Major Features Compared to V1.1:

1. Balance Multiple engines and multiple sensors (now up to 2 x 2). User can select 1 or 2 engines, and 1 or 2 sensors per engine. This can be easily modified to n x m (engines x sensors).
2. Added "Demo Mode".
3. Improved review and printing formats.
4. Added "Retake Data" option.
5. Added "Re-Split Weights" option even for up to 3 weight locations.
6. Added a "Picture" to show weight locations and propeller rotation direction.
7. Added "Re-Enter Weight" option.
8. Added "Convert Test Weight" to "Permanent Weight" option based on the installed radii.
9. Added "Change Global Settings" menu, which now just includes the propeller rotation direction (CCW or CW).

VERSION 2.01 Oct 17, 1996

1. Support Two Sensors at different angle positions.
2. Added Influence Coef. entry option for different sensors.
3. Able to view and print out Influence Coef. for different sensors.

VERSION 2.02 Dec 03, 1996

1. Use a new method (Least Square) to optimize the solution for 2 sensors (if one sensor is used, the solution will be the same as before).

2. If the influences of both sensors are known in the initial run, you could do just one-shot balance.

VERSION 3.00 March 15, 1998

1. Support 1725/1730. But if used on 1700/1720, only single-engine balance is allowed. For 1700/1720, should use v2.02.
2. 100% N1 and RPM direction can be entered in "Global Settings".

VERSION 3.20 July 18, 1999

1. Add 1720 twin engine balance capability.
2. Different Engine may be entered different balance RPMs.
3. Use new ICFs computation method as for TFE731.
4. Support Year 2K.
