Brushless J-truggy

Jasper. Seeing as you live in Holland, have a word with Mike and see if he can get the 13XL shipped direct from bk's factory in Germany. I live in the UK and Mike got my system shipped direct from bk. Just an idea......

[Serum]

Yeah, he knows..

[maxxdude1234]

cool, just checking :)

[Jasper]

I know maxxdude :)

I added one hole at each side of the chassis for the cells. I extended the chassis because the axles doesn't didn't seem to fit. I use savage axles for the f/c and r/c diff. The length of the chassis is now 494. That is huge man! Is it no to huge?

The upperdeck is completely changed. I made a new design. I added two holes for the savage steering and I made some space for the motor behind the motormount.

Now I need to design the shocktowers. I try to finish that this weekend because monday my friends vacation is over and the is going to school. So he can cut my design out :)

Let me know what you think of the new design!

it looks good Jasper

Looking good!
How thick of alum. are you going to use for the chassis?
Have you figured how you're going to secure your battery packs?

A couple suggestions:
Add a milled slot to each end and on each side of the battery locations, in case you decide to use web straps to secure them. Easier for your buddy to mill them in (even if you never use them) than to want them later and not have them.

If you're going to use rigid straps mounted on posts, drilling holes is no big deal - slots aren't as easy!

Might also suggest making the chassis out of thicker stock (perhaps 5 or 6mm) and plan on milling down the majority of it to perhaps 3 or 4mm. I.e., leave a 3 or 4mm wide "lip" all around, for increased rigidity. Leave chassis full thickness over mounting points.
Easy for your buddy to do, if he's using CNC milling equipment - and will leave folk's jaws on the floor when they see the finished product! :004:

good luck and take lots of pics!

Thanks boss and Cadtech.

Cadtech, I allready figured out how to secure the batteries. I will use the parts from my xray evo2.

I only need to design a battery strap that fits over my 10 cell slots. And I allready did that :)

Good thing that you mentioned the thickness of the chassis. I think I will go indeed 5mm. Milling some places down to 3 or 4mm seems to me not like a good idea, because there are allready so many holes in the chassis. I really need a strong chassis for the BL power.

Here is a screen shot with battery straps and shocktowers mounted:

The battery straps and shock towers both look good imo.

I made some progress with the parts for the truggy. I ordered different stuff from ebay, at my local hobby shop and by BKelectronics. Mike, I am sorry that I didn't placed the order by you. But it is cheaper to boy it from different stores. And I also don't have to pay tax.

But here are the parts.

- Pro-line crowd pleazer 2.0 monstertruck
- Pro-line white wing
- Venom speed meter
- 4 ofna 9.5 rear shocks
- BMS 630MG servo
- BK wanderer 12XL
- 15,16,18,20 tooth 5mm bore pinion

Today the BK wanderer 12XL came in. I thought the wanderers had only better bearings, were blue and had 5,5mm connectors. But this motor has good more! Build in heatsink, flat grinded shaft for the pinion. And it looks cool! Is this the new version or something?

I brought my design to my friend and he is now working on it. It is done in one or two weeks.

Cool!!

i'm getting one too!! ;)

That motor looks awsome. Looks a bit like a 540c XL, and by the looks of things the endbell is removeable.

Thanks guys. I really like this motor :027:

I want to know how the motor will handle 16, GP3300 cells. So I placed the motor in my 1/8 buggy. The gearing was 46/12. I also added a wing mount and mounted the ofna 9.5 springs at the rear.

This motor ROCKS :017: The torque of this motor is massive. I drove the buggy for at least 20 minutes hard. Straight on the road in front of my house and on the grass. After 20 minutes the batterys were still full! And the power was almost the same than at the beginning. Then a couple of friends dropped by so I talked and drove a little bit. But not so hard. Then I helped a friend to walk his commercial papers. So I drove for one hour in the neighboorhoud with the truck. But very slowly.

So after 90 the minutes the battery's were empty! With 20 minutes hard driving and the other 70 slow/mid. This is very impressive!

The motor was getting less than hand-warm. So I can gear higher. I am going to buy some IB3800. Then the run time and the speed will be sick :017:

De-anno that heatsink and it will be even cooler.

Nice conversion Jasper.

[crazyjr]

thats cool, I wondered about those motors
