Attractive assembly of LED.
Being a noob in electricity, I personally put these: http://www.hobbyking.com/hobbyking/s...dProduct=17189 ...who enter perfectly in the genuine pods.
Only defect, we cannot re-clip the small plastic bars.
For the rear, I have those orders it: http://www.hobbyking.com/hobbyking/s...Strip_RED.html

I did't expect in much with these HK LED, but it's really strong. Even after big frontal impacts and 1 bulb which broke and bent, all work even after approximately 8 packs (including the twisted ^^).

In any case, your assembly would interest me well Nitro_Hawk! Do you think you can send me a plan (for worthless) by pm please?
If you need information about the differences XXL/B-XXL, don't hesitate.

And sorry for my bad English...

I have to do another set for a friend this weekend so I'll take photos and post the whole process with instructions. It's not complicated but can be somewhat time consuming if you are not into this kind of stuff.

Those hobbyking lights seem strong in the videos!

Cool, thanks!

Yes, these lights clear strong, but they don't give out heat. Thus, for the moment I didn't too much worry, they are directly connected to the receiver. I hope this one risk nothing, at the beginning I hesitated, then finally...

Later, to avoid discharging the 4S, I shall connect them has a battery made by 4 or 5 AA Eneloop.

Quick zoom on my B-XXL (I tried in fact to make a photo... ).

For information, while I think of it :

I had to verify for the pinion gear, it's really a 15T on the B-XXL.
Moreover the ESC is also a little different from that picture, because "it's" in carbon.
These photos come probably from a proto...

Hey, got you the pictures of the led assemblies.

To prevent LEDs burning out it is recommended to solder a resistor, in my case I used 280ohm resistors. Cut the + pin of the led short, soldered the resistor and used heat shrink to keep things tidy and prevent any short circuits.

Here is a picture of a LED with the resistor in place and heat shrinked. Besides it, how I arranged all the pins inside the pod: All the + pins join up at the middle, - pins go around joining each other, the negative from the center LED is routed through a gap between plastic. Each pod has 7 LEDS connected in parallel.



Cut the joined + pins shorter, welded the cable. Welded the - pins together with the negative cable. It is very important to keep things compact because of the lack of space inside the pods.



After doing this it's just a matter of routing the cables through the slots at the back of the pods and re assembling them.

I used 3.2v leds so hooking both pods up in parallel to the receiver would burn them out instantly since it provides little more than 6v. To overcome this you just have to wire the pods in series.
Positive wire of pod A goes to + on the 3rd channel of the RX.
Negative wire of pod A goes to Positive wire of pod B.
Negative wire of pod B goes to - on the RX.

Then assemble them as you want, here is an example on my XXL

Nice, thanks for the pictures Nitro_hawk!! They're more beautiful than HK mines, but they not so much light.
But it's normal, on the HK there is 12 LED by headlight!

Bare in mind those are regular LEDs, there are high intensity ones you can use.

I've seen those videos before, that was the first I saw of the XXL ve on track and made me change my nitro to the brushless one.

Love the track layout with the different surfaces. Wish we had more tracks like that one here.

Besides being a sand rail, I tend to think of mine as an oversize 1/10th mid motor 2wd buggy that can survive the jumps of the 1/8th off road tracks. Love it's dual purpose and it hasn't let me down on either front.

Anyone found a solution for the diff problems?

I had this issue 3 times already (bought mine in August). The pins start to wear down the plastic on the diff cup, then go off alignment. This upsets the clearance between the internal gears, which gets too tight and ends up breaking the gears or binding the planetary gears against the cup locking everything inside.

This is premature wear due to poor design and choice of materials, the diff is clearly too small and weak for the power and weight of the application. Truggys split the loads between 2 similarly sized diffs via a center one, this uses only one to handle everything, not to mention the extra weight and size of a 1/7th scale.

So if you have a sun or planetary gear go wrong check the cup, it's very likely that you'll need to change it or you'll blow up the new gears in no time.

I just fabricated a locked one to avoid further issues while using it hard.

I don't have this car, but I'm interested in getting one maybe, if I could fit in a big motor. I read the stock motor is some non-standard 44x70mm and was wondering if I could fit in a 56x82mm or a 1717 (50x85mm) motor. Anyone happen to have tried?

Anyway, I had these Losi 8ight diff cup measurements taken for someone recently, and wondered whether those would fit. I only had the standard Losi 8ight diff cup out, but given it is a direct swap with the Heavy Duty ones, measurements should be the same.

The Heavy Duty ones (http://www.amain.com/Losi-Heavy-Duty...al-Case/p22791) have these metal inserts so the spider gear pins don't dig into the plastic cup under heavy loads. I use them in my slightly overpowered 8ight-T: http://www.rc-monster.com/forum/showthread.php?t=32131, and they work well. All measurements below are in mm.













Maybe you can use those.

I have to do a tear down on mine for this weekend, I'll measure the engine mount and clearances for you.

I haven't tried messing around with the Motor/ESC yet. But so far 4s with a 15t pinion does the job, 6s would be too fast, 5s might be the sweet spot. Being 2wd traction is the limiting factor 90% of the time, only 2 wheels do the braking too so that's another problem.

Thanks for the idea on the diff, I'll measure mine, if that one doesn't fit I guess i could machine some pin bushings to get around the problem!
