RoddersUK Posted February 11, 2019 Share Posted February 11, 2019 Hi all, I bought a second hand e-revo brushless. 1 year old, been running 6s, 68/22 gears. Replaced one half of a driveshaft in that time. I run it today, 5 seconds, snap. A rear one broke. Is this just because its old, or because they are no good. I was running it on tarmac, nowhere near full throttle. So do I replace with plastic and off I go for a few months.....or do I get metal.........? if so, which metal ones, I've read some are worse than the plastic ones?

You generally get what you pay for, steel shafts will hold up much better. Tarmac is a very high grip surface with barely any wheel spin so it's not surprising the plastic shafts snapped.

Tug Posted February 11, 2019 Share Posted February 11, 2019 V1 or V2? The diffs in the V2 are better, but not bullet proof. My point is that plastic shafts absorb more shock, thus protecting the diffs a little. The trouble with running 6S is the plastic shafts struggle to handle the torque. The Traxxas steel CVDs aren't bad, but not perfect either. There are probably more options out there, but I'm not up to date these days. On my V1, I've been happy to run plastic shafts, they're easy to change and handle 4S quite well, but not 6S. Quote Link to comment Share on other sites More sharing options...
Tug Posted February 11, 2019 Share Posted February 11, 2019 I used to bulk buy from Jenny's RC, so always had spares with me. Quote Link to comment Share on other sites More sharing options...
RoddersUK Posted February 11, 2019 Author Share Posted February 11, 2019 (edited) It's the V1. I'll have to stick to 4s on the tarmac then. Ordered some plastic for now as don't wanna spend on the wrong thing to make it stronger, I'll research more and make sure.

RevoMikey Posted February 12, 2019 Share Posted February 12, 2019 The summit shafts hold up much better than stock. Minor alterations but much much stronger The traxxas's cvds are junk, you want to change the arms to rpm and fit summit shafts. End of the problem.

RoddersUK Posted February 13, 2019 Author Share Posted February 13, 2019 (edited) OK, that sounds good revomikey, I shall look into it. The centre front broke yesterday, don't think these things like tarmac. Bought traxxas metal ones, hope these are ok? Can you point me in the right direction for arms/shafts I need? are you saying metal or plastic summit shafts?

Tug Posted February 13, 2019 Share Posted February 13, 2019 I never liked the Summit shafts, didn't seem worth the extra cost for not much extra lifespan. I've never broken a front centre, but I don't run 6S. Quote Link to comment Share on other sites More sharing options...

RoddersUK Posted February 13, 2019 Author Share Posted February 13, 2019 To be fair, I did reverse then go forward too soon. I think that gave it a good go at breaking it! Quote Link to comment Share on other sites More sharing options...
RevoMikey Posted February 14, 2019 Share Posted February 14, 2019 The metals shafts bend with rpm arms, avoid that combo if you jumpAlso, check your PM'sLatersSent from my P9000 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Tug Posted February 15, 2019 Share Posted February 15, 2019 I've used the steel centres, didn't last long. However, I've never replaced a stock plastic centre. Quote Link to comment Share on other sites More sharing options...
