Castle has a new ESC/motor combo that looks really interesting: MMX8s with the 1520-1650KV sensored motor. At first brush, this looked good because I saw that their cryo-drive technology keeps temps down which is something I'm interested as I live in an area that gets really hot in the summer. But I read that the MMX8s was having fan issues. Not sure the percentage but some folks are having some issues. Then I was curious about how much this changed top speed... it was really a small amount. I'm not going for a 150mph speed run, just using that as a benchmark as to what would change. With the added weight, seemed that it would accelerate slower. I don't know exactly how much extra weight as there is no weight for the 1520-1650Kv motor but the ESC and batteries would be about 4.5 oz heavier on the 8s setup. It almost seems like it would be a minor change.
So it made me question why Castle would recommend this for the Felony. Don't get me wrong, this isn't a poke at Castle at all, quite the opposite really. I am probably missing something which makes this a good upgrade but I'm not seeing it. Spektrum Firma 150A 6s with 2050Kv vs MMX8s 8s with 1520-1650Kv... what is the big difference? Please educate me.
