well i have a blackjack 26 and i cooked 2 hydra 120s one running a feiago 9xl on 4s8k and another running a medusa 80mm 2200 on 4s8400. i just stepped up to a hydra hv 180 and it is a great controller. and now ill be about to throw it in my shockwave 36 on 8s. i was really hoping to get a 1500kv medusa for that project but as i was about to order they folded. so now the savings begins for a 1527
