BOZ I'm surprised you struggled with space for the electronics, with my motor in the rear position i had more space than my 15.

It's probable more the esc side. It hard to layout neatly when the capacitor doesn't stretch to far.

You raise a pretty good point Looking at Bozs picture it looks pretty tight and I assume that's in the front position

Be interested to hear other people's experience.

When running the motor in the rear position the nut will interfere with the motor.

As the rearward position is meant for really loose low grip conditions you can run it without the screw/nut without issues

Time to hit the track. I'm excited.
It would help greatly if you rotate the ESC 90* to the right, run smaller wires and run them through the lower front brace for the battery and esc.

We're running full size servo, 2 x capacitor banks and extra fan for the 4.5T motor with space to spare. The '15 and '16 have a lot more space for electronics than the '13 and '14 had

Yeah, I noticed it too.

Why put 2 holes in for the battery position and not motor position. ops.

I hope they do a rolling update on the chassis one day. I think we can manage to drill a 3mm hole in the side guard.

Anyone?

As likea45 says the steel gears are louder than the composite gears that were standard in the '13 and '14.

The '16 should however be comparable to the '15 in terms of how it sounds.
Just remember to grease the gears and make sure gear mesh is okay for the pinion/spur.

I've also witnessed some managing to not have the bearings for the spur entirely seated causing the spur to not track straight

As mentioned the rear motor position is only used for really loose and blown out tracks and then you run it without the 4th screw (front, ESC tray and back).so not really an issue.

If you really want to run that last screw either drill a new 3mm hole (takes 30 seconds including countersinking it) or use a low profile nut instead of the standard one (or just Dremel it down).

Cheers.

I finally found the pictures of Bruno's car (body off) again. Turning around the ESC by 90* didn't work for me last night as one of motor wires were hitting the motor mount. I did notice that Bruno positions his ESC towards the outer of the chassis where I had mine closer to the centre line of the chassis. I think when I tried it, the steering bellcrank was hitting the wires coming out of the ESC and that's why I didn't like it facing that way.


I'll has look at it again.


I have never been a fan of running the battery wires via the brace. Having to unsoldering a brand new ESC just sounds like a silly thing to do. I'm always worried about blowing it up before I use it.

As you can see in my photo I'm running my wires under the front brace but with the motor in rear position it comes up 5mm short so the wires keep piping out, i was wondering if you (bentka) could give me a suggestion what to do cause at the moment if they pop out they will go straight into my spur gear which will eventually lead to a DNF or even worse a short circuit. Thanks in advance.

The part # for the medium side pods (XRA361265) was readily available. Does anyone have the part # for the medium chassis brace/s?

For those that are running 13.5 class with your XB4, what are you running for gearing? I've searched, and seen most are dropping their spur gears down a few teeth. Is this 100% necessary? Can you reach good gearing & speed with the stock spur? If it matters, I have a 2014 xb4. And have a speed passion 13.5 motor I'm throwing in to try the class out.

I don't run 13.5 in wheeler but I run 17.5 in 2wd buggy and usually you can get the same or nearly the same gear ratios with the larger spur, but going to the smaller one will change motor position. so you could get the motor a little closer to the center of the chassis with the smaller spur, since balance and weight is more critical with 17.5 & 13.5 classes.

Composite chassis brace Front - Medium #361294
Composite chassis brace Rear - Medium #361295

Should be in stock with distributors/dealers that ordered when they first became available

You don't want to swap out for thinner and more flexible wires ?

We use thinner and more flexible 13ga ORCA wire (TQ Racing also have this) and direct the wires straight out from the esc instead of straight up.

The thinner and more flexible wire also don't have any pull to them so they stay in place.
