I used the same drive unit, gyro, rudder
refernce, etc to just make the wiring
The X10 was a cleaner install than the 100 for me becuse I had an add on gyro unit.
Really the only tricky thing was making sure the control head worked with the Seatalk
(there isa work
around for using the old Seatalk with newer Seatalk NG).
I find that the X10 works quicker than my old type 100 and I normally use it at a response level of 2.
