I saw one, i was going to get one until i decided to get a new monster truck. I was watching and tsalking to a pro that wass sponsored by a different company for engines, but he was running a diablo instead, and said that he can usually get a 10-12 minute run time with a stock 75cc tank(craziness), it had the highest top speed at the 05 nitro challenge(34mph), and it started easy. I watched, and he did everyjump on the track we were at, and there were jumps my dads revo wasn't even able to do. This motor looked truly awsome. IO would say get it, i will definately be getting one as soon as i get back into the 1/10 scene. Go Diablo!!!!
