Stick trim
Has any one added stick trim to the standard setup that comes with building a
e-LSA built RV-12. I have Infinety struck grips installed and I ran both the up and down wires up to the panel. I also ran a ground wire to the fuselage.
I did not attemp hook up the trim for the first 40 hours of flight. I am no installing a 496 GPS to use as a backup to the DYNON TOUCH that is installed. Since I now had to open up the instrument panel, I decided to hook up the stick grip hat switch wires.
I thought I could isolate the two wires coming from the trim switch module. I called Van's tech and he suggested pines 18 and 19 were the correct wires. Neither of ohm'ed out.
Can any one tell me how to hook up these two stick trim systems so that they work. I would like to keep the panel trim switch .

Jim,
Try the link below for a wiring diagram from Ray Allen Company. Looks like you'll need the relay deck - available on the Ray Allen website. It's a very small module that can mount about anywhere near your stick wires.

Consider the SkyView AP Panel
Jim -
Before buying a relay deck, consider the Dynon SkyView AP Panel. It can be purchased and installed independently of the Dynon Knobs Panel if you don't want to spend the full amount for both units.
The nice thing about the Dynon AP Panel is it has a built in relay deck. I ran my panel trim switch to the pilot input and the wires from my switches on my control stick to the co-pilot inputs. The pilot input will override the co-pilot input ... so say you were on short final and the passenger trim switch became snagged by a passenger, the panel trim switch is right there by the throttle and will override the unwanted co-pilot input.
A safety feature is also included for protection from runaway trim ... should a trim wire become grounded, the controller only allows the trim motor to run for 5 seconds.
Also there is a built in trim motor speed controller that is user programmable based on airspeed. As an example, one can set an airspeed of say 105 knots ... if the aircraft is going faster than 105 knots, the trim controller will slow down the trim motor, thus making trim adjustments less sensitive at speeds above the user defined airspeed.
Plus, you will have all the other added features the AP Panel adds to the SkyView's autopilot.

Pins 18 and 19 of the switch module are the correct pins. When the panel trim switch is pressed up or down, either pin 18 or pin 19 is grounded. The solid state logic then sends pulse width modulated voltage to the trim motor. If a stick switch grounds either pin 18 or pin 19, then it should work. I do not know what will happen if both up and down are pressed simultaneously.

Agree with Joe you can just splice directly into 18 and 19, enabling the stick switch to ground when pressed.

Yup...works great. If you want both stick grips to be capable, use a double pole..double throw switch to select either pilot or co-pilot grip (you want to eliminate possible cross control).

Stick trim
Sounds like the simple solution is to hook up my wires from the two hat switches on my stick grips to pins 18 and 19.
My confusion in doing this was the inability to ohm check pin 18/19 coming from the trim switch / fuse module.
