TRIM submenu: Resets and adjusts effectiveness of digital trims.
HELI models only: OFFSET is available in the idle ups. If OFFSET is inhibited, adjustment of the T
trims for all flight conditions. If OFFSET is active, then moving the trims within any one condition will affect only that
condition. See OFFSET, p. 70.
Trim reset (CLR): Electronically centers the trims to their default values. Note that the SUB-TRIM settings and the trim
STEP rate are not reset by this command.
GOAL of EXAMPLE:
Reset trims to neutral after having
adjusted all linkages.
NOTE: This is one of several
functions for which the radio requires
confirmation to make a change.

Trim step : Changes the rate at which the trim moves when the T
units, depending on the characteristics of the aircraft. Most ordinary aircraft do well at about 2 to 10 units. Generally larger
trim steps are for models with large control throws or for first flights to ensure sufficient trim to properly correct the model.
Smaller trim steps are later used to allow very fine adjustments in flight.
GOAL of EXAMPLE:
Double the sensitivity (larger step) of

flight of an aerobatic model to ensure
sufficient range to trim the model for
level flight.
Where next?
The 7C has digital trims which are different from conventional mechanical trim sliders.
