Specifications

For most transmitters, there are only two differences:
• An airplane version will have a ratchet on the throttle. A helicopter version has a smooth
throttle with no ratchet.
• An airplane version has the idle-up switch on the right side, and the throttle hold switch on
the left side. A helicopter version has the idle-up switch on the left side and the throttle hold
switch on the right side.
For Futaba transmitters, there is no firmware difference betweeen the airplane and heli ver-
sions of the transmitters, so the two physical differences are the only difference.
Some JR transmitters have separate airplane and transmitter versions where the airplane ver-
sion does not support CCPM modes. The JR transmitters known to have this problem are:
• JR XP783 airplane (CCPM unlockable via service menu)
• JR X-388S airplane (CCPM unlockable via service menu)
• JR X-347 airplane (CCPM unlockable via service menu)
• JR 10X airplane (CCPM not unlockable)

28.2.2. Can you give me your transmitter settings for helicopter X?
This is a meaningless question, because the transmitter settings for a helicopter are depend-
ent on:
• Servo type. Different servos have different ranges of movement.
• Servo horn type and hole used. If the servo horn is not exactly the same, and the same
linkage hole used, then the range of motion will be different.
• Servo rotation direction. Different servos have different rotation direction
• Linkage length. The settings will be different depending on the length of the the linkages
from the servo to the swashplate and from the swashplate to the main rotor blades and the
flybar.
• Transmitter type. Different transmitters use different ranges for servo movement
So therefore, unless all of these different factors are exactly the same as your helicopter, the
transmitters settings will be significantly different.
28.2.3. Which receivers are compatible with my Walkera transmitter?
None of the standard receivers from Futaba, JR, Hitec, Airtronics, etc are compatible with
Walkera transmitters.
28.2.4. Which transmitters are compatible with my Walkera receiver?
None of the standard transmitters from Futaba, JR, Hitec, Airtronics, etc are compatible with
