    RE: Anyone Tried The New Evolution .60NX?


    ORIGINAL: bob27s

    MJD.... just a heads up.

    Jett discontinuted the 60LX engine this month. The regular SJ-60L is still available for now. Dub is introducing the new ''long-rod'' SJ-56 in a couple of weeks, it is based off the new generation racing engines. So far testing has been great, it gets the best of both worlds. Longer rod gives it the torque of the 60L - and its super user friendly - and also turns the rpm the 60LX was capable of.

    I am waiting until after the holiday to get ahold of the Evo .60 .... looks like a sweet engine, and I know it was well designed. I have to do some jett muffler testing on it so I can get some data on prop/engine/exhaust combinations. The OS55AX turned out to be a great match with the jett muffler on it. No doubt the Evolution 60NX will match up well too.
    Cool, that will be interesting data. Hope it turns out to be a decent sport go-fast combo. On paper sounds like just the thing for deltas and Quickies.

    I have a Jett stream muffler on the way to play with. It should make the Sundowner Move out pretty good.

    Has anyone found a header that will fit the 60 NX? Stock muffler is very restrictive.

    According to Horizon Hobby Disturbers the Evolution .60 NT and the NX have the
    same exhaust mounting. So the #6860 should fit or any of the exhaust for the
    OS.61 FX motor exhaust mounts.

    Have you read the manual!! http://www.horizonhobby.com/ProdInfo...ion_Manual.pdf The manual tells you to use the MACS Pn# MAC2591 Header (OS .46FX) and MAC1250 Pipe (Muffled TP 8.5cc: .45-.60). The bolt spacing is 37MM which is the same as the OS .46FX/AX -.55AX, TT Pro .46, Magnum .46XLS, Evolution .46, .52.

    Horizon and Macs Products both gave you the wrong imformation, since this engine comes with the same part number muffler as Evolution ships with the EVO .46, and .52. It does not have the same bolt pattern as the OS .61FX like Macs told you!

    Here is mine with a JETT Muffler and spacer from JETT Engineering meant to tilt the angle of the muffler to allow you to install it in the Sundowner 50. The muffler shown is designed for the OS .46FX/AX-.55AX and any other engine with 37MM center to center spacing.

    No, haven't read the manual as I don't own one yet but good info and thanks for posting!

    So if I have a 46AX on a 48" plane with a pipe, all I would need is an 8.5cc pipe and I can probably use the same header length (or close to it). My pipe is an old (early 80s) 6.5cc pipe so the 8.5 would probably make the header length I'm running on the little pipe still useful on the 60! That would wake that plane up. I'm getting 14,200-14,300 with an APC 10x8 and would love to run a 10x9 or 10x10 at close to that!

    RE: Anyone Tried The New Evolution .60NX?

    I cleaned up the ports a little too. I am hoping to prop it in the 15,000 rpm range. I just hope bearings can take it. It has metal caged bearings, and I am presently looking for some phenolic retained bearings.

    Polymite Retainers (plastic) works great. Phenolic retainers are falling out of favor and getting rare.

    That sounds like something I would like to do. I've ported my share of cylinder heads in my time but have no idea where to start one one of these little guys! Can you post some better close ups of what you have done and maybe with some arrow thingys pointing at your work!

    thanks!

    I just blended the ports to make them flow better. I did not not change the actual size of the port window.

    I wish you would have run it to get a base line before smoothing the ports out.

    All you have to do is subtract 200-300 rpm and you have your base line RPM.

    I expect that a Tower .46 Muffler would fit the .60NX? Any views? Is this a good inexpensive upgrade? Still have not run mine.

    RE: Anyone Tried The New Evolution .60NX?

    The Tower muffler will bolt on but the chamber volume is small for a 60 and the effective tuned rpm will be too high for the muffler to be as effective as it is on a 46 size engine.

    It might not be as effective as it is on a .46, but it surely will be an improvement over the stock muffler which also ships with the .46 and 52 Evolutions.


    If you want really good performance either get the Jett Muffler PN# JS40TT which Dubb also uses for his Jett .60L and the OS .55. You can allways opt for a TUNED PIPE which Horizon recommends for it. Here are the PN#'s for the Pipe and Header straight from the engine Manual.

    RE: Anyone Tried The New Evolution .60NX?

    Update

    I ran a few more tanks through my Modded NX, and my friends stock NX back to back today. They both now have (3) 16 oz tanks ran through them. The fuel today was 20% again. The plug was an OS#8, after the stock plug blew right off the batt with stock muffler in the stock engine. The stock mufler ran like total crap, and the testing was terminated at the beginning of the second tank. It ran like it was way rich, and you could not lean it out, or it would sag. I killed the engine, and checked the plug, and it ws half dead. i installed a New OS8 and the Jett Mufler. The same Jett Muffler and Sundowner 50 spacer by Jett was used for both engine runs, since we are waiting for the other one in the mail yet.

    Stock .60 NX w/stock muffler
    APC 10-8 12,800 Peaked the RPM, but the engine acted way rich and was hot. Fried the plug.
    APC 11-6 12,600 Peaked the RPM, but the engine acted way rich and was hot. Fried the plug.

    Stock .60 NX w/Jett muffler The engine was instantly transformed. I said there, do you believe me now. My friend pitched the stock muffler for the dumpster.
    APC 10-8 15,200 Peaked
    APC 11-6 14,800 Peaked

    Modded .60 NX w/Jett Muffler
    APC 10-8 15,500 Peaked
    APC 11-6 15,200 Peaked
    MA 10-7 15,900 Peaked "Buddy ran for cover as he thought it was going to blow up (Very noisy), and I was not sure myself that it would not myself. I just did not want
    to chop my arm up with shrapanel this time. I think I could of squeezed another 100 out of it, but I was not going to chance it.

    The conclusion on the Modds are still a little unknown. The engine is stronger by little, but I do not know if it is worth the time to do it. Mine does seam to be a little snappier down in the low speed throttle responce area.
