    Agreed. OS 8 or Rossi R4 plug. 5% nitro 20% oil with some castor! APC 9x7 and a Jett Muffler 15,500 RPM.
    Don\'\'t just stand there, go get some glue!

    I could rip the RPM's up higher with a smaller prop, but I hate to scald my Webra. Heard that Webra went out of business.
    12,600 rpm is low rpm, not high. 15-16k is nothing - just average sport rpm. You can start worrying about rpm as you approach the 19-20k mark. You don't "scald" 2-stroke engines by reducing prop load and running them faster - in fact as a general rule they run cooler with smaller props. Lugging them down with oversize props is more harmful esp. if the engine is running on too high nitro and and a too hot plug which drives it towards preignition. As suggested shoot for the mid teens, you'll see more power from the engine and it will be happier.

    RE: OUTLAW from EXTREME FLIGHT

    Has anyone powered an outlaw with a .25 sized motor? Does the balance work out better? Do aerobatics improve? What size props have you used and what kind of speeds do you see? I'm looking more to aerobatics rather than all out speed.

    RE: OUTLAW from EXTREME FLIGHT

    Think of a .25 having the same size case as a .32 to .36 size engine but potentially heavier with a thicker liner.
    I'm not sure if this true with all brands, but in the past this is how it was with some brands.

    The .25s I have ran were decent, but pretty tame. With a 9x4 or 8x5 prop you could expect OK performance out of most of them.

    RE: OUTLAW from EXTREME FLIGHT

    It balances perfectly with a .32. If my memory serves me correctly, Jerry Smith designed the plane around the OS .32F. I can't really see any advantage to using a .25.

    RE: OUTLAW from EXTREME FLIGHT

    The OS .32 came from the .25 so they are about the same weight. I think the .25 was rated at 1.0hp and the .32 was 1.2. Later the .25FX was shown with a lower power out, about 0.85hp.

    As a general rule, .32's are in the same engine block size as the equivalent .25's. Much the same as .40's became .46's, then .50's, then .53's etc etc, all in a .40 size case. Well, now we even have .60's and a .76 in a .40 case. And .90/.91's in .60 size cases.

    So rather than .25's being overgrown .15's for example, they are in the same general case size and weight class as .32's. I do not know off the top of my head what the exceptions to this are, but as a general rule of thumb I believe you will find it holds true.

    RE: OUTLAW from EXTREME FLIGHT

    Since I happen to have a .25FX and a .32SX sitting around, I took a few pictures for comparison. Ignore the oil on them, as they have been pickled for future use.

    The .32 is always pictured on the right, and the .25 is the one with the spinner and glow plug. As you can see, they aren't the same case, but they are very close in size.

    RE: OUTLAW from EXTREME FLIGHT

    How do your two examples compare in weight? I dug up some specs online, they are subject to the advertiser's error:

    OS .25AX Weight: 12.6oz (357g) with muffler
    OS .35AX Weight: 12.8oz (363g) with muffler
    TT Pro .36 Weight (w/muffler): 11.4oz (323g)
    ST G-34 Weight with muffler: 363g (12.8oz)
    Magnum XLS .36 12.? oz with muffler
    Jett BSE .35 AAC 13.9oz with muffler (tuned exhaust, not a regular can)

    In the .40-.50 class, here are a couple of examples for comparison:

    Sport-Jett .50 16.5oz
    OS .46 AX Weight: 17.2oz (489g) with muffler
    TT Pro .46 Weight (w/muffler): 17.01oz

    I don't suggest that .25's and .32-.35's have identical cases, but in terms of engine weight class they appear to be pretty close.

    Sorry MJD, I don't have a scale small enough for measuring the weight of engines with any precision.

    No worries, just curious. I think the engine weights above tell a lot of the story.

    RE: OUTLAW from EXTREME FLIGHT

    Outlaw owners, a couple q's re my Outlaw ARF/ Webra 32+mousse can/ Omega 15%/ 9x6.


    Starting the Webra 32/mousse...hand-flip or elec starter? If elec starter, that means a prop nut or spinner?

    Fueling....can't see the tank. How to know when fueling complete? On a reg setup I guess you get a few drops out the stock muffler...maybe on this baby you pull the pressure tubing off the nipple of the header til fuel comes out?

    thx
    Jeff

    RE: OUTLAW from EXTREME FLIGHT

    You can start just about any decent glow engine with either an electric starter or a chicken stick. I prefer the elctric starter method because I am lazy, but a properly tuned engine is no trouble to flip start. If you use the electric starter you will need a spinner or a prop nut/hub of some type. I prefer the cone shaped prop nut on this design.

    Please don't take offense to my question, as I mean only to help, but this isn't your first airplane is it? I see through most of your posts that you fly helicopters. Although that takes quite a bit of talent, I can't recommend that your first fixed wing aircraft is an Outlaw.

    Generally, it's not a good idea to run over 10% nitro in a Webra airplane engine.

    Duck, great question....and no it isn't. In fact I've been ripping it up very fast and very quick w/ both my Stryker and my Grayson Funjet and have become fairly decent with those in high-speed stick-jammin. I hand launch em both. I also 3D-fly my Sabre 47 profile (AX55). So, lookin to try something a bit...'different'. But thx for the heads-up. Outlaw ain't a trainer!!!!

    Well, crappo. I sure hope I don't have to lug around a 3rd fuel type to the field!!! 30% for the heli, 15% for the plank, and now a third gallon?? Yikes!!! Aint there something I can do, like a head shim???

    RE: OUTLAW from EXTREME FLIGHT

    You can run the OS .55AX on 10%. You will not lose a significant amount of power.

    I have never tried a head shim on anything, but I don't see why it wouldn't work.

    RE: OUTLAW from EXTREME FLIGHT

    I agree, the AX55 will run fine on 10%. I live at 4500', and 10% is not enough. I raise the compression in everything and run 15%. If you live over 2000' I would run 15% in the Webra and the AX55.

    And, if it's not too hot. About 5 years ago when the Webra 55 GT (round black head) were all the rage, guys were just thrilled with their engines in spring and fall conditions, then when it got in the 80's to 100's they were burning plugs, couldn't tune them, chasing plug heat ranges, the engine were sagging even when the mixture was right. Then it was discovered when run on 5 or 10% and they were even stronger than the cool days on 15%! There were some guys that just kept pushing on 15% saying it needed more time to break-in, and eventually the engines would settle down.....after losing pinch or hammering the connecting rod thus moving the rod hole centers closer, not the right way to lower compression in either case.

    The Outlaw is very easy to launch you will not need an undercarriage. That said I did make a larger twin version and made a dolly for it.

    The CG is were it is and it balanced fine with the way the servos and battery were placed. No additional weight was added to balance it. It flys very well.

    RE: OUTLAW from EXTREME FLIGHT

    Has anyone experienced the firewall coming loose?
    Mine broke loose from the sheeting on the maiden flight. I've now fiberglassed the backside of it.

    137mph according to the Eagletree with Jett 35 and 9x6 APC. That's about 24k in the air! It was about 18000 on the ground. Lots of unloading!! This is the engine's first flight.
    Can't wait to see what it does with 8x7 prop and well broken-in.
