Your radio is about half-way there.
It looks like it does the same thing as the non-S 8U does. You need two p-mixes to get the rest of the job done.
From your description, servo C is throttle, and servo E is rudder. These seem to be doing the right thing.
A and B are aileron and pitch.
D is elevator.
When you move the collective stick, A, B, C and D should all move.
A, B, D should move according to the pitch curve. C should move according to the throttle curve.
Elevator stick should move A, B, and D.
A and B move together, in the opposite direction to D. A and B should also move half as far as D for a given elevator input.
To get this to happen, mix pitch to elevator at 100% (both directions), link OFF. This should get D moving with A and B for collective input.
The other mix is elevator to aileron. This is set to -50%, with link ON. This should get A and B moving opposite to D for elevator stick input.
The mixes are what it takes for an non-S 8U to do 120 CCPM. I don't know whether the Super 7 has the same mixing capability. The 8U has two free p-mixes in heli mode, and both get used, so you can't have cyclic to throttle mixing or swash corrections. Unless you are using a governor, not having cyclic to throttle mixing could be a problem.
Make sure the A, B, D servos all have the same ATV settings. I think you should be able to use the elevator and aileron dual-rates and expo.
The pitch curve should work normally, but inhibit the hover pitch trim knob. It will only affect one servo, so any attempt to use it will have your Fury flying off in wierd directions.
Also, I'm describing the mixes from memory. I may not have it quite right. The descriptions of the servo movements are correct. You may have to change the directions of the mixes. Don Edberg's book on the 8U has the correct descriptions in it. |
