Absolutely!  Probably the motor won't comfortably pull 12 degrees of pitch

but I bet it'll come close.  I'm running around 11 degrees on my HDX450 
which is essentially a T-Rex clone  You'll have to experiment around to 
figure that out.  All you wind up doing is running 90% (or whatever) on
the 
pitch curves to tone it down a bit but it's nice to have the mechanical 12

degree for autorotation time.

With a mirrored collective (-9.5 / 0 / +9.5) you're hovering around the
3/4 
stick point.  That means the collective curve is a bit compressed relative

to what it would be if  you were flying the old standard (-4 / +4-5 / +10)

curve and hovering at half stick.  I know some pilots that fly the
mirrored 
program all the time but I'm of the old school (pre-computer radio days)
and 
prefer hovering at half stick.  Probably, you'll like the collective feel 
better when you finalize your collective setup.

Considering that you're not pu****ng the collective range limits, it's
likely 
that you're pretty soft on the cyclic throws too.  I've run the swash
mixing 
as high as 65% for all functions without issues.  You just need to make
sure 
you're not binding servos and/or swashplate controls in the process. 
Also, 
I think the standard flybar paddles on T-Rex's are relatively
conservative. 
There are lighter versions out there that will speed  up your cyclic 
responses when you think you're ready for that.  :-)

Been there, done that, got the t-****rt!  :-D
