stickyr6 Posted May 6, 2014 Share Posted May 6, 2014 I really didn't want my first post to be a negative one but hey ho, So I bought my Slash 4x4 on here off a top lad (samdzharov) running all standard gearing and Lipo 2s, After a few good bashes with no issues I decided to up grade to 3s so bought a Turnigy Zippy 5000mah 3s 11.1v 30-40c hard case battery, First run out today lasted 15 mins and the car stopped, Motor and ESC was hot, ESC has a fan on it but clearly not cooling it enough, so I let the car sit a cool a while, next thing thick black smoke came from under the ESC, I unplugged the battery and it stopped.. Gutted!!! So I'm at a loss now, have both ESC and motor burnt out? Was putting the 3s' to much for the VXL-3s system? Do I buy new or try and send off to TRAXXAS? If I buy new again do I go back to 2s? I run with friends who have Hyper 7's so I just wanted my Slash to keep up with them, sorry for all the questions, would just like to be pointed in the right direction and to see where i went wrong. Thanks.. Chris! Quote Link to comment Share on other sites More sharing options...
stretch Posted May 6, 2014 Share Posted May 6, 2014 3s is pot luck on the vxl system, as you bought second hand it won't be covered under warranty, i recommend upgrading to a hobbywing sc8 combo. 2 Quote Link to comment Share on other sites More sharing options...
mini-z-awd Posted May 6, 2014 Share Posted May 6, 2014 like stretch has said sc8 combo or just the sc8 and a different motor. may mate runs a sc8 wp esc and tenshock 5200kv motor and that thing fly`s along and if you go 3s again drop the pinion sizer atleast two teeth as that was why both got hot 1 Quote Link to comment Share on other sites More sharing options...
stickyr6 Posted May 6, 2014 Author Share Posted May 6, 2014 Thanks for quick response.. So if I went for the hobby wing combo it bolts straight in with similar performance? Off the top of my head it has a 13 tooth pinion so look for 11 0r less? Quote Link to comment Share on other sites More sharing options...
Bigjimknickers Posted May 6, 2014 Share Posted May 6, 2014 I've just bought a slash platinum & I'm expecting to fry the esc & motor tbh, then I'll go hobbywing wp sc8 & motor. Have that same combo in my lads savage xs & its been fantastic. 1 Quote Link to comment Share on other sites More sharing options...

Tug Posted May 6, 2014 Share Posted May 6, 2014 You'll want to consider MIP CVDs for your Slash, at least at the rear. They add weight, but 3s will destroy the stock CVDs. 1 Quote Link to comment Share on other sites More sharing options...
stickyr6 Posted May 6, 2014 Author Share Posted May 6, 2014 Is this the kind of package that would work? http://www.ebay.co.uk/itm/360800461787 Good shout about the. MIP CVD's, I'll order some of them also! Thankyou! Quote Link to comment Share on other sites More sharing options...

Alex97 Posted May 6, 2014 Share Posted May 6, 2014 No, they had a connector on the end that as now been cut off. They were used in my st4 and how it was wired they were just the right length. They are Quote Link to comment Share on other sites More sharing options...
Didski Posted May 6, 2014 Share Posted May 6, 2014 I've had my slash 2 years and still on the original vel spec - I changed the pinion to 16 and temps been good on 3s. I was expecting it to go, but it keeps on going... The combo recommended was what I heard everyone saying so would be my choice, it must be a trusted replacement. 1 Quote Link to comment Share on other sites More sharing options...
DazzaClio Posted May 7, 2014 Share Posted May 7, 2014 That's unlucky with the Vxl-3s esc but as you bought it second hand you don't know what previous use etc it had. It's just luck with them tbh I've had some like Didski which have lasted for a good year on 2s and 3s with no problems, then others which have just packed up right from the start. Going for one of the Wp Sc8 combos is a good upgrade over the standard system. If you haven't already you should defo invest in a temperture gun so you can monitor your temps more accurately and get the gearing correct. Good luck. Thanks. 1 Quote Link to comment Share on other sites More sharing options...
