The ACIS SIX is our new affordable non-sensored brushless motor. The design has most all the features of our KRATOS SIX minus the sensors and timing. This non-sensored version is very durable and completely element proof. Beat it, bash it, under water/mud -- it doesn't care. Unbelievable battery efficiency will keep you on the trail longer. All wiring included this guy is ready to bolt in!


1200kv version is for the more serious crawler who is not worried about wheel speed. With its ability to run a 6s lipo, it will still get up and go if needed. Recomended pinion 12t or under.


2100kv version is for serious crawling yet just enough wheelspeed to keep you happy. 4s capabilities will keep even the speed freaks happy. Recomended pinion 12t or under.


3000kv version is for someone who wants to crawl but still have some room for speed. Also capable of using a 4s lipo for the insanity! Recomended pinion 11t or under for optimum crawling.


4600kv version is for the insane. 3s capable this guy packs a punch. Great for mega trucks and faster applications. However, a little secret is throw an 8t pinion on it and you will be surprised at how well it crawls. This is what I will be running
