RE: Flight Modes and throttle trim
Yeah, digital trim for turbines is a real pain, so don't use it.
I use switches 28-29-30 to replicate the trim/Aux function.
First set all Throttle Trim Steps to 1 - unfortunately, you can't set it to zero to fully turn it off. Center thethrottle trim to 0and leave it there.
In Sw Assign set Sw 28 to TH-CUT- I also assign Button 32 to Throttle Cut as an alternative emergency off function
Set TH-HOLD to Sw 30, I also "AND" this to Sw 22 so it's only active gear down.
If you also want to use the Low Idle function of a JetCat engine, assign IDL-DOWN to Sw 22 AND 15 or whatever. I do it that way so I get a lower idle when the gear is down with full flaps.
I have TH-CUT set to -120%, IDL-Down set to -40% & TH-HOLD set to -70% all set to COM so active across all flight modes. All based on Throttle EPA set to L100% - H100%.
Your numbers may vary.
The result for JetCat is Sw 28 & 32gives throttle off at all times. SW 29 is the RUN position, and SW 30 is the higher rpm for cool down.
So move the Sw to 29 to start & run, move the Sw to 30 for cool down and back to 28 for Off and never touch the throttle trim.
