New Twin Hammers Owner - Question about noise

Newbie here. I bought 3 RC's and received them all last week. A Traxxas Slash 2wd Courtney Force, Vaterra Twin Hammers V2 RTR, and an Axial SCX10 Deadbolt.

Running the three RCs together, the SCX10 is practically a stealth-mode rig. You can barely hear the motor/esc/drivetrain. The Slash is pretty close, just slightly louder. In comparison, the Twin Hammers sounds like a bag of angry bees swarming a lawnmower.

From all the videos I've seen, it seems the TH's ESC always makes that annoying whining sound. But I never really paid any attention to the sound the gears make until hearing just how quiet the other two cars are.

Is this normal for the TH gears to be that loud? I took the motor/transmission out last night and popped the case open and couldn't see any signs of damage. Upon closing the case, I noticed it was even louder than before (very rattly sounding). Slightly loosening the screws eliminated the rattling.

Oh yeah, there was no grease inside the transmission. Is this normal?

VTH transmissions are said to be noisy. Mine, like yours, sounds very angry compared to my wraith and scx10

Re: New Twin Hammers Owner - Question about noise

If your a hammer is a RTR chances are there is no lube in it. They say you do not need it. :lmao:
Twin hammer trans is louder as well, more gears more noise.

So should I open it back up and put some grease in there? If so, any suggestions on what grease to use? I do have some white lithium grease on-hand.

I would use the stickiest stuff you can find, I use molybdenum with Amsol because I have it and it is quite sticky. Anything would be better than how much they come with, in my experience.

As you've found, tighten the tranny case screws snug, but not too tight. Lube the gears with something good and sticky, Lucas Red and Tacky grease is nice. "thumbsup"

The RTRs benefit from a bit more grease than they seem to come with ime. "thumbsup"

Re: New Twin Hammers Owner - Question about noise

I don't want to send the thread on a tangent but just on the issue of noise, has anyone compared the steel gear noise with plastic? Is one quieter than the other or about the same?
