Radio System FAQ

What are the differences between an 8U and an 8U super?
  • Digital trim buttons now have a beeper when moved past center.
  • Trainer function now has function/normal modes.
  • Stop watch now has a power-switch ON mode.
  • **FS data direction changes automatically when throttle channel direction is reversed.
  • D/R and Expo are now set individually for left/right and up/down.
  • 5 normal mixes and two 5-point mixes
  • Snap roll function has safety mode
  • *2nd aileron servo programmable so you can use a 5ch radio & twin servos
Helicopter:
  • 4 swashplate types—SWH1 (std) SWH2 (CCPM) SWH4, SR3, SN3 (see SWH FAQ)
  • Offset rate changes with digitrim when function is activated.
  • 3 offset rates now available (8u only had 2)
  • Gyro mixing ("Gx") has normal and condition modes; the normal mode moves to swA automatically when invert switch is active.
  • Governor mixing now available and has normal and condition modes.
  • In condition mode 3 rates are available.

*The 2nd Ail Out feature allows a modeler using a 5 channel receiver to use twin aileron servos. In the past the flaperon function required the 2nd aileron servo lead to be plugged into channels 6 or 7. Now in the parameters menu the modeler can select 2nd ail out to be 5 or 6/7.

**The FS change means that if you reverse the direction of your throttle servo using servo reversing, the computer automatically enters your PCM fail safe settings and reverses the position of the auto-kill for your throttle servo. For example, if you have your FS set to bring your throttle servo to 20% from its base, if the programming did not reverse this when you reverse the servo direction, then your FS condition would be 20% from the top of your stick, or an 80% throttle condition.
