JR 9303 Help Needed

[flyguide7]

I have a PA Edge 540T with split elevators (with a servo operating each side). I cannot figure out how to get each side to actuate together. Right now one goes up and the other side goes down. I am using a Y-harness. Surely there is a way to mix two channel inputs in the receiver to do away with the Y harness and get the servos to actuate in the same direction at the same time.

I called JR tech support and they said I needed a reversing Y harness. But I find it hard to believe that such a sophisticated radio cannot mix the two elevator servos on two separate channels. Has anyone run into this?

You can pick what channel you want to use as the secondary elevator channel.

From the the manual (http://www.jrradios.com/ProdInfo/Files/JRP9240-manual.pdf).

Dual Channels (Wing Type)
V-tail (Wing Type)
A14
1. To assign a 2nd channel to Ailerons, Elevator, Rudder or Flaps, highlight and select INH under the desired channel on the Mate line of the Wing TYPE display and a list of available channels is displayed.
Note: Channels/Switches must be inhibited (INH) in the Devic. SEL function before they will appear in the list as an option to be used as a Dual channel.
1. If the aircraft has a V-tail configuration, highlight INH next to V-tail in the Wing TYPE function and press the Selector until ACT appears. Plug the right Elevator servo into the Elevator channel (Ch3) and plug the left Elevator servo into the Rudder channel (Ch4). Pressing
2. Highlight and select the channel that is to be the Mate (slave) to the control channel represented above it. Plug the 2nd control surface servo into the channel selected as the Mate.
3. If FLAP or AUX3 is selected as a Mate, INH will appear on the Trim Line of the display directly beneath the channel just selected. This means that the corresponding digital switch (FLAP TRIM or AUX TRIM) located next to the FLAP and AUX2 switches can be used as additional trims. However, the additional trims do not function in the same fashion as regular trims. Instead, they trim the controls such that both channels move in the same direction – like reflexing both Ailerons or in the case of Elevator halves, the Elevators would move in opposite directions. As a result, these additional trims should remain inhibited unless there is a special need for them. If changed to ACT, the corresponding trim switch (FLAP or AUX3) will become active. If set to INH these additional trim switches are inactive. Normal trims continue to work regardless of the settings.

Thank you very much, problem solved!

I do not know how a newbie like myself could ever have arrived at that simply by reading the manual :confused: If one is unfamiliar with the terminology with out a little guidance from an informed flying buddy the probability of figuring it out for one's self is slim.

Heck JR's tech support people had no idea! Probably since he does'nt regularly use the product or at least in to that level.

Again thanks for your help.
