fletch101 Posted December 15, 2015 Share Posted December 15, 2015 Hey everyone. First time straying into the rally section. One me mates wants his car converting too electric It's an old hpi rally car with Scooby body1/10 Think I'm going for a 80 amp turnigy combo from hobby king as he's on bit of budget and I use turnigy on my hyper st and it's got bags of power. What kv do people reconmend and what kind of pinion teeth do people reconmend Thanks Quote Link to comment Share on other sites More sharing options...
TMaxxDave Posted December 17, 2015 Share Posted December 17, 2015 Anything from 3000kv to 4500kv IMO, I'm not sure what size the spur gear is on this car so can't suggest a pinion Sent from my iPad Air using Tapatalk Quote Link to comment Share on other sites More sharing options...

fletch101 Posted December 26, 2015 Author Share Posted December 26, 2015 This is all complete hobbyking 80 amp turnigy combo and about 3200kv motor running 15 tooth pinion (I guessed. Maybe gonna try a slightly bigger pinnion . Its not short on power on 2 cell lipo's Quote Link to comment Share on other sites More sharing options...
fletch101 Posted December 26, 2015 Author Share Posted December 26, 2015 (edited) Scratch made battery box and scratch made motor mount. I refitted rollover bar right at back to run the motor wires over the top and keep them secure pluss i thoguht it made the car look more standard Just so you all know. It was made for practicing with milling machine and not just buying parts and help too keep costs down. Motor mount was made with a large degree of adjustment for different pinnion combos Edited December 26, 2015 by fletch101 Quote Link to comment Share on other sites More sharing options...
Thedrum2010 Posted December 27, 2015 Share Posted December 27, 2015 That's different ! Couldn't you relocate the esc, get rid of the old battery and receiver box and mount the battery there ? Quote Link to comment Share on other sites More sharing options...
fletch101 Posted December 27, 2015 Author Share Posted December 27, 2015 I was wanting too keep much standard as possible for now. He'll be wanting controller and receiver soon as they are old crystal type. Pluss i suspect the servo won't last long as the throttle servo broke while I was standing. Me thinks when I change them I might re arange. The esc is double sided taped down and the trimmed out original battery tray is a hollow shell pinning esc down and as bit of a splash guard( motor and esc are waterproof anyways ) If I was putting battery on other side. I'd have too alter servo location too I should point out the body sticks out past the wheels anyways so although the battery sticks past the chassis it's not very bad Quote Link to comment Share on other sites More sharing options...

You don't need one now Also, if the esc is waterproof, that's even more reason to get rid of the receiver/battery box ! Quote Link to comment Share on other sites More sharing options...
fletch101 Posted December 27, 2015 Author Share Posted December 27, 2015 Just little bit of added protection as the lad wanted to try and keep the hpi logo is I could Quote Link to comment Share on other sites More sharing options...
Tamiyacowboy Posted December 29, 2015 Share Posted December 29, 2015 some help and advice on your conversion. with your motor and batery on the same side your putting a lot of lean into that chassis, so its going to feel a bit weird. if you look at your machine from above the whole left side is filled with an esc-rx and a servo right up the front. behind the motor is a nice area to house the esc, just intront of the motor a huge space to allow for your rx and or esc. where you removed the esc and rx is a nice space you could now mount that battery box to , your motor +esc+rx will be a small amount less in weight but will balance that chassis out alot more. it also means your able to keep the battery more inside chassis have a look car facing forwards you at rear, rear left side is packed with all the rubbish stuff taking up space . motor is center mounted so forces battery out into the side skirt of body. if we remove that plastic covering and esc-rx we can slip your battery here maybe ? , then we can shift the esc to behind motor, and the rx up in the front of the motor side. a more refined layout allowing for a more balanced chassis and maybe even bigger battery packs 3s on its side instead of lay flat.

fletch101 Posted December 29, 2015 Author Share Posted December 29, 2015 Thanks I was worried about the weight on one side but after trying. It does sit level and handel well. I didn't want to spend vast amount of time on it to find out me mate wasn't going too keep it for long. Letting him have a good bash with it then letting him make his mind up after a while. If he wants too keep then I will do a re arange with better layout I was stuck for time too get it done and back for him. Limited work time on it. Pluss does anyone know what Base the chassis is as I only know it's a hpi and old lol Quote Link to comment Share on other sites More sharing options...
fletch101 Posted December 29, 2015 Author Share Posted December 29, 2015 I was going to put battery on the left but would mean messing with the servo mounting and mounting the reciever . He's getting a fly sky reciever soon so thought best do the whole rearrange at once. Only 2 clips hold the whole left side of things onto the chassis. So is easy too clean too Quote Link to comment Share on other sites More sharing options...
Tamiyacowboy Posted January 1, 2016 Share Posted January 1, 2016 HPI RS4 to what i make out. it could be the HPI super nitro RS4 as they did come in the rally model fitted with scooby shells to. so its either a stock rs4 nitro or a super rs4 nitro Quote Link to comment Share on other sites More sharing options...
