    I installed my summit axles tonight

    For those interested I got Ebay summit axles tonight and installed them into my Nue mmm combo brushless E Revo. First I gotta say these things are really nice and beefy. They look like they will take some serious power and there very smooth and bind free. Yes the summit uses two different length axles. I just mounted the shorter one in the front where the torque isnt so crazy. I simply pulled the two halves apart a little and the fit perfect. The axle still has plenty of slide left in it so I dont see it affecting anything at all. The rear bolted rite up perfectly. All I did was shrink wrap the inner and outer cross pins for the cvd part just incase the inner set screw came loose I wouldnt lose the pin.

    All in all they seem like the answer the my prayers as far as axles go.

    Thats a pic of the front streched to fit. The rears are perfect. At least now if the little set screw comes loose the cross pin cant go anywhere. Heck with the shrink wrap you probably dont even need the setscrew.

    I have some vehicles that use a set-screw similar to that one. With a bit of blue threadloc, I have never had one come loose. The shrink wrap isnt a bad idea tho for extra protection. I just wonder if it will stand up to the abuse.
    keep us posted!
    be nice.

    Dragon, just to clarify... there weren't any fitment issues with the summit axles where they mount to the revo diffs? Just wanted to make sure, if there isn't this would be the perfect setup for the erevo. Good idea about the shrink wrap and thanks for sharing.. good thread.

    the plastic looks to be a little thicker around the cvd. i think it accualy might be stronger. great idea with the shrink wrap

    no problems at all mounting them to the revo diffs. They slip on just like the stockers. The area where the pin goes through is obviously thicker and should be an awesome axle for brushless power.

    I was killing the stock axles. The plastic ears around the u joint pin would just elongate till it snapped. only the rear were breaking the front were fine. Thats why I put the shorter axles in the front.

    Thanks for the comment on the work area. I bought the house in april and finally had a basement to spread out in lol and spread I did. Theres actually more to the right then the pic shows but the meat of it is in the pic. Some guys have there smoke room or there bar or game room, lol I have my rc basement.

    i just got back from an empty field with a lot of gravel and dirt, real cool place but i snapped 2 shafts. snapped one front and one rear, both in the same spot where the pin for the u joint mounts to the axle. i cant decide if i should go with the summit shafts or traxxas CVD's. im not worried about price, just something that will stand up to the power.

    Are the ends where they attach to the differential metal or plastic? Do you think those would fit in an e-maxx?

    im in the same boat ive broken a front and a rear in the same spot......lemme know which ones you decide to go with...im leaning towards the traxxas cvds

    im actually thinking about the summit's. look more beefy and a guy at my LHS say the continuously pop out of the cups, but other than that theyre good. but the metal sounds nice too. i just want to see if someone has experience, and i may call traxxas tomorrow to get their input.

    The ends that go to the diff are metal. I've tried both now and prefer the summit axles. I think the cvds have more all out strength. But the summit axles are easier to remove and install. I had a good experience with the traxxas cvds though. I also like that the summits work with the long travel suspension.

    so the metal CVDs cant work with the long travel suspension?

    The metal cvd's have been known to pull out of the drive cups on the brushless revo, especially folks running rpm suspension arms that allow a little "movement" as they take hits during impacts. From what I can tell, the summit axles are gonna be the ticket...

    i just bought a set of summit shafts, hopefully theyll be here by the weekend. ill let you guys know how they hold up. i decided on these over the CVDs because im using the long travel and the CVDs arent telescoping, which may be a problem and im also using RPM arms which dont help the popping cup issue. and everywhere i look a set of shafts are $50 and $6 to ship, and i just found one for $36 and $5 shipping.

    I got mine today, two full sets actually so I have 4 long shafts and 4 short ones. The short ones will be for my nitro Revo. I never paid more than $10 per shaft shipped. I just bid a max amount and let the auction go on. If I got outbid, I just let it go because I refused to pay more. I did dragon's trick with the heat shrink and also went double set screw on all the pins. Here's a pic of a shaft that will go in the rear of my BL ERevo (whenever I get it ) They are very nice and they just look really durable. Can't wait to try them.



    Can anyone tell me what is different about this shaft other than what I mentionned before?

    just got my summit shafts on and theyre pretty nice. the fronts are extending a little since theyre the short ones on my LT suspension, but theyll be ok. i wrapped them in shrink wrap as the others did, but ended up taking it off because the motion was not as smooth. i just put some thread lock on the screw and hopefully i wont have any problems.

    is the aim of shrinkwrap to retain the screws ? then I bet threadlock or even loctite (CA) is much better.

    the shrink wrap doesn't retain the screw, it retains the pin in case the screw comes off. Threadlock on the screw will keep the screw from backing out but just in case it still does, the shrink wrap will keep from loosing the pin. So it will be a good idea to check often that the screws are still in their place.

    thats why i figured if you just locktite the screw, then the screw wont come out, and if the screw doesnt come out, then the pin wont come out, so i dont need the shrink wrap if the screw doesnt come out. kinda like an A=B and B=C, so therefore A=C

    I have had threadlocked screws come loose in the past, not often but it did happen, so even though I put threadlock on my set screws, I decided to still put heat shrink around the pin, just in case. Better safe than sorry. $5 to replace that lost cross pin or a few pennies to replace a lost set screw.

    Way I figure, if shrink wrapping those type of shaft pins is good enough who race, its a great idea for bashers as well.. anything to keep the run time up, and the wrench time low...

    Summit shafts picks up the slack

    It used to be that I needed to turn my spur gear almost half a turn before the wheels started to move, this was because the drivetrain had so much slop, even with all new drive shafts, due to all the U joints. With the CV style Summit shafts, as soon as I start to turn my spur gear, the wheels start turning. These are the short shafts I installed on my 3.3 revo.

    That was one exciting video but I agree about the slop the universal joint shafts get in them.
    I wonder if the summit axles could be used on the transmission outputs as well? Since they are slider shafts you could possibly just cut them down to the length they need to be? You would lose the rubber boot but the stockers don't have that either.

    I know the vid is boring They are beefy shafts, I don't know if the clearance under the chassis and in the bulkheads are enough.

    Looking at it closer, I think it could work. We'll have to try it

    I'm definantly going to try it once I get mine put together, unless you come back and say it can't work,lol

    They're cheap enough it's not a big deal if it doesn't.

    So will the long shafts work?? I found the long and short ones on tower but just wanted to know which would be better..

    Thanx

    The long shafts fit perfectly. The short ones have to be stretched a bit. So the right choice for the Revo is the long ones. Did you find complete shafts on Tower or do we still have to buy the separate parts?
