For me, Robinson Racing seems to be the quietest and most precise pinion. It is MUCH quieter than my Tekno pinions. I haven't purchased a Novak pinion in a while, but have read good comments about them all the time.

for the servo, I got one of the Protek 170S servos as well. Works very well.

for the pinions, I have been using Novak pinions in my SCT410 and EB48 and have been working well and are very quiet. Started with a Tekno pinion in my ET48 but have a Novak pinion installed now. It is slightly noisier than the other two cars, but I think that is because the spur is rubbing on the center diff top plate. Nothing too serious though.

Tekno has these listed as the newest diff shims for the ET48 TKR5145B if anyone is still having problems with them.

I just got some in stock now, and their great. They solve the problem! I use them in my own stuff. Where the old ones would wear.

I've heard several people say that the Novak pinioned are the quietest.
That said, I've also made my Teknos quieter than most with the Tekno pinions simply by running the gear mesh mo tight. Due to the great tolerances and balance, I've been able to go tighter mesh (less chatter) with no binding than I can on several of my 2wd 10th scale vehicles. That in both an eb48 be sct410, though the same should apply here.

Give it a shot, make it as tight as you can without having a spot in the rotation with no play/chatter at all.

Thanks to all for the pinion advice. I have played around with the play between my pinion and spur and I did notice it was a little quieter with a closer fit.

I actually forgot about the spur being right up against the plastic plate over the center diff. I bet that's part of what I hear sometimes when hitting the throttle up the face of a jump or other situations where I'm probably getting some chassis flex.

radiopost signature series at 7.4 for me. works great on all my teknos

I pulled a Castle 1717 1650kv from a traxxas XO-1. Can I use this combo with 6s lipos on my ET48? What pinion do you guys recommend

The truck is really limited on ESC and motor space, I think its about 125mm of space for both combined. The 1717 motor is 85mm long so that would leave about 40mm of space for a 6s capable ESC. I don't think there are any that small. There's not much room with a Tekin truggy motor which is nearly 10mm shorter than the 1717.

Edit: Possibly an RX8 could fit with the 1717 motor depending on exact measurements

My oponion is that Tekno pinions the best. Good hard steel, easy to read tooth count while still installed, large setscrew.

I got a issue, maybe ya'll can help. I have the traction drive installed. It works amazingly. Just that it get hot, and It should as it allow the clutch to slip. My issue is the set screw keeps coming lose. I've tried several different spring tensions and that doesn't effect it any. I've also tried different lock-tight. I understand that heating up lock-tight will break it down and actually causing it to lube the screw. Is there a high temp lock-tight? What can I do to keep this from coming loose and backing down the shaft? I thought about drilling a hole in the shaft and using one of those set screw/pin. But I scared that will weaken the shaft.

It's as simple as Dremel'ing a little scuff on the shaft. Then get a new set screw and thread lock and tighten it down good (with a good hex tip). Shouldn't move after that.

SO, I am absolutely loving this truggy! I ran into an issue with the switch though yesterday while burning some laps... My truck just stopped at one point and I couldn't for the life of me figure out why!

After I got home and started taking things apart little by little I noticed that a rock got lodged down by my ESC and the drive-shaft. When I pulled it out I noticed that it also was rubbing on the wire to my switch and that was where my problem was.

Is it going to be an issue that I cut the wires for the switch, twisted them together and taped them to the side of my ESC? Now to turn it off or on I just plug it in or unplug the battery. I don't think there should be any problems?

Good question for the vendor of the electronics you're using, not really Tekno. That being said, I don't do it as I have never had issues since I just a dab of CA glue to attach the switch to the ESC, but it's a pretty common practice to cut the switch and connect the two wires.

to make more room, lay ESC on its side that might help with your fitting space
