Hey guys,

I've been doing some reading on the site and find that most people here high higher-KV motors in their Yeti's. My yeti is primarily a basher / trail rig. Here is my current gear setup:

• Stock 3150KV motor
• AXI30402 Underdrive Gear Set in both the front and rear differentials
• SSD Cenetered Rear Axle
• Stock Spur Gear
• Can't recall what pinion gear I have installed
• Hot Racing 2 Speed Gear Set
  • By the way, this gear set is awesome! The shifter sucks ass though. Highly recomend using Axial's shift lever instead AX31183
    
  • It is much more consistent, and provides a better linear travel during the shift. Much smoother. Downside is that its not a direct fit due to different thread sizes. Some minor trimming on the plastic shifter fork allowed it to fit into the HR gear no problem though.

Lately I'm really enjoying going somewhat slow and climbing over obstacles in low gear with this vehicle, so I was thinking that since I already have the Castle Mamba Monster X ESC, I'd pair it with a Castle 1406 2850kv motor


If I want the extra speed, I can always combine two 2S batteries or purchase a 4s battery, but I think for the most part I will be running it as 2S or 3S.

Would this motor be a good fit for my use case?

As far as the Diff Oil question goes: Currently I have a locked rear diff and 1M CST diff oil in the front. This has served me pretty well, and I'm enjoying what the 1M oil does but was curious if anyone ran with higher weight oils in the front / unlocked diffs with a high weight in the rear.


Specifically, I was interested in either the 2.5M / 20M oil by GravityRC. I feel like the 20M oil would be a bit too heavy, but I could dilute it with a lower weight oil if needed. Anyone have experience running heavy oils like that? I'm likely going to purchase the spider gears to swap over to an unlocked rear diff, hence the question.


Finally, I have these shocks on my somewhat heavy rig, and was wondering if anyone new of stiffer springs for them:

I already purchased their Spring Assortment, but was looking for something slightly stiffer to keep the front shocks extended further. I haven't had any complaints about the rear shocks , as they keep the rear about where I want it.
