i have a jr x3810 when i mix 2 functions ( 2 ailerons or 2 elevators) i am encoutering a problem with the trim which is only operating master channel and not the slave channel. i would apreciate any help/advise on this matter. thanks

I'm pretty sure that there is one of the mixers that does this. All do not. Best to RTFM.

hi mike thank you for answering i already did yhe mixing of the ailerons but trim only work on one side of the wing i cant make it work on both side

With the ailerons you need to get into the !QUOT!Wing Type!QUOT! part of the programing and select !QUOT!Flaperons!QUOT! If you use the flap part or not. To get into that part of the programing you hold down the 2 buttons and turn on the X-Mitter at the same time. Then scroll thru the functions till you find wing type. Then plug in the right wing servo to the aileron channel and the left wing servo to the flap or Aux 1 channel. If you don't want the flaps to work they can be disabled. It's been several years since I owned that particular JR Radio but I'm pretty sure of what I've told you here. BUT also like I said before you really had aughta RTFM. If you don't have one you can download it from Hanger 9's web site.

The 8103, 3810 in Europe, had 6 mixes. 1 & 2 are multi-point mixes without trim. 3 & 4 are the plain vanilla mixes. 5 & 6 are trinm mixes. If you need the master trim switch to trim both channels, you'll need to use mix 5 or 6.

As has been mentioned, if you are using 2 channels for ailerons, this is built in as a Flaperon Wing Type in the Set-up menu. Plug the right aileron servo into channel 2 and the left aileron servo into channel 6. This will give you ailerons and flaps with trim on both surfaces.

Mike thanks for your advice i am going to check for RTFM but i think that Ed Moorman gave me the right solution. Ed thanks you for your help
