Half of Dual Elevator Ignores Rate Switch

[EvilC57]

Here’s one to tax the brains of all you Spektrum experts.

 

I’m building an F3A type model with split elevators (each half of the elevator has its own servo). This being the case, I’m using an 8-channel Spektrum AR8020T receiver and have selected Tail: ‘Dual Elev’ in the Aircraft Type menu on my NX10, and in the Channel Assign menu have allocated Ch7 Aux2 to ‘Ele’ (Elevator). This gives me control of the left elevator on Ch7, and right elevator on Ch3 as usual - much in the way you would with flaperons on Channels 6 & 2 (L & R).

 

This all works as expected, but with one exception. The left elevator on Ch7 ignores the rate switch,  and is effectively stuck at whatever movement I set up in the Servo Setup > Travel menu. Servo travel, sub trim and reversing all work OK with the channel. And the right elevator works with the rate switch (switch C in my case) as usual.

 

Am I doing something wrong or have I discovered a bug in the NX10 software?

 

Any ideas please?

slave channel 7 to elevator channel 3 should fix it

Hmm I’d wondered about doing that, but it seems odd that you should have to. I’ll give it a try…

Could be a bug, have you tried flight modes and see if it does it in that.

Sorted with a simple ELE > AX2 mix instead. Left elevator now responds to rate switch as it should. I’m still convinced that what I described in my OP is a software bug.

Via another source, I have established that there is a second page involved in assigning Ch7 to the left elevator. It seems that in the Channel Input Config menu I should have gone to the next ‘Rx Port Assignments’ page, and also selected ‘L Elevator’ for Ch7. I have done this now, and the rate switch works on both elevators as it should. And there was me blaming my original problem on a bug! Mix cancelled.
