    Got my ERBE and I'm going to change a lot of things

    First thing I did before even trying it was to take the TQ transmitter and receiver and install that in my son's Mini T. Then I installed my DX3R receiver, an ACE single servo, Proline steering arm and EC3 connectors. I also made a custom antenna tube.

    Now! I have to say, what demented evil mind ever came up with this brushless system? This thing is scary, I was afraid to hit somebody with it. It was a nice day out and many people were outside walking their dog or playing with their kids. I tried the truck to see what it could do and found out that... It could do some damage so I took it inside and put it away This thing is going to be fun but I think 4S will be sufficient for me in the future.

    The pics:


    And after it's first run on the street and grass.



    I'm going to change a lot of things on this truck in the next few weeks. First to try to improve the durability and handling of this truck and second to bring some attention to myself. Stay tuned, an ERBE build from me should be interesting.
    It's been fun. See ya.

    At 4s you won't be able to properly test that custom slipper disc you made. I guess you'll just have to send me one for a proper trial.

    Well I,m not saying that I will never run 6S again Of course I will. But I intend to try racing with this thing and 4S will probably be enough to clear the biggest jumps.
    Here's my ERBE 8 hours after I got it. I just can never leave well enough alone



    But I guess it's good to check everything out because after only one 10 minute run, one of my diffs, the front one sprung a leak. And there were a couple of screws that were stripped with the plastic of the chassis melted on the threads.

    It's been fun. See ya.

    Very impressive, Ive just seen some of your pictures with the LST and Hyper7 diff. Superb idea on that.

    I will definitely be keeping track of your progress.

    Something I did while the chassis and rockers are taking a bath in black RIT dye. A 3 mm thick carbon fiber motor plate.



    This gave me the opportunity to install the carbon fiber slipper pad I made earlier this winter. I had an idea of making a full disk and then I saw someone actually did on the RC Monster forum out of circuit board material. I tried to find the thread but I couldn't. Anyway, he did it first and he said that his circuit board slipper pad worked like a charm. I made mine out of CF. Still don't know if it will work.



    Gotta go get my son from daycare. More to come later.

    That's a sweet looking motor plate. It looks very professional. How do you think it'll hold up to the torque of the motor screw on it?

    Is the cf motor plate you made any stiffer than the stock aluminum one? I ask because I notice mine can flex noticeably with a little pressure and that of course changes the gear mesh.
    Hopefully traxxas or someone will offer a thicker motor plate for the new revo tranny like they did for the old emax tranny.

    Don't know, everything you will see in this thread are experiments, only time spent racing and bashing will tell if anything I will show here will hold up. As for that motor screw, CF is stronger, stiffer and harder than aluminum. I don't think it will be a problem but then again, that motor's torque can shred any part with enough abuse. We'll see.

    Yes it is. I noticed that the aluminum one had quite a bit of flex two.

    This slipper looks very impressive, but I think that the friction factor of the carbon fiber is lower than the stuff that a regular slipper is made of - so I think it will not have better performance. It seems like you will have to tighten it all the way...
    Anyways- this is interesting, keep updating on how it performs

    Lst2 Diffs

    What you see in the bulkheads are Losi LST2 diffs. They are 1/8th scale monster truck diffs. Very tough.
    The power of the MMM on 6S apparently shredded a few of the stock diffs so I decided to follow this person's lead on his project of putting LST diffs in a Revo. He posted this project on RCM, just click his name to see and read through it. This is and experiment as I have no idea if the bulkheads will hold up. The LST2 diffs will not be a problem; these things are massive and very strong 1/8th scale monster truck diffs. My concerns are with the material that was removed from the ERBE’s bulkheads to make the LST2 diffs fit in there. Only hard bashing and racing will confirm if the bulkheads are still as strong as they were before. The thumbnails will lead you to a bigger pic with a description underneath of what was done.

    I will use Traxxas Summit shafts all around this ERBE. I also want to try and fit them for the center shafts. This is what I have done so far. I put two set screws on either end of each shafts with blue Locktite and for added protection, I shrink wrapped the cross pins. The shrink wrap idea is from Dragonfueled in his thread



    This is where I am for the center shafts.

    Winters are long in Canada eh! Gotta have something to do. I got something for the tranny two.
    I have a 1/8th scale center diff in it.

    This center differential has been discussed many times on these forums and it all started with a guy naming himself ‘’CowboyRay’’. He made an 8th scale CD using a Thunder Tiger TTR S3 buggy center differential. His design required extensive machining to be done and was financially out of reach of many. Some people tried to take over this design and tried to market this CD but the financial aspect was a problem again. It was just very expensive to produce and the sale price was high. Cowboy made and sold a few hundreds of them and then stopped when Traxxas came out with their own version of a center differential with rear brake. Then I saw on the RC Monster forum a guy named ‘’sjcrss’’ made an 8th scale center differential with parts of an Ofna Hyper 7 buggy CD that did not require the help of a machinist or machining equipment. Having at least a drill press or access to one helps a lot though. The hardest part of making this CD is definitely making M3X.5 threads in hardened steel. I bought a full carbide tap to help with this. It is expensive but I use this size tap so often in this hobby that the purchase was justified. The thumbnails will lead you to a bigger pic with a description underneath of what was done.

    A few little details on this build.

    PUSHRODS AND TURNBUCKLES

    I am using the Traxxas aluminum red pushrods and Traxxas aluminum red turnbuckles. I would rather have them black but the black pushrods are not out yet. I changed to Traxxas red pushrod spacers since the ERBE came with blue ones. I also like to use the TRA5348 turnbuckle rod ends on all the turnbuckles and the pushrods. They are the biggest and bulkiest rod ends used on the Revos. They are usually used only on the rear turnbuckles but I like to use them everywhere. You can recognize them by the small ring around the base of the ball end.


