mydoddy69 Posted September 11, 2012 Share Posted September 11, 2012 So are there any success stories with the vapor pro esc? Because by the sounds of it folk have bought and paid good money for a rtr just to end up buying a sc8 esc??? Sent from my GT-I9100 using Tapatalk 2 I had mine from new right up till i sold it and the stock esc worked a treat.. Mind you if those dopes at HPI were to take a close look like i did they too my notice the problem is quite simple.. The stock ESC fan is pants and along with the fact the casing is a very tight fit allows no air flow hence no real cooling.. Results in them burning out .. Simple cheap and very affective way round the issue swap out the 25mm fan to a high air flow fan .. That's what i did and it was still going strong after around a 80 packs.. Mixture of 2s and 3s ..Made a huge difference and cheap as chips well almost Quote Link to comment Share on other sites More sharing options...
Rcmoore Posted September 11, 2012 Share Posted September 11, 2012 (edited) Mines been it bits loads, nearly every bearing has failed and needed replacing and ive had constant slipper problems, so it aint been plain sailing for me either same here, I have never had an rc this unreliable!!

Slugsie Posted September 11, 2012 Share Posted September 11, 2012 Here is my list of stuff that's failed: ESC - smoked on 2S Idler gear - stripped some teeth Diff bearings - at least one appears to have been broken from the factory Here is a list of what I have broken from bashing: Drive axles Front and rear uprights Shock ends Centre drive cups are getting quite worn and will need doing soon Overall I'm OK with the reliability of the XS, apart from the ESC. I've not seen anything whereby HPI have acknowledged an issue with it despite virtually every owner I've seen having them die. I think that considering the power this little truck has it stands up pretty well to abuse. Quote Link to comment Share on other sites More sharing options...
Rcmoore Posted September 11, 2012 Share Posted September 11, 2012 (edited) I have had fail: 2 rear diff bearings Standard esc 2 idler gears 1 drive gear 2 worn out diff input cup 1set of tranission cups And I have just received my centre rear drive shaft that is now worn out.

smash Posted September 11, 2012 Share Posted September 11, 2012 I don't like to see the lists of failed parts but I like not being alone in my wrenching, I lost a diff bearing and an input gear at the rhr bash, and one of my hr cvds failed although that was my fault for bodging a pin into it after it fell out the week before, I think we can all agree it's not the best kit reliability wise but I guess that's the trade off for whacking beefy electrics in small kits..

Bad-Co Posted September 11, 2012 Share Posted September 11, 2012 Got my returns number... Packing ESC off later. If it comes back fixed/replaced I'll try the bigger fan option or sell and replace option depending on what's more viable. Quote Link to comment Share on other sites More sharing options...
naymo Posted September 11, 2012 Share Posted September 11, 2012 High flow fan? Where and how much? Sent from my GT-I9100 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Matt B Posted September 11, 2012 Share Posted September 11, 2012 I'm getting mine replaced too, so I'll probably mod the fan and look at keeping it as a spare. Quote Link to comment Share on other sites More sharing options...
Rcmoore Posted September 12, 2012 Share Posted September 12, 2012 I have been using my castle sv2 in mine with a ansmann cooling fan and it works great! I put the 60 tooth idler in just to help keep the motor temps down. Quote Link to comment Share on other sites More sharing options...

Sent from my GT-I9100 using Tapatalk 2 This is the one i used you will need to mod the esc casing a little but well worth taking the time to do.. checkout my thread on here i'm sure its all in there (mydoddys xs) http://www.ebay.co.u...=item3f1b985aec Once you start using these fans then you like me will end up replacing all the ones you have there brilliant Edited September 12, 2012 by mydoddy69 Quote Link to comment Share on other sites More sharing options...
naymo Posted September 12, 2012 Share Posted September 12, 2012 (edited) Oooh looks like just what i need! Thanks! Just checked your other thread and it doesnt really mention how the fan was fit and pics not working for me.

mydoddy69 Posted September 13, 2012 Share Posted September 13, 2012 (edited) Ooops sorry pics been deleted .. as for fitting its easy .. remove the esc from the truck .. Remove the outer casing off the esc (four little tabs under sticker on the side).. remove the old fan test fit the new and trim where needed .. i used a little mesh on top just to stop all the crap going in the new fan .. put it all back together and job done .. Most annoying thing was rethreading the wire back in the rx box ..God i hate that box works great but a PITA or what Its been sold to darkangel so he might be able to post up some pics for you Edited September 13, 2012 by mydoddy69 Quote Link to comment Share on other sites More sharing options...

I must admit though, the stock motor is pretty amp hungry - it gives even my MMP a work out! Quote Link to comment Share on other sites More sharing options...

What it has now is a bit of grease ... I do not know, but it seems to me that yes, the crown and pinion are good, and touching. Because on the engine works fine ...

Bad-Co Posted September 14, 2012 Share Posted September 14, 2012 . Most annoying thing was rethreading the wire back in the rx box Take the rx box out and underneath are 2 tiny x head screws. Remove these and the rubber grommet can come out. One out you can squeeze it to open the hole up... Quote Link to comment Share on other sites More sharing options...
Slugsie Posted September 14, 2012 Share Posted September 14, 2012 Yup, or you could just take the rubber grommet out altogether. If you want to keep a degree of waterproofing then a wad of BluTak will work just as well but is soooooo much easier to use. Quote Link to comment Share on other sites More sharing options...
