JR Radio Set-Up for Aerobats

Setting up channels and servo control using JR transmitters in this case DSX9 (2.4ghz)

JonTappin wrote: Except 2nd aileron should always be in aux1/flap (whatever your radio calls it) channel. As you have JR, there will be a dedicated dual aileron function (10X calls it 'wing type') which you can use to set up differential, flapperons etc. If you use any other channel you would have to set it up manually.

Use the next available aux channel for your second elevator, some of the higher number aux channels can have a noticable lag when mixed to other channels. Easy enough to see this when setting up.

When you are setting up the elevators, it is worth spending some time making sure they track together across their full range, not just at neutral and the end points, when you only do the extremes, you would be surprised how much out they can be at the mid points. Tape a couple of lengths of balsa to the elevators 3-400mm long, with their outer ends together behind the rudder, you will then easily be able to see the tracking. I use a curve mix instead of a standard one, you can then adjust at points throughout the travel.

I have changed the setting in the "device set-up" menu to dual/mate. This now gives me new list showing aileron l & r and also elevator l & r. There is now a aileron differential setting too. So far so good. I have inhibited aux2 switch (flap) and also gear switch. At the moment I am just using the "monitor" facility to see what changes are having what effect.

Do I still need to use the programmable mixes for basic functions of aileron and elevator?

I am not familiar with the programming for the DSX 9 however it sounds like you have dedicated set ups for 2 aileron and 2 elevator servos, you should not therefore need to use any other mixes. Unless you need to fine tune the elevator tracking as I mentioned in the original post above.

Are you sure that the second elevator channel you should be using is the gear channel? I would think it would be more likely to be the next available aux channel, aux3? When you move the elevator stick, can you see another channel moving with it on the monitor? Your tx instructions should tell you which aux to use for the 2nd elevator if all else fails.

Jon, in device set-up I have enabled dual/mate. Disabled flap and aux2 switches. Now in the list function menu I only have options to mate aileron with aux2, not aux1 though. I might still have that channel assigned somewhere. Elevator can only be aux 3 or 4. I also have aileron diff available now. I'll keep fiddling for now.

Just go with the options it offers, are you sure aux1 is not the same as the flap function?

Reset TX and started afresh. In wing type selected Dual/Mate. Now have the option of using flap (which is aux1) to aileron, elevator mated with aux2. Aux3 and 4 I have left unassigned but as per my Mustang I may use aux4 as remote "kill-switch". In the list menu I now have aileron diff available too. I have only been viewing the Monitor at present but will shortly plug in the model fully to see what happens.

Sound like you have it cracked Phil.

Rather than using a throttle trim cut, I would recommend that you consider an elecronic ignition cut remote switch. I run these on all my petrol engines, they allow you to cut the ignition power via the tx and are a good safety feature. I have used the RC excel one which is about £15, see the attached link, scroll down to the bottom of the page.

I notice in an earlier post Phil states he is connecting left aileron to ail (ch2), on my JR Tx, a 9X, when I select the appropriate wing type, the servo list shows ch2 as right ail and 6 as left ail. I adhered to this so that all other adjustments appeared where I expected them. Maybe the later Tx's are different?

I think you misread my setting for ignition kill. On the Mustang DLE20 the Opto Kill switch is connected to aux4 (which is assigned to trainer switch) and then set the range to 100%, and now when lifting trainer switch theign ition can be cut remotely. Steve M set this up for me on the TX and then I tried it at home and it works. So I was just following this set-up for the Cap232

That was how I originally set it up but I don't think it matters which channel they are plugged into if they are mated. I suppose! Except if your in Glider mode and then all channels are reassigned internally.
