I Rossan ,
please do not get person ,
but my name is Nico and not Nick or Nic :-)

About the PREDATOR delivered hardware , is good .
In the box you can find CNC cutter fiber bell crank .
And the elevator system is based on a carbon push road .
About the last , consider that the best is sure a KATO ball bearing
system ...... but the delivered one make the job!
The only problem is that you have to lose few minutes to setting the
exact excursion on the two elevator surfaces .
cheers
Nico
