Setting Up SX with JR 9503 TX

I use a 9303 in a tray and I use aux2/ Up is self level, middle is rigid and down is captain rescue, I have a piece of silicon tubing between the gimble housing and aux2 in middle position so when I pull the switch down for captain rescue it springs right back to middle rigid mode, just like a momentary switch. White gorilla glue sticks to silicon and you only need a few drops My middle finger is alway's on that switch when I fly. Here is a close up pic of aux 2 with the silicone tube mod to make it momentary between middle and down position, Works like a charm Moved my flightmode switch to left top of tx and gear is the tailgyro gain with a multipoint mix so I can have different gains for different flightmodes. Switches from left to right on face of tx are flightmode blue, gear red with up position rate mode and down heading hold with gains selected by flightmode, Aux2= SL, rigid and Captain recue red and lastly throttle hold,blue

Well, I don't know how you get Rigid and SL (which I understand is available using the Horizon tab) at the same time when the BD3SX software does not appear to allow that. Did Helicommand?

Of course it means you aren't likely to use this radio for buddy boxing, but so what?

Takes less time than you think,

I've attached a sketch schematic and some photos to show how I soldered the connections between the Gear and Trainer switches (thank you Taos & Magnazan) and programmed GEAR>AUX2 and AUX2>AUX2 mixes. I apologize for the quality of the photographs. It will be obvious to some of you that I don't know what I'm doing.

The 9503 Monitor screen shows GEAR toggling between large 0 and +100 values when I have the Gear switch flipped up; nothing when the Gear switch is flipped up; and nothing either way on the BD Diagnose Tab window.
The Aux2 switch shows no action on the 9503 Monitor screen, nor on the BD Diagnose Tab window.
Please feel free to comment...

p.s. I've got the tail and head gyro gains performing well on my X5. It flies beautifully in Rigid mode. Now to have Rigid and Self-levelling on the Aux2 switch and Bail-out on the Trainer switch! Go ahead - make my month!

Fuggeddabowdit, I ended up using Scott s's Aux2 switch solution. Works for me.
Thanks for all the suggestions.

About the third post Ph7 posted how to use the trainer switch without soldering/ swapping switches. He said he didn't have any Hc3SX experience..... has anyone done this? Works?

Good info, I have a 12x that I am still learning, any one out here using one with hc3sx? I would love to speak one on one about channel assignment

Absolutely great thread!

Dumb question: Why is it so important to have Capt Rescue on a momentary contact switch?

It's not really that important some just prefer it that way. Since I switched Tx I don't use the momentary switch...

[scott s]

While not that important it sure as heck is a LOT more convenient and user friendly!!

That's what I was wondering. In what ways Scott. I have no experience with bailouts. Your solution is awesome, by the way. I like KISS.

This may be true for some but, that switch is almost always located at the back of the TX, and I have small hands and have a hard time reaching it compared to one of the switches located up front. Difference being you just have to be ready to flip the switch back after the save!!!

Not sure which way I will go. I did play with the mixing a bit and was able to use my right side dial (aux3) for the first time. That mix menu is powerful. I'm surprised I never messed with it before.

Rick,
I would put the TX in my hands and see where your fingers fall on it, then I would use the closest or easiest switch for me to reach!!!

Good advice. I'm starting to think the CR should be on the Trainer switch on the left side. It is in the exact spot TH is on the right, its momentary, and its almost a natural response to hit it. Couple wire moves and that would be a done deal.

In think I will use the Aux2 switch like Scott did, but then solder the momentary trainer switch in series with lead to the Captain Rescue side of the switch. The Aux2 switch will be like an enable for the bailout, then the trainer switch will activate it. I may then use the slider on the right to mix in the amount of leveling like hidaven did.
