The reason for the issues......as in it's almost always an user error.

She got taken out by other drivers......which is usually what they end up doing when they can't outrun her.
Nothing new to us but getting a bit old now......

Hmm if they go after the car intentionally they should be disqualified ASAP!

it's not the way to drive and ppl have to remember that a lots of other new newcomers/drivers maybe are looking and learn that this behavior is "okay" its a sad way if the sport go in that direction but i guss it's hard to get beat by a little girl.

we were running 78/28 if I remember right, with Certified 1s Trinity. plus a heatsink and fan.

In 98 out of the 100 times I help people at the track with stripped gears one of these things are the culprit.

Sometimes I wish everyone should have been forced to own a late 80's or early 90's race car running brushed motors and Nimh batteries before owning any R/C car at all so you would actually know the real struggle of keeping a car race ready

YES, we have it so good now. I love that I ran a motor for 3 seasons an never had to do anything to it.

As far as over tightening, what torque value should the screws have, after threads have been chased in the bulkhead and diff? I have a really nice torque wrench that I can use to set, then find out where on my electric driver the clutch will stop driving them at about the correct torque.

I'd like to see and answer to this. How do we determine if we are over-tightening the screws?

In 98 out of the 100 times I help people at the track with stripped gears one of these things are the culprit.

For the remaining 2 out of 100 we change parts, problem goes away and we never actually pin pointed the exact issue.

What I'm trying to say is……..I'm always told by the owner that everything's perfect and every part has been inspected before I start disassembling…….but almost every single time I find one of the top 4 things on the list to be the culprit……why is that

Race kits with todays high powered motors (we run a boosted 4.5T) DO demand some actual maintenance from the owner to be able to withstand the abuse we throw at them.

Sometimes I wish everyone should have been forced to own a late 80's or early 90's race car running brushed motors and Nimh batteries before owning any R/C car at all so you would actually know the real struggle of keeping a car race ready

Here's Malin running at the worlds with her XB4 '16 with boosted 4.5T and slipper set to absolute minimum = 0mm gap.

So I can't for the life of me understand why people at the track need to run their slippers cranked down……..and then proceed to cry about why their gears wear out

The answer I usually get is; "I'm having problems clearing that jump……"

What a load off rubbish the typical crap we have come to expect from team drivers denying there is a problem and trying to make out that us the consumer are the problem, let me tell you something bentka i have been in rc since the 80s and no exactly what it takes to look after a race car, at the end off every race day i pull my xb4 down rebuild shocks, diffs, oil bearings and change any worn out or damaged parts yet i still keep having rear gear failure. If the gear is failing due to the handful of reasons you mentioned above then why is it only happening in the rear off the car and not the front i build my front and rear bulkheads are built exactly the same and why does X-ray not mention any of these building tips in there instructions, and before you say it i run my slipper with zero gap, so before you come on hear and fill our heads with rubbish and try and make out the gear failure is our problem think again, its time X-ray stopped denying the problem and just fixed it, don't forget we have seen this kinda of rubbish done before like when they tried to make out there was no problem with the rear suspension holder. I understand your need to defend X-ray as you are part off the factory team but please don't insult my intelligence and tell me the gear failure is my fault and also why does the problem only occur in my modified xb4 and not my stock one. And so you no i love X-ray and also hate when people rubbish XRAY, in my opinion it is the best kit on the market thats why i own 4 of them. FIX THE PROBLEM AND DONT TALK CRAP

Then why can I race all year round and not destroy any? I'm still using the composite gear too!!! Our track had sugared surface, It was only changed 9months ago to a more natural dirt. The last time I striped any gear (satellite ones) was at the Mildura Nats on sugared track, about +2 years ago.

Thanks Bentka for the list of things to look for. We have a driver at my track striping gears, but he is running my first XB4. It's old and well used by now.

Yeah, that was a bit of a balls up. Personally, I didn't notice any difference after screwing the updated hanger on! I think Xray looked at it from there POV which they believed was correct, only when it was pointed out by a few onwers, some was done and they made the changes. Hey, not one of us complained about it in the first two editions of the car.

I'm sorry you have these issues with your XB4.

What I'm trying to do is to share my personal experience with helping tons of Xray drivers firsthand on the track throughout Europe and from all over the world over the internet through forums and social media.

We get anything from 20 to 50 drivers approaching us every week for support, setup tips and mechanical advice.

I always try to do my very best at the track to help everyone to the best of my knowledge no matter if you're a first time driver or an experienced racer.

My personal experiences from doing so is also what I relay back to Xray.

This is not a pissing contest by any means.
I've done this since I first started racing R/C cars in -79 and I will continue to do so no matter which brand we represent.

Wether you want to listen to or follow my advices is entirely up to you though.

If not then feel free to just ignore my posts or even put me on your ignore list

Pls don't get me wrong i really appreciate the input you have on this forum but i didn't like your last post which blames the owner and not the car, especially when i have tried every thing you mentioned to no avail, the funny thing is the stripping of the gears does not bother me in the slightest I'm happy to replace a $10 gear every now and then because its the only thing that ever fails on my XRAY, and i would rather have a buggy that i only have to spend a couple off dollars on every now and then, the way i look at it is there are cars out there which break every time you take them out and cost an absolute fortune to maintain, for me a stripped gear is a small price to pay to have the best most durable kit on the market.

Again another sponsored driver is trying to tell me its my fault the gear strips, for every one person that doesn't have the gear failure theres 100 that do, the problem is so bad X-ray can't even keep up with the demand, gears and front drive shafts seem to be out of stock all around the world all of the time and your trying to tell me theres no problem and that me and the other hundreds of X-ray owners are wrong and your right. STOP DREAMING of course you can't admit theres a problem cause if you do there goes your sponsor ship.

I ran dingo desc410 gears for 3 years before they wore out. I got 6 months with my metal gears with xb4. Propperly shimmed and never over tightened the bulkheads . Slipper set properly after burning through composite gears...
Still my fav car to run though.

My 15 XB4 had no issues with any of the gears. I ran her with the slipper and also with the center gear diff up to 500k. I was running graphite gears all around with aluminum diff pins as well as the comp/graphite crown gear and drive.
Lightly greased with Eureka Pro Lube buttery smooth.

If I buy a 16 I will run the graphite gears all around as well as aluminum diff pins. Silky smooth, ninja silent and really reliable.

2 1/2 indoor seasons on my XB4 '14 no stripped gears and only ever broke 1 part. Rear A-arm broke at the shock mount because I tried to put the screw from the front in there. I have a spare set of composite gears that will be going in the '16 when I get it.

Always have ran black grease on mine. My buddy that I race with has had 2 sets of gears strip out on used cars that he bought and in both cases the gears and case were bone dry. Not sure if that contributed to them stripping or what but I found it very odd.
