I now have my Blade-400 turned up to 2500, 2800 and 3100 rpm with no normal mode, just 3 idle ups. I have been getting used to flying at the higher head speeds. I am doing tic-tocs keeping the tail stationary and some really tight funnels and inverted fig. eights. I really love that little heli, it is SO fast!!, it makes my big Raptors look like slugs! I have six Kong Power batteries now so I am good to go. I also bought the Triton2 Equonox charger and I just love that thing. I am getting a Trex-250 because I just think it's the cutest little heli out there.
