That's a good point you have there about the prop breaking... I dunno why I never thought of that before =P

Truglodite or something like that has done that before, dunno if it was a 9T though.

Oh yeah, and BTW half the guys in here fly Pro's or so far upgraded CP's that they are basically Pro's anyway. The Pro forum doesn't see much action, but we all have alot of fun in here.

Dunno if you have looked at it, but the dual tail is also a reasonable option =)

Oh, and trimming your rotor, you will run more volts through the motor, but probably not more amps. You'll just need to turn up the mixer like you already said. It should give you better spool up time though because the prop is smaller, I dunno how that would change the authority of the tail (less more or the same)
