For an LST2 system, you'd be better off with a Castle Monster or a Tekin RX8, so you can run either 4s or 6s. I have run the Hobbywing 150A on 6s in a truggy till they wouldn't allow it at the track anymore. It was so fast you were off track all the time, but man was it fun. I run the 2000kv Tekin truggy motor now on 4s, the pack doesn't last as long but it flys. Novak ran his system on 5s for a demo, but I don't feel it will take it long. It's great for 4s and sensored is the only way for racing( CONTROL) being the name of the game
