Radio System FAQ
How do I program a four-servo delta wing setup on the 9Z? I want to make the two servos in each wing should act as both elevator and aileron.
To confirm, you want both of the controls on the left side go the opposite direction from those on the right side when aileron stick is commanded, and all four servos go up and down together for elevator stick. The trim levers should work on all four servos for both elevator and aileron trim.
You can't use the default delta setup in the transmitter, as it uses a maximum of three servos, and you want to use four. Programmable mixers will do the job, but you'll have to spend some time working with them to get the trim settings to work properly with all the servos.
The trick is to use both the Flaperon and Ailevator pre-programmed mixing functions.
(The folllowing guidelines are from Don Edberg's upcoming Book on Programming the 9Z. For further information on the Don Edberg programming books, please visit your favorite hobby shop and ask for items from Dynamic Modeling, vendor DMN, or visit the web page at http://home.flash.net/~dynamic3/)
Mixing Example: "Space Shuttle" Mixing (for Enforcer Ducted Fan)
Programming A Four-Control Flying Wing
- Set up the active memory to be in the Aircraft mode. Install your servos in the model, connect to their respective control surfaces, and plug them into the receiver channels listed below:
- CH1 = Right aileron (outboard)
- CH2 = Right elevator (inboard)
- CH5 = Left elevator (inboard)
- CH6 = Left aileron (outboard)
- Turn on Flaperon (FPN) mixing. This will slave the CH6 aileron to the aileron stick. Change the signs as needed to get the proper travel directions (opposite motion with aileron stick movement).
- Turn on Ailevator (ALV) mixing. This will slave the CH5 (left elevator) servo to the elevator stick. If you want the inboard controls to also act as ailerons, use the A-3 and A-4 settings to get proper aileron travel directions. If you just want elevator, set A-3 and A-4 to zero (0%).
- If you want to get the entire trailing edge to respond to elevator, turn on elevator -> flap mixing (E-F), and choose the percentage needed to get the throws desired. Choose sign to get proper direction of outboard control motion.
That's it! Your 4 channel delta wing is ready to fly!
