Hi Craig
I really tried not to type an essay, but I failed. Please forgive...
7 channel TX/RX combination has the 4 'standard' channels (throttle, rudder, aileron, elevator), plus pitch and two auxilliary channels. The two auxilliary channels, if I remember correctly, are channel 5 (gear) and channel 7 (gyro gain).
On my JR set, and you'll find the same on your DX7, the channel 7 (gyro gain) can be used to set the gyro gain depending on the flight mode switch - thats the one that has normal, idle up 1 & 2 on it, on the DX7 at least. *
As a channel is merely a way of telling a servo where to come to rest and the gyro uses this as an indication of where to set its sensitivity, its technically possible to put the gyro on any channel. You could even put it on a y-lead and connect it to your aileron channel, although it would make for interesting flying - ever time you move left, you'd go into HH and the more left you go, the higher the gain will be. Right, and your in non-HH etc.
So, its technically possible to use the 'gear' channel to do the gain on your heli, as I've done.
With regards to your scale fuzz, no, you would still leave your gyro on Ch7 and plug your retract servo or servos into Ch5, as its channel 5 thats switched (on the DX7, at least) by the 'gear' switch.
Make sense?
======================================
* If you're sure what I mean by the fllight mode, please skip this paragraph: heli's can be flown in 2 differnt 'modes': normal is used for hovering and normally means that when your collective stick is full down, you've got zero throttle and, in your case, about -2 digrees pitch. This is what most people use to learn on, as pulling the throttle back stops the motor/engine
In 'stunt' mode, most people program is so that at zero collective stick, there is maximum negative pitch and maximum throttle, and at full collective stick, there is maximum positive pitch and max throttle. Mid stick is zero pitch and about 60% throttle, depending on engine. Stunt mode is what all the 3d pilots fly with, as it allows one to hover inverted etc. Idle up 1 and 2 are merely variants of that, with either greater pitches, higher head spend, gyro gains etc.
The 'Throttle Hold' feature is not only used for practising auto's, but also for when crashing while flying in a stunt mode. As you know, throttle hold mean zero throttle, and what-ever pitch you program in using the respective pitch curve. So, if you're about to crash in Stunt mode, hit the throttle hold switch to stop the engine while still having full collective control.
BTW, have you ever hear of the 'funky chicken' manouver? Thats when you crash in stunt mode and forget to hit throttle hold. The heli lies on its side and thrashes itsself to death and the engine still turns the rotor.
