Change Spektrum DX7 to any mode

[monty666]

Howdy. if your wondering how to change your mode 1 dx7 to mode 2 without any real surgery required. just a phillips head screw driver and some needle point pliers.

For instance my mode 1 dx7 had throttle and rudder on the right stick and aerl and elev on the left stick.

take the screws out of the back of the Tx casing, use your phillips head screwdriver to undo the metal friction bar ( which gives the throttle the holding abillity) then remove the spring arm from the aerl elev control by using your needlepoint pliers to gently remove the spring. the arm then just slides off the metal pin.

Remove the brass hex spacer and basically instllall the hex spacer and friction arm in what used to be the the aerl elev control, then re install the spring arm in what used to be the throttle rudder. put the spring in first before trying to atatch it to the arm.


Now the control feels like it is a mode 2 but if you tried to turn your tx on tried to fly your bird it would still be mode 1.

To complete the process press down and select after the Tx has been turned on , scroll down untill you get to Prog.Mix 1

here you assign the controls to the channels!
read page 92 - 95of your instruction book


the best thing is throttle curves pitch curves everything still works brilliantly so no need to wait for the next shipment of mode X its so easy to change .. if you can build a heli you can do this

technically there is no reason you cannot make it mode 3 or 4 as well you may need to fabricate friction bars out of spring steel which should be petty easy

Update!!!

Using my laptop i sometimes touch the touch pad when typing this has lead to a whole paragraph to go missing from the statement above..

to change to made x you need to move the pots around. the pots and trimmer are connected to a little board so you just unscrew it and put it where you need it its a really simple operation just make sure you disconnect your battery before you commence the operation saves a freak short when you drop a screw


THE ONLY PROBLEM IS THAT YOU TRIMMER DIRECTION CAN CHANGE IE UP IS NOW DOWN AND DOWN IS UP

but if your impatient like me and cant wait for the next shipment than give it a go its really simple the wires inside are quite lengthy so theres no extending or soldering required but be gentle as the wire is cheap ass single core stuff that doesnt deal with bending too well so be sure not to bend it sharp or hard.

hope it helps

New update!!!

So i have also just figured out that you may have to do your pitch and throttle curves backwards as now that the pot was inverted your low stick registers as high stick. making your throttle and pitch curves backwards it simple same principles but just think point 5 is low and work back.

Somehow this also fixes the trim function and now down is down and up is up just like normal

The Throttle hold switch also needs to be turned around which is as simple and unscrewing the back undo the hex nut on the throttle hold swith and turning it around that way everything works very normal.

If you have followed the progress so far then you will have a mode 1 controller that has been turned into a mode 2 controller the only thing that is sort of dodgy with this is the fact that your pitch and throttle curves now need to be done backwards (Right to left). i think this is a pretty good result considering no wires has needed to be cut or a soldering iron used its a fairly straight forward process needing only pliers and screwdrivers

the only way i can think of fixing the throttle and pitch curves to go the standard forward (left to right) way is by actually de soldering the pot and hot wiring pin 1 on the pot to pin 3 on the circuit board and pin 3 on the pot to pin 1 on the circuit board. Personally i can live with a backwards throttle and pitch curve it still does the job but is just displayed differently.


COMING SOON

- A Mod to turn the speaker Beep off via a switch as it can be really irritaiting when setting up and going from -100 to +100

- A power mod to run your Dx7 with the standard power pack from spektrum so you dont have to have a battery charged when you play on your sim, This allows you to maxamise your time on the sim and not have to worry about how much battery you have left. This will also be done via a switch
