Phillip, gather your gears and send them into AE. You and the guys who experienced this represent what they would likely consider an extraordinary failure rate. I bet they'll want to check those parts out.

Maybe the gear cases are a factor. I noticed I had to loosen and tighten it a couple times to get everything to line up before I put it in the car. It's only molded plastic. A friend of mine put an aftermarket laydown in his kyosho a couple of years ago and he kept blowing idler gears because the case was a little off.

What’s this car coming it at for weight in box stock 17.5 form? (Light motor, stock esc etc).

You ran direct drive in a very high bite situation with a 13.5 and more than one of you all had the same result....... Don't get mad because I'm right.

I don't believe you're right. He and his buddies wasted almost as many idler gears in a race day as I've seen go in 30 years of racing (we didn't always have slipper clutches, either), running in rather unremarkable circumstances. A 13.5 just doesn't make gear shredding torque.
Phillip, also check the machining of the lay shaft gear, check for sharp edges on the tooth profile?

I used a fan mount from rc speed secrets. I drilled the hole out for the rear side guard and installed a longer screw. Then secured it with a nylock nut. No body clearance issues. Obviously this only works the the Associated lockout installed. I don't know if you could move it around to work with a slipper, but I wanted to share this with others trying to mount a fan.
I'll post some pics when I get a chance.

But they do. I shredded plastic diff gears in a b64 on astro paired with a 13.5. But on dirt they are fine. The ultra high bite surfaces we are running today are a lot different than anything in the past. Were the gears I was using defective...no. Was I using them in a situation that I shouldn’t have, yes. My bet is the direct drive in that situation...especially since it repeated itself multiple times. There is zero benefit to using a direct drive in that situation.

The power of the motor is not what is causing the problem. If you are running pin tires on carpet (basically 0 slip), something has to give. Even with a 17.5, when the throttle is applied in the air and the car lands, the rotation momentum of the drive train must be absorbed. Without a slipper or tires/racing surface that gives during landing, the next weakest link will fail and in this case, that appears to be the idler gear.

4 different guys in one day? Just seems like too many to me.
I agree about the slipper. I run one in all situations.

While it may have been ok (doubt it) in 17.5 it definitely wasn't in 13.5.

Still not buying it...

what is there to buy?! You agreed about the slipper. You said you’d always run one. The issue here is a direct drive coupled with pin tires on high grip carpet. Something has to give. I give up.
Run whatever you want but don’t complain when you ruin stuff and blame the manufacturer. It’s definitely no your fault....
