VulcanAndy89 Posted March 22, 2013 Share Posted March 22, 2013 Hi, I'm looking to add a jconcepts overtray to my Slash 4x4. After reading some writeups on it, it looks like I need to add some form of cooling for the electrics. Can anyone give me any advice on how to go about this please? Cheers - Andy Quote Link to comment Share on other sites More sharing options...

Didski Posted March 23, 2013 Share Posted March 23, 2013 I got what Chris has suggested but found the motor still running hot with the bigger Lipo so I added a turnigy heatsink with fan too. Temps really good now, my telemetry doesn't show it getting half as hot as before. Quote Link to comment Share on other sites More sharing options...
VulcanAndy89 Posted March 23, 2013 Author Share Posted March 23, 2013 Thanks for the advice guys, that Velineon accessory fan looks good, and easy to fit. I'm still running Nimh batteries. It looks like the overtray itself can be modified with some vent holes and a second cooling fan running off a 9V battery after doing some research. Talking of the overtray, I've also been searching the net and am having difficulty finding one for sale in the UK. Would anyone have any advice on how to track one down, or will I have to order from the US? Quote Link to comment Share on other sites More sharing options...
Noj Posted March 24, 2013 Share Posted March 24, 2013 Fit the undertray instead, allows plenty of air flow and keeps most of the clart out. Alternatively, try an Outwears cover, which are breathable fabric. Coupled with a fan, should see you right. Quote Link to comment Share on other sites More sharing options...
VulcanAndy89 Posted March 24, 2013 Author Share Posted March 24, 2013 Update: after a lot of persistence I have found a UK website that stocks the Jconcepts overtray, happy days! Time for some phone calls later in the week methinks. I considered the undertray Noj, but I watched a review of it on a Slash 4x4 and it just acted like a scoop, collecting a lot of debris inside the chassis. I've just ordered a 70mm cooling fan off the net and I may order the Velineon fan for the ESC later on, so I've started the ball rolling. I plan to mount the 70mm directly under the louvers in the overtray, which I will cut holes in. I'm going to use a 9V PP3 for power and I will mount that in the overtray as well. I've seen a video of this setup and it seems to work well. I'll get back to you all on this once I have it sorted. Quote Link to comment Share on other sites More sharing options...
