4-29 – Propeller Balance
Chapter 4
Revision 2.2, Apr 2020
In this example screen shown above, the “Solution” is “32.4g @ 270” which means to place 32.4
grams (g) of weight at 270 degrees from the index point. (see Chapter 2, Analyzer Description on
how to use the Propeller Protractor to locate the phase angle.)
In the middle portion of the screen you see an information line stating “Remove previous trim
weights.” Because all previously installed trim weights were removed prior to the start of the
first run, this is only a reminder for Run 1. This same information line in following runs means to
remove the trim weights installed on the previous run. In other words, the balance solution and
resulting weight installed here after Run 1 may change in Run 2. The weights installed after Run
1 would be removed and new weights added at another location to refine the balance solution.
NOTE
In subsequent runs, all installed weights from each previous run must be removed. The “remove weight”
message will be repeated for every run and solution. Each new solution dictates that the previously applied
solution (installed weight) be totally replaced. In some cases, this may mean removing and reapplying weight
at the same or near the same location. Failure to remove previously installed weight prior to applying the new
solution weight will result in failure of the propeller balance function
.
The next line of text states: “Enter Actual Weight Installed.” In the weight and angle fields
directly below this line, enter the exact amount of weight and the angle, as near as possible,
where it was installed. If you are unable to install the exact amount of weight in the
recommended solution, install a weight as near the suggested solution weight as possible. The
important point is whatever the actual amount of weight is, enter it here. If the solution exceeds
the single location limits of the propeller or spinner assembly (refer to ACES Systems’ Guide to
Propeller Balancing included with your analyzer), you may split the weight across two locations.
If you do not wish to split the weights, press [OK] to continue and then move to the end of this
section, to continue with the instructions at the “Start Aircraft” screen.

– Set Split Weights
To use the split weight option without predetermined holes, press the [F1] “Split Weight” key
from the “Balance Solution” banner screen. The “Set Split Weights” banner screen below is
displayed.
