Need Channel for Landing Gear

I built a scale heli, and I'm using the Spirit GT.
How can I free up a channel for my electric retracts? I bought a Spektrum AR6610T, which is bound and working. But, for my life, I cannot figure out how to free up a channel for the gear.
The Gyro is using the gear channel by default. The BING/PROG port on the AR6610T is connected to the RUD/ELE on the GT. So, I have five free channels on the AR6610T I was hoping to use for the gear.
Tips? Tricks?

You may need to re assign the switch you like to use for the retracts to another free channel. This should be done on the transmitter this is how I do it on FrSKY ethos transmitter.

Hello,
one trick you can do is to deactivate the gyro-Channel in Spirit Settings and make your settings directly in the FBL -
second trick is to use under special functions an dedicated output to switch your gear - I am not shure there are two possible channels which can be taken, please look in the list...

Assign F: Output to AUX2 in the channels window and select a free channel there. You can use for example channel 10. Then connect landing gear to AUX2 port.

Can I do this even with the BEC cable plugged in to AUX2?

Yes, or you can use CH0 port as well.

I tried CH0 and mapped it in "Channels." But, it won't toggle. It simply says (State 1) and on. What am I doing wrong?

ZeXx86 meant: BEC to CH0...

I meant F: Output to CH0 instead of Output to AUX2 if it is unused.
But both should work, also BEC at CH0.
There is nothing else needed. It should work immediately with a servo.
You can also assign Throttle function to Channel 1. This should do the trick.

When I set Output to AUX2, I don't see the usual "Value 0/1"; I see "State: On (1)." In this mode, the value doesn't toggle like other channels.
I got the gear to work by disabling and using the Gyro channel instead. But I'd like to learn the way you suggested, too.
What have I done wrong?