    It's been fun. See ya.

    ROCKER POSTS

    I don't know about you but when I want to take the rockers arms and this happens, it annoys me.




    The P2 progressive rockers will be used but this is a small modification I like to do to the rocker posts. I take out the M4 button head screw, I make sure the rocker post is firmly screwed to the bulkhead. Then I take an M4X.7X16 mm set screw and screw it firmly in the rocker post with red Locktite. I then use an M4 Nylok nut to secure the rockers. Whenever I need to take a rocker out, the post stays in the bulkhead.



    Here is something I do to the rear body post.

    REAR BODY POST

    There’s not much to say about the rear body post but I just wanted to show what I did to it. The body post used on the ERBE is the same as the 3.3 Revo with Easy Start so it has this orifice in it for the Easy Start plug. It is not used for the ERBE so I sanded it off with a sanding drum.



    BULKHEADS

    I have a tendency to over tighten screws sometimes. Especially with the plastic bulkheads. I feel these need to be sitting as tight as possible against the chassis but I often stripped the threads in the plastic trying to do so. I installed some Dubro brass inserts to deal with this problem. Now I can torque those screws very tight and I believe that this helps make the bulkheads sit very snuggly against the chassis adding to the overall structural strength.
    I used the 4-40 inserts for the screws that go through the shock towers and 6-32 inserts for the rest on the screws.

    Part 1

    ZERO SLOP 17 MM OFNA ADAPTERS

    I posted this before in another thread. The Ofna adapters are tough and cheap. The Traxxas adapters are very similar except for the splines. Both of them have slop that gets worse with time because they get grinded by the threads of the stub axles. There are other systems out there that require the use of 8 mm stub axles or stub axles with no threads but they end up being expensive, although they are very good. Also there are cheaper styles that work great but I started with Ofna before any other systems came out and with the modifications I did, they have been working so well that I don’t see why I should change anything. The thumbnails will lead you to a bigger pic with a description underneath of what was done.

    GETTING RID OF THE LOCKTITE

    Here's a couple things I do to stop the need for Locktite. Some slots Dremeled in the nuts, they bite in the wheel's plastic and they don't come of by themselves and a groove for an O ring to keep the set screw from backing out. This has been race and bash tested for a long time. It works.

    SPECIAL TOOL

    I made a simple tool to screw in or out the little tubes I made. It works great and doesn't damage the part like a flat head screw driver can.

    Other Details

    This is something I always do with the axle carriers. I use a longer screw and a lock nut.



    The full ''Steve Slayden Steering Mod'' was done on this ERBE and also the front bulkheads have been modified to accept 5 caster clips.



    Variable damping #2 shock pistons will be used on this ERBE, the rebound holes have been enlarged to 2 mm. I like a fast rebound.



    A few carbon fiber parts will be used also, a rear bulkhead tie bar, a rear wing tie bar and maybe a chassis cover plate for the hole left by the second servo that won't be used.



    Sway bars will be installed and I will go into more details about that later.

    TRAXXAS PAYS ATTENTION

    I'm glad this idea made it to production of the shock tower to help put the shocks back on. A little taper in the plastic, an idea posted many times on these forums.

    I looked at the ERBE body and I thought, this thing screams ''vent me''. So I made a few venting holes to have air circulating to cool the motor and MMM and to keep air from being trapped inside the body.



    I also installed the little carbon fiber plate to cover the hole in the chassis left by the unused second servo. This plate was originally made for the 3.3 Revo and the holes didn't line up exactly so I enlarged them and used the cool Traxxas servo screws to secure it. I might use this plate as a mounting spot for my personnal transponder later.



    The shocks are rebuilt with blue rear and silver front springs and the #2 variable damping pistons. I put 60 weight oil in them even though it is still cold out but it will warm up very soon and it should be fine then. Until then the suspension will feel a little stiff.

    Good day eh!
    It's been fun. See ya.

    The Slayden steering mod is a must for racing IMO. For bashing you could do without it I guess but it helps the truck so much, why not do it. Anyone who frequently send their truck cart wheeling should learn to better control their truck first though. The extreme steering throw of this mod will make the pillow balls more susceptible to popping out of the carriers.

    Thanks. I just read a thread by danielhr77. He did a really cool thing to his MMM's switch. ON and OFF in clear view so now he is sure his MMM is off when he wants to connect batteries. I didn't have that plate he had so I took parts of decals I have and came up with this. Also, if you're like me and keep whatever decals you get with kits and parts and RC magazine subscriptions, check them because sometimes they have cool little decals made just for a switch that says ''ON/OFF''. I had one on a Tamiya decal sheet dating back to the early 90s but it didn't stick anymore so I couldn't use it.

    Green means ''GO''. Red means ''NO GO''.

    It's been fun. See ya.

    To everyone that have the ERBE or the EREvo. I would like your opinion on the chassis. I think it has tons of flex. Flex can be good as it will give instead of brake but I find that this chassis is like a wet noodle. I'm talking about the front and rear ends. The middle has a lot of ribbing underneath and the center skid helps a lot. But the front and rear ends that lock in the bulkheads are very flexy. Once the bulkheads are on, it seems rigid but it's the bulkheads holding the chassis in place. That brings me to think that the bulkheads will snap more easily since the chassis' front and rear ends have too much flex to help the bulks dissipate the forces of impacts during extreme suspension movements. It's just an observation here, maybe I just think too much.
