Yes it will work with any servos.

I tried four major sources to buy DX-7 package with MODE-1 transmitter, they all have only MODE-2 plently in stock. Will I be able to swap the gimblas and make it Mode-1 in DX-7? Or should I wait for another month till Mode 1 stocks arrive? Is it only the gimbals or switches swapped as well?

Thanks for your response

My Posts This: Topic  Forum		From what I read on another forum there is more than meets the eye to converting and voids warranty. I would wait myself, good luck.

My Posts This: Topic  Forum		I too am waiting for a mode1 DX-7. If you can get one from AUS then you're in luck. I think we will need to wait until they get shipped to the USA. The process of changing it over is not feasable for anyone but the tech folks at Horizon.

I tried four major sources to buy DX-7 package with MODE-1 transmitter

I've run across some confusion about stick modes when making inquiries and requests about this. Are those of you seeking Mode 1 DX7's actually looking for tx's where BOTH gimbal's functions are reversed? In other words -- left stick = elevator & aileron (cyclic) and right stick = thottle/collective & rudder?

If so that's actually Mode 3, what I also fly.

It seems the confusion arises because a Mode 3 tx probably starts out as a Mode 1 tx (left stick elevator & rudder, right stick throttle & aileron) and then has its rudder & aileron functions swapped electronically to make it Mode 3.

There's apparently a style of plank competition in Europe and elsewhere where Mode 1 (or Mode 4) provides some control advantage, but heli pilots everywhere will naturally want their cyclic controls on one stick (Mode 2 or 3).

I'd sure like to get a clarification about this from Mr. Beard or someone at Spektrum. Adams told me via PM that Mode 3 is not possible on this tx.

My Posts This: Topic  Forum		I would think you could just move them...

if the left stick is the right and the right is the left... could not you just swap the locations physically?

I guess it must be more difficult than that or they would have thought of it.

My Posts This: Topic  Forum		That's certainly possible, with the worst case scenario probably being that some pot wires might have to be extended and the trims & trim indicators would no longer correspond to the sticks, but I'm guessing Adams made an honest mistake in telling me Mode 3 wasn't possible.

A couple Service Menu button pushes should be all that's required to change a Mode 1 tx to a Mode 3.

Since I fly Futaba all the servos have tabs so what I did was to cut some slots in the case because I don't like cutting the tabs off the Futaba connectors. Besides I didn’t know if I was going to like the radio enough to leave it there and I didn’t want to end up with a bunch of tab-less connectors.

How did you make the slots (small saw blade; exacto blade; dremel)? Did you remove the case while cutting?

My Posts This: Topic  Forum		I have a better remedy - Buy a bunch of JR plugs to replace all your silly Futaba plugs then your servos will fit anything you wanna plug 'em into.

I am considering this so I don't have to shave off the tabs on my servos.. plus I think the tabs give better orientation...

My Posts This: Topic  Forum		Re hacking the DX7 to do a mode change, you can move the stick wiring , switch wiring etc BUT the electronics will still stay in the mode is it set to. So, although you move the digital trims physically when you adjust them, the display will shoe its original location. ( ie adjusting a right sided trim and the left trim display will change on screen)

This is one of the reasons that Modes 3 & 4 are NOT available on the 10X.

(To carry out a stick mode change requires new firmware to be loaded.)

My Posts This: Topic  Forum		why...

if the sticks are just flip flopped.. why need firm ware change..
if you put 10 ft of wire on the gimbles and held them in any attitude they would work.. thats is what mode three is.. the right gimble on the left and left gimble on the right.. the progam could care less of actual position. ya move the collective stick up and collective increases.. 10 ft away or in the right side.. no matter.. but you would have to physically move the gimble.. not program the change.

My Posts This: Topic  Forum		I read on RCGroups that the DX7 is not capable of mixing (combining) DR swithes. Does anyone know if you can change Idle up modes, pitch curves, and gyro rate settings with one switch? I'd have to flip multiple switches where previously, I only hit one switch. A few months ago this wouldn't be an issue but I've grown pretty dependent on these 9C functions. If the DX7 is not capable of this function, I may have to wait until the Futaba 2.4Ghz module becomes available.

Yes, the idle up switch takes you into different throttle and pitch curves, you cna also tie the Aux and gear channels to the flight mode as well. SO YES, you can tie all those functions to the single switch, just like most heli radios.

My Posts This: Topic  Forum		better yet, some folks have been able to swap the pots and leave the gimbles in place. You are right that it should not matter to the programming. There are the trims to consider as well, that makes the job much more difficult assuming you were able to move the gimbles/pots without having to physically modify the radio case. (having the trims show in the correct location on the screen would require a programming reflash) The nice thing is that there is mode1 Tx's already available, just not in the USA. They should be here soon though. I am considering the idea of asking a AUS dealer if they would be willing to swap straight across for a mode2 DX-7. I would pay USA prices for a mode2 and send it to them. They certainly have a few people in AUS looking for mode2 that cannot get them locally. They could send me a mode1 and since the swap is for the same package I would not have to pay any extra other than shipping. Modes 3 and 4 may become available if there is enough demand for them as it should only require a program developed for them.

My Posts This: Topic  Forum		midwest, its the display that cannot be changed... if the display is set so that the rudder trim display is on the bottom left, then no matter where you put the trim switch, the trim position will always be shown in the bottom left of the display.

My Posts This: Topic  Forum		Pyrock,
Unfortunately, even if all of Mr. Drew's claims come true, a 9C plus the XPS system will still be behind the power curve in terms of latency. Having been a 9C owner, I really don't see the DX7 as having all that much less programmability than the 9C.

My Posts This: Topic  Forum		Screen...

yes you are correct there.. I did not think of that... but if I flew mode 3 I think I might live with the trims showing backwards so I could have the radio... I really don't look much at where they are after set up anyway.. Trim while I fly... looking at the screen at that point would be bad
