Hiya,

The 600's are easier to fly... no question.. They are better designed machines too just a little bit pitchy at medium slow forward speed (this is a trait of trexes though). My 450 isnt too bad considering its really a dememted bumblebee in disguise , it runs 2500+ RPM at the head (its a 4 cell setup). I Im running 30% expo on it though lol. If you want to tame yours down a bit, try weights on the flybar. That clams them down a bit, that + expo. The other thing that might help is winding up the headspeed a bit... You'll need to find the sweetspot though because too high and they turn into hornets and too low and they become very "fidgety".

Hope this helps... Azzy
