axial yeti kit
 

Hi, i am going to by the yeti kit and am looking for input on what esc/motor to use. I will be running it in open areas ,jumps mud and very little crawling. Would like waterproof and ability to run on 4s. Any assistance would be appreciated.

A brushless system intended for short course trucks is the perfect size. The only systems I know of that is 4s capable is the Castle Creations Mamba Max Pro SCT with the 1415 2400kv motor and the Hobbywing Xerun SCT Pro 1/8 system. There are other 1/10 SCT esc's that are 4s capable but they don't come in a combo with an appropriate motor. Just make sure there's enough room in the chassis for the motor as 4s capable motors are typically longer, in the 65-74mm long range.

4S LiPo in a Yeti? I don't know what the battery compartment dimensions are...yet. I would like to think that a 3S pack will be plenty enough "juice" to propel that monster buggy/rock racer. I would do a www search, until somebody chimes in here who owns a Yeti and can give some insight, and see if you get any videos showing a 4S being put into that Axial.

Just by reading the specs from Axial : The battery tray is fully height adjustable with four button head screws, making room for most standard sized 2S and 3S LiPo battery packs.
