Good valueReview by Bill
Ran this in a 2wd monster slash and now it's in a 4x4 stampede. Great motor with good power. Has been through quite a bit of mud and water and still going strong. (Posted on 1/5/2018)
great motorReview by Bill
I bought the 3500KV. This is the first 4-pole motor I have owned and is the first motor I have owned with this high KV, so I can't say I am basing my review on comparison to similar motors. However, compared to the motor I was using before, an EcoPower Sling Shot 17.5T 2200KV, this motor is way more powerful and faster. It has exceeded my expectations, and the price $29.99 seems like a steal. (Posted on 5/2/2017)

What esc is recommended for the 5200kv motor thanks

The link above is a good pairing for this motor. It's waterproof as well and suited for 2wd 1/10.

Not recommended for 4wd

will it plug rite in to my traxxas velineum system
Not sure if the Velineon ESC's have 3.5mm or 4mm bullets, but I believe they are 4mm. These motors have 4mm plugs on them.
