    RE: New Evolution 10cc gas engine

    It looks like it might be. I look at the Saito manual for the 57cc engine and this is the tubing that is recommended, so I would say that it is the 1/8" id tubing for that size of engine. They don't list any specs on it. Jim

    is this the same fuel tubing

    This is actually a form of NBR, not Viton tubing. although it works well it is not quite the same.

    RE: New Evolution 10cc gas engine

    I'd like some advice from experienced flyers who've flown the 10GX on whether this would be a good engine for my second plane.I've been learning to fly on a Sterling Gazariator, an upsized Fledgling that I built in the early '70s but never got a chance to learn to fly until being retired.It's got a Fox Eagle .60 (version I), also from the early 70's.I'm finally starting to build my Sterling Lancer SL-62, the other plane kit I got back then. It's designed for .60's, with a 62" wingspan, 700 sq. in., with 1.25 in. wide strip ailerons.The wing is low mounted, symmetrical, constant chord, no dihedral.The box says the "flying weight" is 6.25 lb, but isn't specific about whether that is just the airframe or includes the engine.I know the 10GX would be underpowered for an experienced flyer doing advanced aerobatics with this plane, but I'm not there yet on the learning curve.This will be my first plane without the flat bottomed, shoulder mounted, 2.5 in dihedral wing I've been learning on.I've got good instruction, at a club, with a buddy-box.If this engine will fly the plane safely, allowing me to get used to flying this type of airframe, it looks like a good way to go.I don't see another gas engine on the market that wouldwork inthis planeas well, and I would like to get away from glow, but still like the idea of an IC power plant.Any thoughts on this would be appreciated.

    RE: New Evolution 10cc gas engine

    From a power point of view this engine would fly the airplane just fine, even for more advanced aerobatics. The Meridian is slightly larger and heavier (7-1/2 to 8lbs) and this engine moves it along very well. 

    Have fun!

    Pete,

    All NBR is not created equal. So much depends on compounding the rubber. I'd tread carefully.

    Viton is bullet proof in this application but is expensive and I haven't really found the right size for the small gassies

    I've found a different solution that really works well. It has remained flexible inside the tank and outside the tank for going on 4 years now, is sized correctly with a 0.110" ID and is inexpensive at 75 cents a foot (+S&H). Anyone interested, please shoot me an email direct to my email address

    I also carry great (no leak) 8 ounce tanks that are perfect for the10 cc gassie. There's a genuine walbro klunk in these. A ready to run tank is around 15$ +S&H mostly because the klunks are expensive. If you want to use your klunk, fine, and you'll save 4$

    Regards,
    MattK

    RE: New Evolution 10cc gas engine

    Got a question for the experienced Evolution 10cc operators. How do you think this engine would perform on a GP 60 size big stick?  I now have a Magnum .91 FS on it and thinking of going to all gas engines.

    Matt,

    Thanks for your post about NBR. You are correct and that's why I said it was 'some form' of NBR. We have the replacement Viton in our warehouses now just waiting to be put in stock for those that are looking for it. 1meter and 3 meter packages ... and yes it is about 3 times as expensive as your tubing. When doing the Development and release of this engine we elected to put the more expensive tubing in the package because it clearly performed better than anything we had tested.

    Genuine Viton tubing for 2.25$ a foot is great...Nobody has it that cheap. A 3 meter length for around 25$ is a good buy.

    WLM189,
    Out at our field, we are putting 20cc engines on the GP big stick or similar types. I have a DLE 20cc on mine, you might be disappointed after using the 90 four stroke. But thats just my input, Jim

    RE: New Evolution 10cc gas engine



    I like it, ski's and all.Sounds like a dead stick, any clue what happened? how long did you bench run them? The reason I ask is I am loading my b-25 with 2 of them.
    Either way, thanks for posting a flight video and looking forward to the small powerplants.

    If staying under six pounds... it will do unlimited vertical. I don't know how much over six will still obtain unlimited.

    RE: New Evolution 10cc gas engine

    Thanks for the insight Jim. Think I'll hold on to the .91 for a while. It has a fairly sluggish up line. Might try a different prop on it.

    RE: New Evolution 10cc gas engine

    yea im sure it want do unlimited vertical,but i think it will fly it really well..to me your best 3d planes have four stroke engines..the twist i have with saito 82 has a 13 x 7..been wanting to put 14" on it,,i have been practicing 3d moves with it on up in the air so i want get myself in trouble..i think the 2 stroke engines make better flyers instead of 3d anway..one of the other guys said it had as much power as os 55,i think dave said that,so it should be fine.

    yea i haven't flown my engine yet ,i'm wanting to order the pitts muffler for mine.but i think you are gonna be impressed with it from the testing ive done on test stand.if it flies as well as it runs on the stand,the throttle response is really good and clean..

    RE: New Evolution 10cc gas engine

    I did get a telemetry tach installed and promised an unloaded flight number. With the APC 14x4 funfly prop, I'm showing slightly better than 9k static and slightly more than 10k in the air on the flats.

    One issue I've not seen commented on and don't know yet what to think. I've now sixteen flights and have noted that the HS needle has needed backed out almost incrementally a click or two each outing for the last several. I've never owned an ABC engine and don't know if that is typical of break in. Along with that change is the great reduction in the black goo that has been noted. There has been no performance decrease. The engine is now easy enough to hand start that I'm no longer using a starter.

    Did you happen to get an AUW of that plane? what prop? I am also curious as to what caused the dead stick. I need to figure out what throttle servo I want to run still.

    RE: New Evolution 10cc gas engine

    I transfered this 10cc engine to an EPO F3A plane to fly in places where there is no runway for take off and landing, but hand launch and belly landing on slopes.  1.4m, 2.5kg, 12*8 APC, plenty of vertical power. this engine works perfectly right out of the box, easy to manage and adjust.

    Has anyone considered mounting this on a profile? I am kicking around getting one of these engines and putting it in a kit built OMP Katana (old) or restoring a H9 twist 40 up in the rafters.
    *

    An OS 55AX weighs 18.5 oz with muffler. The 10cc weighs 22 oz with muffler and ignition, and you still need a battery or IBEC to power the ignition. The Tech-Aero IBEC weighs about an ounce, so your looking at 23 oz minimum vs 18.5 oz. for the glow. That could be a good thing (kinda) if your profile is tail heavy.
    I think you can get that 3 ounces of weight back by carrying 3 ounces less fuel....don't forget about the fuel difference, its not really a weight issue. As a matter of fact, you now have ability to move your ignition battery and fuel tank around more than with a glow, so you are more flexible with the weight location plossibly avoiding adding lead to the tail in some models...weight is not a penalty with this engine in my opinion.
