To modify this setting, click the respective value. Next, input the desired value
directly from the keyboard or via the mouse wheel.
WASHOUT-
This setting determines the amount of twist in the rotor blades. A small amount of
washout will improve the hovering and upright flight characteristics of the
helicopter. Unfortunately, this is at the expense of performance in inverted flight
maneuvers.
To modify this setting, click the respective value. Next, input the desired value
directly from the keyboard or via the mouse wheel.
BLADE FLEX-
This setting determines how much torque is generated per degree of blade flex.
Higher values mean that the rotor blade is stiffer.
To input the proper amount of blade flex, we suggest measuring your existing pair of
rotor blades. Click the more options button (the gray folder with the ellipsis) to
bring forth the Torque options. If known, you may enter the Torque value directly
into the respective value box. If you do not know this figure, G3 will calculate this
for you using the procedure below.
Measuring blade flex:
1. Remove one of the rotor blades from your actual R/C helicopter.
2. Clamp the end of the blade that attaches to the hub to the end of the
table. Use a soft clamp or one with rubber ends to prevent from
damaging your blades. Only use enough clamping force to hold the
blade in place. Approximately 95% of the blade should hang over the
edge of the table.
3. Measure the distance from the tip of the blade to the ground.
4. Add mass to the blade tip (around 100-200 grams, enough to get a good
reading, but not enough to break anything!).
5. Again, measure the distance from the tip of the blade to the ground.
