Transmitter Control

Digital Trims

The ParkZone

®

 4-channel 2.4GHz DSM transmitter features digital trim buttons on all controls to 

make fi ne adjustments. The digital trims are used to fi ne–tune the model’s fl ight path when 
in fl ight.  

Note:

 Before the fi rst fl ight, center the control surfaces mechanically (see Control Centering).

Note:

 When pressed down, trim buttons make a sound that increases or decreases in pitch at 

each pressing. The middle or neutral trim position is heard as a middle tone in the pitch range of 
the sounds. The end of the control range is sounded by a series of beeps.

Dual Rate Function

RTF

This transmitter’s dual rate feature lets the pilot change between high and low control rates for 
the aileron, elevator, rudder.

•  When powered on, this transmitter is automatically in high-rate mode. 
•   Change rate modes by pushing the right-hand control stick vertically into the case until it 

clicks while the transmitter is powered on. 

•   High-rate mode is shown by the transmitter’s LED glowing solid red. In high-rate mode the 

controls can reach their maximum values. This mode is typically preferred by experienced 
pilots for maximum control authority.

•   Low-rate mode is shown by the transmitter’s LED blinking continuously. In low-rate mode 

the controls are reduced to approximately 70% of their maximum values. This mode is 
typically preferred by (and best for) fi rst-time, low-time and other pilots interested in 
smoother and more easily controlled fl ight.
