I have a Vertical Power 200 in my RV-10, and it has runaway trim built in as well
as trim speeds. Not sure if the VPX still has it.

For what it=99s worth, I just have the Ray Allen system but with the r
ates being high for faster airspeed and potential for runaway trim I put in a
trim disconnect switch on the panel I can slap before it gets too bad. Not a
s quick to respond as the systems in this thread, but cheap and effective.

I have VPX. I used use its trim controller. I rewired since then to use the
Dynon autopilot control panel's trim feature with auto-trim.

Sir Tim, Thanks!
I did see that and read your write-up. I don't have a flaps up switch but
will add one per your suggestion.
I do have a flap position potentiometer that is used to show the flap
position on the EFIS.
Thanks, Jim C

I figured it out.
For those who encounter this issue, it was the Epson printer driver.
I have a label printer attached to the kitlog computer. When the Epson print driver
is installed, kitlog will not generate reports. uninstall the driver, kitlog
works fine.
I can have one or the other but not both...very annoying!

I've had run-away trim. I was on downwind in a Piper Arrow when the nose
started to pitch downward. I looked and saw the trim wheel spinning away. I
grabbed it, which is the response in a piper, while the CFI with me pulled
the breaker. Retrimmed and landed normally.

Glad you had a good outcome. Bad timing on the approach.
