IDK what kind of kit you have but below is a cutaway pic of a traxxas Rustler/Slash/Stampede 2WD transmission and most 2WD transmissions are pretty similar to this. The largest gear at the top is yopur input shaft which holds your spur gear and slipper clutch on the outside. The smallest gear in...
Yes, I use it in quite a few of my bashers. I even use it in the transmission case of my 100+MPH Rustler.
I would not use white lithium grease, I've read its bad for plastic.
When you say increased traction are you talking about limiting wheel spin? You would do that with the slipper clutch. If...
You can gear it however you want to, the important thing is not to overheat the motor and burn it up. I dont like to see my motors going above about 170-175F
You can also try and find a 32P or Mod1 spur that will work too and then you'll have more options for pinions. Like Fog said too if your just looking for more speed try a higher KV motor. What motor are you running now cuz 45T pinion and 81T spur is already a really short 1.8:1 gear ratio. What...
