Visual Blade Tracker “Strobex 135M-12” P/N 8620
This Blade Tracker is used with V2K(+), Carry-On VXP and 8500C(+) to observe the Track & Lead/Lag of main rotors and also tail rotors of helicopters.
It requires “Tip Targets” on the blade tip which are usually part of the Application Kit for V2K(+), Carry-On VXP and 8500C(+).
Observed Track & Lead/Lag data are either recorded on a tracking record sheet or entered in the 8500C(+) “Smart Chart” to be respected in the calculated Track & Balance adjustments.
Optical Blade Tracker “FasTrak” P/N 11800-3
This Day/Night Blade Tracker is used with the 8500C(+), Carry-On VXP, On-Board VXP and VMS II for fast Track & Lead/Lag measurement of main rotors of helicopters within +/- 1 mm accuracy.
When used with Carry-On VXP the Track & Lead/Lag data are collected simultaneously while measuring the dynamic balance.
For use at night, a Retro Reflective self-adhesive tape is used at the trailing edge of the rotor blades to reflect the emitted IR light of the IR LCD ring below the cover glass.
Portable Printer “DPU-414-M”
This portable printer is used for V2K(+), Carry-On VXP VMS II and On-Board VXP to make printouts of rotor settings, measured data and rotor adjustments as well as predictions for the calculated adjustments.
This line printer makes it comfortable for the user, to get printouts at the aircraft, without the need of a PC Printer in an office.
Its rechargeable battery allows printing even without supply power from the aircraft. The rechargeable battery is charged via the Acquisition Unit of the Carry-On VXP.

For Carry-On VXP “Advanced Smart Charts” are provided on a Compact Flash, available for many helicopter and turboprop aircraft types as well as for some turbofan engines.
The “Advanced Smart Charts” of the Carry-On VXP allow simple/quick data collection of Track & Balance of one or multiple regimes and calculate rotor adjustments for Track and/or Balance respecting current settings and rotor limits.
For 8500C(+) Chart Sets are provided in form of a 3.5” Floppy Disk, containing “Smart Charts” available for almost any helicopter and turboprop aircraft type as well as for some turbofan engines.
Precision Tab Tools (optional)
The fine trim tab adjustments calculated by the 8500C(+) or Carry-On VXP require accurate measurement and adjustments of Trim Tabs.
Precision Tab Tools are available for many different helicopter types from Honeywell, supplied with calibration plates and instructions and partly with a specific carrying case.
