In order to make it possible to compare tests conducted by different pilots—and given that we have no control over the weather—we aim to standardize the testing procedure.

Some important points:

1. A speedometer and variometer are required for testing. If possible, please perform the tests as shown in the form.
2. RPM should be measured on a warmed-up engine.
3. When measuring ascent, the best and safest method is to transmit parameters to a helper on the ground via radio.
4. If it is not possible to record the time of ascent, it is worth doing at least a trial with recording a stable reading from the variometer during a prolonged ascent in atmospheric conditions and low wind. All measurements should be started at as low an altitude above the ground as possible (about 50 m) and a low geographic altitude
5. If you have access to a dynamometer it is worth measuring the static thrust.
6. To record test results, it is a good idea to use the appropriate form.
7. Remember that comparing propellers only makes sense if they are propellers with the same diameters and number of blades and the measurements take place on the same day. Due to changes in pressure, humidity, temperature, even measurements from another time of day can be falsified.

1. Rotation max on the ground
2. Rotation for horizontal flight
3. RPM max on climbing
   1. At trim speed (Trimmers engaged, rudders released)
   2. At medium speed (give configuration of trimmers, speed/power attack)
   3. For max speed, (max trimmers and max speed)
4. Average ascent at max speed for the following speeds at an elevation from 50m to 150m (timed start /50m/ and stop /150m/).
   1. Trim speed (Trimmers engaged, rudders released)
   2. Average speed (specify trim configuration, speed/power attack)
   3. Maximum speed (max trimmers and max speed)
