Cat SX LiPo
 

Does the lipo car have slots under neath the cells or is it flat carbon?

My lipos has notches on the bottom to locate into slots!!

Paul

The lipo chassis is flat carbon and has two slots in but they provide two cf slot locators to glue onto the flat side of a Lipo. Unfortunately is seems that they have not catered for the packs (Reedy) which already have location bumps on for locating in existing cell slots.

Dremel! :woot:

Couldn't you turn the Lipo over ?:)

Thanks guys will have to come up with a solution to that, i think dremel sounds a good one!!

Paul

Really :(

not to that car, i will sand of the humps on my lipos then stick the carbon bits too them!!

Paul

Can you get the bits of CF you stick to the LIPO as a spare part - I'm assuming most people have more than one pack and I can't see the part listed on their website?

I haven't got the manual with me now, but have a look on the exploded diagram - that usually shows a lot of stuff like this. :thumbsup:

I cannot see the part number in my manual other than the Lipo chassis part numbers. I have also looked at the Schumacher parts list on the website and cannot see anything listed that would match these small parts.

I assume that they are using the ones that they first brought out for the Mi3 - part number U3271 - Lipo Locators - £2.99 per pair (in stock if anyone needs some)

They are available, becuase i know people that have been using them in Mi3's for quite some time. I need to find part number as well, because i've lost the ones i had!

Ooops....... beat you to it Matt

You've saved me looking for Part No :D:thumbsup:

Or for lipo packs with the 6cell locations lugs on the bottom you could make a new battery bar and stop the lateral movement like this http://i266.photobucket.com/albums/i...50908_1757.jpg

:thumbsup:

Si, your a ledgend dude. That was something I was planning to do - you beat me to it, so I am keen to physically see your car. :thumbsup:

What pinions would you be running with a 5.5 or 6.5?

The reason I ask is that, when I have the core lipo in the car, it stops the motor from moving forwards, so you would only be able to fit a small pinion on by the looks of it.

Ill be playing with it on Sunday although with care as i haven`t place an order for some spares yet.:D

Chris Long is running a 23t pinion with a 83t spur on a Novak 5.5R motor.

Sly, where did u get the batt holders??? that wld be really useful

From the carbon srcap bin of a large aircraft builder and made it at home.
4mm and 8mm carbon used.;)

Thats a nice piece of kit..

For those less skilled (ie. me) I just drilled and put 4 countersunk screws through the chassis to a 1mm washer and m3 nut on the outer of the chassis and 2/3mm washer and m3 nut in the inner of the chassis to locate the lipo - 2 on each side (i had trouble glueing the lipo locators to my trakpower lipo).

Mossy made a lipo strap using an extra post and r clip .. it can be seen on the worksop report.

It was an interesting experience watching you glueing your lipo into the car james...with lots of swearing!:lol:

....especially when it looked as though you'd glued the lipo to the chassis!:thumbsup:

I think an easier way to use the lipo locators, would be to get the lipo in position with the car upside down, then use a marker pen to draw where the locators need to be, then take the lipo out of the car and glue them away from the chassis. I did the same as james and almost glued mine to the chassis too.

Admittedly I haven't seen the Cat chassis layout, but rather than glue why can't you put the locators in position on the chassis, put double sided sticky on them and then lower the battery onto them, so everything is correct but double sided is a little easier to remove!!

Alternatively, wat i can think of, is to use velcro straps n lay it along the length of the lipo. And the other side of the velcro on the chassis. U can even apply velcro straps on the top of the lipo n the underside of the batt bar. May not be the best way of securing but imo, beta than gluing locators.

i also think smokin's method works well too, at the expense of the chassis

I think I'm going to go down the velcro route next time.

You can use double sided tape, I would imagine it would work just as well.
I had to build it as per kit instructions for review purposes, thats why I used the glue method.:)

since u mentioned its for review purposes, perhaps this glue-velcro-batt bar mod thingy can be part of your review. Im sure potential sx owners will better appreciate this method more than anything else, of coz unless they are only running one car or have loads of lipos to spare. Just my thoughts....;)

I've got the Lipo Version. What Spares/Hop-ups would you recomend to get. Not many shops have any spares in at the moment.

Isn't that how every does them!? :confused: :D

I have velcro on the under side of the battery strap too.

Admittedly, I glued the locators to the sticker on the lipo first time round but hey ho, no surprise they came off. They are now epoxied to the plastic case. Will see if it holds up better.

I like the idea of the screws though, seems a good strong permanent solution. :thumbsup:

Just thought i would post some of mineAttachment 4014

At worksop I just used a strip of velcro on the top of the lipo and underneath the battery strap. Had no problems at all. The cell didnt move at all and if anyone saw when my car was cartwheeling down the straight at full speed and I think hit Jimmy at the end of the straight will know it was well tested!!!!!!:woot::woot::woot:

I did a cart wheel down the straight with mine and my servo came off its mount :( Will have look into the mounting method again.

Got my car yesterday, all ive got to do is build the shocks when i get my whities, spray the body and install electrics

other than some user errors car goes together loverly!! cant wait to run it!!

For some of us who want to use Team Orion carbon edition/Tekin/LRP Competition car line LiPo sticks, I was thinking about this kind of LiPo tray:

It will just require to drill an extra hole on the CF chassis nearby the front bulkhead.

It could be made of CF or plastic sheet...

I may be interested in one of them, are you goign to make them?

How thick would they be?

Paul

Could be possible ;)

The only LiPo stick sample I have in hand is the Intellect 3800mAh 25C:

I started to get dimension on it and it leads to a thick of 1.8mm.

Could someone tell me the dimensions on a LRP LiPo Competition Car Line

I need the wide between 2 embosses and the depth of them :thumbsup:

This version could be better to fit LRP LiPo :)

I think LRP one should fit in without anything extra - should be fine with the humps facing upwards.

I made a prototype part according the last drawing. I used a very flexible plastic sheet and cut it with Dremel. The oblong holes allow to tune side position by 4mm:
