X6 lipo retention
 

What method are you guys using to retain lipo packs? I've seen various methods, with the best being the custom brace using by Kinwald. He should produce this under the DDP brand. I'm sure they would be popular!

The easiest way to hold in a Lipo in an X - 6 is to flip over the stock battery brace. Check out the pic here to see what I mean: http://www.2wdrc.com/images/TechImag...iPo_02-big.jpg

The way to mount the battery with a CF piece is to drill and tap some holes down into the 4 ejector pin pads located around the 4-cell area. You can roughly see those locations in the pic of BK's car above. I have a CF brace like this and just hold it in with four long screws/washers, screwed down through the CF and into the chassis. Brian has a system a little neater and more secure than that; he mounted some Lunsford quick-change shock mounts into the ejector pads, spaced up so the CF brace had something flat to rest on, and then used the AE thumb nuts to hold the brace on.

Thanks Paul.

I have to mount my speedy (Speedpassion GT) in the 2-cell position since it is slightly too big to fit in the side pod. This mean flipping the brace will not work.

Regarding the servo brace, I notice Brian runs without it. What's your opinion on this? The chassis does seem very stiff so I am also considering leaving the brace off too and using AE FT servo mounts.

Cheers,

Scotty,

This is how I run mine for stick pack Lipo. I too now run the speedo in the middle (much neater and better weight distribution), it looks quality.

I've cut the brace just in front of the little ridge that holds tha pack, however I've also folded a peice of lexan over so that it really holds tha pack in well.

Lastly I don't run the front brace now either. The chassis is very stiff in that area and now I don't need the servo mount or battery strap mount it's neater to mount the PT up there.

That looks really tidy Dan, i'm going now to get the dremel out:thumbsup:

Yes, very neat indeed Dan. Have you dremelled the battery slots down so the lipo sits down lower on the chassis?

Ben

I have read in another thread not to do that as the chassi wont be as stiff Ben.

But it looks like he has in the picture. Is that a azurashi front wing I can see and what is the velcro for in the battery tray. Looks bloody good Dan.

Velcro to hold the lipo in place and yes thats the azarashi front wing, if you dremel th cell slots it could make the chassis a little more flexible but nothing major I don't think, in all honesty I don't think theres any need to do that as the car will already be very well balanced

Running without the servo cover should be fine, Scott. Its not really much of a brace, but rather a hold-the-servo-in/mount-the-battery-strap/mount-the-transponder piece.

For the others, those little vertical braces are still there in the pics. Look closer; if they weren't there you'd see dremel-marks from the process of removing them.

And you'd be surprised what those little braces do for the chassis stiffness. The outside walls look stiff (and nice and tall) but they like to bow outwards because they're straight along there. I really don't recommend removing the little braces. Also, those little braces make excellent little areas to put lead weights when your car is too light because of the lipo.

Also, Lipo + speed control in center = ace :thumbsup:

....... have you been following some sort of UK integration class, or does Dan have your login code ?? :woot:

OK,

Spence, Yes it is an Azarashi front wing, they are proper good. Thicker that the J concepts or Proline ones and you don't have to screw it to the tower, it's held on by the shock top screw. Thoroughly recomended!

I've not dremelled down the slots underneath the cells. They do add stiffness and becasue the Lipo is lighter some extra weight transfer probably isn't a bad thing. I have dremelled out the centre one in the 2 cell box. Personally I don't think this adds much stiffness because the 'box' that surrounds the 2 cells is 3 times taller and so it's I beam value will be much much higher (Paul do you want to work that out??? ;) ). I've mounted a peice of lexan the exact size of the box so it's stuck down on either side and down the middle.

I've only tried 1 lipo so far which was a 5000mah ish one i.e. one of the heavy ones. It was clear it moved the weight balance to the back a bit, I eventually ended up adding 40g of weight to the front to get the balance back with no other setup changes. Ellis has done some calcs and says that 40g is about right for a very heavy pack. However the normal 3200 - 3800mah packs are lighter to the point the weight balance is very similair to where the car used to be with Nimh, but obviously MUCH lighter, likely not too much over the minimum wight limit on mini spikes, possibly even under the limit!!!

All is VERY good running an X6 with Lipo!!! :D

Thanks Dan. Looks like a good method for the batt pack. I'll do same. Nice layout too. Very clean.

Cheers,
Scott

i designed my own carbon lipo strap - it mounts on 4x steel hex posts screwed through holes drilled on the ejector 'pads' and uses stainless thumb-nuts to hold the whole thing down. couldn't resist putting the x-6 logo on it either !!:D:D

also made some carbon plates to fit into the now redundant forward battery locations for the brushless esc

Here is my simple version of lipo battery plate using the original rear post and some old turnbuckles (see the plastic nut).
Two cell vertical braces removed to fit the ESC and little holes dremeled in the horizontal ones to pass the sensor wire below the lipo.
Ready to test and planing to cut new plates in CF.

Regards,

Isn't the word 'retention' just top draw? :woot:

Agreed G, it just adds a bit of class to the XFactory section that others seem to lack :thumbsup:

Hi all,
any more suggestion about the battery strap? i just want to run using lipo only, Kinwald's one looks really cool~

How about the battery strap from the X60 truck, that fits and I think the spares and kits are on the way to the Uk. Get in touch with Dms they will sort you out!

can the motor wires not be run under the lipo like the Sensor wire is on 'chemax92's' car? Might make it a little neater if they fit :)

I can tell you for sure the X - 60 strap will not fit on an X - 6. The way the strap is mounted just wouldn't work on the buggy - the strap doesn't have material over where you could bolt it down, and it does have extra material that would get in the way of other stuff.

I think it's a shame that nobody produces this strap (X factory should come with 1 very soon). :thumbdown:

I find it a bit amateuristic that you can run the car with lipo but you can not buy a descent strap for it.

You can run the existing strap, just if you want to put the esc into the central square instead of the two cells, then the strap fouls the esc, its up to you.

As far as I know, the X - 6 was the first car anywhere to come standard with a battery strap that works with LiPo. The reason why the X - 6 strap looks the way it does is that we made it fit both cells and LiPo. As far as I know, we are the only car that accomodate both so easily.

Therefore, I think shots at us for "amateruistic" are quite harsh indeed.

With the X - 60 we are again breaking new ground: The 60 has been designed entirely around LiPo, with cells an afterthought, instead of the other way 'round. Drivers who wish to run cells in thier 60s will actually have to purchase a different battery strap as a separate part.

When the truck is finally out (It is just taking forever...) we'll see what we can do to make the X - 6 work bertter with LiPo. One thing at a time!

That's completely uncalled for. The kit X-6 strap works just fine to hold the Lipo in, I've been using mine like that for ages.

Have you read post #4 on this thread??? :confused:

Just a little rant.

Seems I had a bad day yesterday. :blush:

I apoligise!

i should have some news very soon regarding the availabilty of my carbon lipo strap conversion kit. it will have all the parts needed to convert your x-6 to hold most common lipo packs and have some carbon infill pieces to allow you to fit the esc in the middle of the chassis:thumbsup:

keep watching !!

Strap Issues?
 

:thumbsup::thumbsup:The car works perfectly with the kit strap for cells or lipo. Its the easiest car to swap one to the other on the market. Peeps only have any probs if they move the speedo to the middle. If you use the normal kit positions for the electrics its perfect. I love mine to bits and dont see what the fuss is about. It suits all my lipos and handles brilliantly. Keep up the amazing work X-Factory.

but with the lipo's in, and the ESC in the middle, you really can start to balance the car just as you want to...plus, with the ESC in the middle, the wires can be kept as short as possible and the chances of it getting any moisture on it during the UK summer season is reduced even further.

So it's all good.

Nick, any news on your übercool brace? :)

I have some lipo specific carbon straps in the works... prototypes will be made very soon in silver carbon;) :drool::wub, the designs are finalised and finished on cad just waiting for a reply from the company that will be cutting the parts for me :) there will also be a line other parts perhaps available for the X6 that I've been busy with for the past month. When I have them I'll post it all up and if there's enough interest (10 people or more atleast) I will have a batch made from the black carbon weave that is more favoured :D

Cool! As to mods & prototypes, there's 2 good options as I see it:

1) Sell it via a dealer with an international webstore. "Someone" then has to coordinate production and distribution.

2) Place the CAD's with for instance Fibre Lyte so anyone who likes can order their own copy. If you order for instance the tower braces for XX4/X-5 you can actually ask to get Dan Greenwods version.

Good luck! Looking forward to see the stuff!

It's GreenwoOd ;)

I now recomend X Factory Shock Tower brace :)

Shit! I'm so sorry Dan The Man! :D

Have a great weekend guys!
