deal at the prices they sell for.

Looking at the specs the 45 will turn the same prop at a higher RPM than the 46 Maybe cause of the flywheel???Anyway All I know is from my experience around these engines is there very good user friendly and put out the power of any 45-46 in its class. We took off the 10x6 3 blade and put a 10x6 2 blade back on and tached it out at almost 15,300 static A little much for a trainer and a new guy flying so we put a 11x6 in its place which seem to do very well .
The 61 is a good engine also user friendly ,but my buddy complains of a midrange rich spot ????
I wouldn't be afraid to buy one of these engines from what I've seen, one of the best deals thats come around in quite a while.
Oh and I have had one apart for cleaning they are a true ABC engine with front and rear bearings .

The Evo trainer engine has a bore & stroke of .87 (22 mm) and .77 (19.6 mm) and a displacement of .455. These are the internal dimensions of the OS & Magnum engines except they call them .46's. I understand the Evo glow engines are made in the same factory as the Magnums.

The Evo .46 has a bore and stroke of .86 and .80. It's displacement actually rounds off to .47. The .46 is a long stroke, smaller bore engine than the .45 trainer engine.

Evolution engines are made at the same factory as ASP and Magnum.

You are right about the .45; it screams with an APC 11x7. I have a 4*40 kit that I'm going to put it on when I build it. The flywheel actually slows the engine down, and adds weight. Take it off and forget about it. Also, remove the baffle from the muffler if you don't get a Tower muffler.

I had a Fantasy sport flyer that had a TT Pro .46, OS .46 FX, and then the .46NT. On the first flight, it was clear that the .46NT had way more power. The engine had only been run for a few minutes before the first flight on the Fantasy. Even then, the engine was slightly rough sounding for the first tank but smoothed right out after that. I used APC 11x6 props for all 3 engines at that time.

Both engines are forgiving if not tuned dead on. The crankcases don't seem to load up very much compared to other engines.

I have a modified Alpha .455 in my Cermark Bobcat...(it has the sleeve mods as per the 2 stroke mods thread )

W/ an APC 10 X 7 and Tower muffler it will turn 13,500 on 10% and over 14,000 w/ an APC 12 X 4 FWIW

I took the flywheel off too...

edit: I had to put bearings in it fairly early in it's life as it was in our club trainer and suffered some abuse...( little or no ARO and un-balanced props due to many ground strikes )

Evolution 46 runs back wards. I have a P51 pts trainer with Evo 46. Engine is easy to start and ran great until I burnt the plug by plugging in my glow starter to 12v. Replaced with a longer plug. Didn't start very easy, but ran okay. Got original plug and it runs great, but wants to run back wards. Any clues. I noticed in some of the postings that you guys are flipping prop clockwise to start vs counterclockwise. Obviously, novice.

Thanks,

Brian

Try back flipping and see what you can get away with.

Most of the time people just bounce the engine up against the compression stroke from the back side and the engine fires, making it run forward.

I use an electric starter and do not have this problem.
