Hey Tommy R, I bought these sound units before and they look the same but a bit cheaper if you are interested.http://www.rcbrmin.com/index.php?mai...roducts_id=786

Thank you for that! I see it says not to use a LiPo, though. What kind of battery do you run?

So whichever transfer case I end up with, I'm pretty sure I'm going to need a gear reduction. Using an Axial trans/t-case and a 2:1 gear reduction unit (GRU) would get me to 5.2:1 reduction over a stock setup. That's pretty darn low, but not sure if it'd be TOO low. However, I can't locate any 2:1 GRUs. Closest I can find is a 3:1 unit. It's cheap so I went ahead and ordered it.


Doesn't look to add much length to the motor.


Now I'm thinking the Axial t-case may be too low so I may consider a unit with a little taller ratio like 2:1. I have several options. I'm open to suggestions from those of you who've geared down your trucks. Knowing I plan to take this thing offroad and pull reasonably heavy loads with it, what kind of overall gear reduction should I look for? 3:1? 5:1? 7:1?
