Tugs take on the S5!

Thanks for keeping me involved in the process! There has been a lot of thought and discussion involved with this transformation, good to see your efforts rewarded and now revealed to the masses!

Certainly a solution to the inherent issue; having a company that will replace a poor motor choice for up to two years is ok, until the warranty runs out, hence why my S5 hasn't moved for months...

Bring on 2014 and conversions aplenty!

All the way through my motor shopping and testing, the CC ESC coped reasonably well. However, it was out of its depth (I know how it felt!  :xd: ), its fan was kicking in all too often! So before I killed it, I decided to look at other options. 

 

There's plenty of room under that big shell for a CC XL2, but I was trying (and failing miserably, 4 motors in about three months!  :36_11_13[1]: ) to keep to a sensible budget! So I tried the HW 150 Amp Pro from my Baja. This coped better than the CC unit, but was just to rough on throttle and brakes. So that came out and I went digging in my parts bin. 

 

In here I found an old MGM unit. It's a 14035-3 ESC from the E-series. That means 140 Amps continuous, 35 Volt limit! Yup, that's 8s! No, I won't be trying that! Having fitted that, the S5 was starting to take shape, then I crashed the bloody thing! Once again, a big thanks to Noj (this bit's hilarious!) for removing the bit I needed and posting it down to me. It's funny cos he disassembled the entire front end to remove it, not realizing that if you turn the car upside down, it's just four screws and the drag-link is out!  :xd:  Sorry bud, but that's funny! Anyway, a few more test runs have since followed and the MGM seems to be coping fine. No cogging to write home about, just a hint of stutter on start up. Temps are staying cool enough, which is a relief. 

 

I guess the point of this post is just to say "aim high", 150 Amp +! I may try my HW again, just to see if I needed to change some settings to get it running smoother, trouble is, with three kids, my test periods tend to be ten minutes at a time! 

 

I do intend on getting some decent video of this running, but there's not enough daylight in the week and the weekends are kinda busy!

 

Loving this rig, definitely a keeper! 

 

Latazz!

Cheers guys, I've really enjoyed toying with this car. I never thought a Savvy could be such a pleasure to work on, I actually look forward to it!

 

Another point just occurred to me, to remove the gearbox is a lot of screws, however, once you've fitted Dejans CD conversion, everything becomes more modular. Basically, remove a centre bone, then the battery boxes, ESC mount and undo the CD screws, then the entire CD mount c/w motor just slide out! So simple! Nice design work by Dejan! The TVPs stay in place! Bonus!


Yup...I did that silly thing..good lesson in how to get the front end off tho!!

 

 

I still don't know how to do that!  :xd:


Very nice post fella, well explained and things, I think the Sirius or Castle would be the way I'd go motor wise.

Look forward to your next post about ESCs :) that was a good read.

 

 

Cheers, it's been a lot of fun!

Couple of pics of the MGM and fan being installed.

And a speed run, just can't remember what voltage this was on, sorry.

Dry weather, daylight, free time and I will get some video of it.

I've been tidying up the cabling.

It's far better than it was, the pics don't really do it justice.

I've actually turned the ESC mount around 180 degrees. This moves the switch to the back, not a problem. I had to move a chassis brace, but not far enough to be an issue, so I'm not concerned about loading.

Cheers.

I'm really quite impressed with these figures! Shall we up the voltage?  :whistling:

I've been waiting for this thread :D

Top work sir, ill have to try the GPS app on my toxic monster:)

Up the voltage please :lol: and video it.

Would've videoed it tonight, but was already dark when I started testing. I'll get onto it ASAP.

For sure up she goes

I bet you say that to all the boys!?
