Another LST XXL Conversion

[Mozzy]

Yes, sure does.

As I said, it was your choice & just some numbers thrown in from me.

yeh no worries.

I am wanting to go with the 1717 as it has a lower kv than 1700 and this'll mean that the perfect pinion is not the smallest.

Also the XXL is a big car and still weights a heap more than my ERBE so i want to go with a 1717. Plus i have it lying around so why not use it.

Did you get it cheap from CC like me?

I actually bought a few motors that were heavily discounted, plus a few 1/10 packs & motors.

No actually,

I bought a 1518 and 1520 from CC during the sale but i bought the 1717 about a week before the sale and paid $220'ish.

EDIT: I have ordered a slipperential for this and will be running a 52T spur and about 30~50K fluid.

Just finished doing the CAD for the lower plates. All i have to do now is make the lower plates and also make the motor mount.

Here's my idea for making the plates.

I did the CAD in scale so i printed out the plates and i'll glue them onto the alu. I'll then punch the holes and cut the overall shape. I'll then drill all the holes and everything. One thing though is i need more M4 CS screws and some lock nuts for them. I think i need about 10 screws and nuts.

i should have some pics soon.

Where did you get your carbon fiber from? What kind of dremel bit did you use to cut it?

I got my CF from carbonfiber.com.au (in australia).

I am using a carbide cutting bit in my dremel for the CF or just a cutting wheel. For the alu i either use a cutting wheel or a milling bit (i think??)

Yeah, I've been toying with the idea of making my own carbon fiber chassis and plates when I get my XXL.

Was it hard to cut? Did it split? Did you seal the edges of the CF wiht super glue?

I haven't driven my XXL much to be honest. It's just been too wet and i don't want to get all my elecs wet.

The way i had it set up before i wouldn't think the CF would split.

The CF was easy to cut but i used a jigsaw for most of it.

Yeh i sealed the CF with super glue. What i did was run a bead of glue on the edge and leave it for about 10 seconds then wipe it off. I also did this for the screw holes by doing a similar thing.

Do you think the 2.5mm will be thick enough? If I measured correctly the stock XXL chassis is 3.5mm

Hey,

I just measured the chassis and it's 2.5mm thick. It may actually be 2.54mm as that's 1/10" and well losi have this weird fascination with the imperial measurement system.

[KaztheMinotaur]

Those silly Americans and their imperial measuring system...

Well thats good then...I think Hobby City has 2.5mm CF.

Well i made some of the lower plates and it is becoming a little difficult for a few reasons. Also they didn't turn out well.

I am now thinking of just sending off the CAD to the place where i got my CF from as they do CNC cutting.

Hopefully it won't cost too much.

Hobby city has carbon fiber??! Link please because i dont see any??!?

Well i haven't made an update for a while and here's the progress.

I remade the lower plates. I now have everything ready to cut the alu angle to make my motor mount out of.

To mount the battery trays this time i have tapped the lower plate so that there is no need for a nut (8) on every mounting screw.

Also i recieved my other LST XXL. and i have installed a TD racing motor mount. This Car will have a 1717 motor and maybe 6s.

In my project LST i am running a MMMXL esc as it allows me to do heaps of stuff i couldn't before.

Hopefully this made sense as i am tired and i'm not sure what i am actually saying.
