Drivetrain Woes

[What's_nitro?]

Ahh but, when everything is upgraded, that "weak" link may be strong enough. Or enough so that failures are few and far between.

eventually i will be putting in the RCM hybrid diffs as i have already torn up a stocker and had to replace it. i will have to look into kershaw designs and see if they might be able to fab something up for me driveshaft wise.

Look at it this way, wheelies are not as hard on driveshafts as the great grip and leverage that the extended wheelbase puts on the truck. I would set your slipper slightly looser. Not much. Also limit your full throttle starts on high traction surfaces.

I am currently working on putting lst diffs in the revo bulks... Sorta budget way to get bulletproof diffs.

thats pretty much what i have concluded, and i have seen your post on the lst diffs, seems like a cheaper alternative to the RCM diffs. funny about the slipper, my last drive it started slipping excessively, when I brought the motor in i checked the temp and it was 200!!!! hopefully its not toast, ill check tomorrow, but the slipper was missing one of the pads when i looked...so guess thats an easy fix at least

edit: my slipper has been locked since i installed the new motor/esc and batteries, but ill try to loosen it so it actually works!

hey! I was thinking the exact same thing. I have a muggy, and when I replaced the stock plastic outer diff case with aluminium cases I noticed they'll probably fit in the revo bulkhead. Just don't feel like taking my revo apart right now. How far are you?

I am worried about the diffs in my erevo with the mmm combo. I loved the lst diffs(I could rum my elst2 50+mph and never had to worry about diffs or driveshafts! The diffs and driveshafts are my main concern with my erevo. I just want it to be as reliable as the lst2 was.

Well I got the mmm combo in my e-revo with low timing, low starting power,and 70% punch control! I ran 1 battery out and after 2 mins into the second set my brand new driveshafts broke! My slipper is pretty loose too. I need a set of driveshafts that will hold up and wear like my lst2 ones did. So how makes the toughest longest lasting cvds!

EDIT| I also have the extended rear arms!

[shizzon]

welcome to my world....1 run usually puts at least one driveshaft out of its misery, even if its brand new. Like i said before, i would easily pay big money for a virtually bullet-proof cvd and center drive-shaft set.

shizzon do you have durabilaty issues with the traxxas extended rear arms? Mine wont take a bad landing. I am on my 3rd set :( ! When they broke the landings were on one wheel but it wasnt that bad???
I am looking at getting the tekno extended rear arms to see if they will hold up better.

Also went threw another stinking driveshaft today. The other rear one doesnt look like its going to hold much longer. THIS STINKS! I wonder if the new summit cvds will hold up better since they were designed to take lots of torque at extream angles?

[shizzon]

I havn't had any issues breaking the extended wheelbase arms, though when i tried to move the pivot balls to th 10mm setting the arm cracked at the thread.yeah it might be worth giving those a try as mine break at the ends and that appears to be what is beefed up on the summit's axles.

[E-fanatic]

mine break at the ends too

Man 4 batteries down and 5 driveshafts gone. I am now at 90% punch control. This freakin blows. If the new BE e-revo comes with these driveshafts there is going to be alot of upset owners( I know I'm not happy at all) I just want something relieble and dont want to go threw 4 different brands to get it b/c I'm not rich!

Have you tried contacting Dan at Kershaw Designs yet. Even if he does not have what you need he can have custom stuff made up. It's worth a try.

To be honest with you I haven't...I am completely out of money unfortunately. Basically my girlfriend hasn't received her loans for school (it is the end of the term) because of a stupid issue where her SS# showed that she was deceased, and as far i I know they don't give loans to deal people. So anyways I have basically been paying for alot of her needs from my loans and i have run out unfortunately. perhaps after Christmas, or sometime next term, but as of right now im just trying to eat and get over this horrible throat infection that i have.

The BL edition has the new driveshafts like the Summitt will have. They should be an improvement over the current driveshafts. Are the extended rear arms swept back too far to run CVDs? A poorly-built drivetrain is the #1 reason I sold my BL Revo and got a Truggy (Losi Muggy, weak control arms but you can't kill the drivetrain).
