My Feedback: (1)

hello there

requesting assistance from the JETI guru

I have a warbird with pneumatic retracts (2 main and one tailwheel)
and, for the doors, I am using an actuator

I am using two of the Jet-tronic double valves to get the gear and tailwheel up and down

I have programmed the sequencer in

and it has worked


But now, I have ordered, and received an MBAR.

I want to set up a failsafe so that if the pressure gets under 400 kPa, the gear will not go up or, if during flight, the pressure drops to under 400, it makes the wheels come down.

I saw the video from Harry Curzon, and his does not include the sequencer. his failsafe is for only gear without doors/sequencer


this is how he says to do it:


go to

advanced properties
then to telemetry controls

in telemetry controls, add a function and call it "gearfailsa"

then change it to "enabled" and see the check mark
then scroll down and keep it at "Switch"
scroll down and set up the condition X > 400.o +/- O.o kPa
leave duration at NIL
and set default from Nil to 100% then hit OK

exit that page and go back to advanced properties
then go to "LOGICAL SWITCHES"

then add a Logical switch L1, create it and label it "GEARFAIL"
then hit edit and

program it such that :
A) Control 1 is "Mx1"
B) Control 2 is "your actual switch you use to activate the gear up and down"

Condition has to be programmed to : "AND"

then hip OK

then with pressure over 400 kPa, you should see a check mark next to control one and with gear UP, you should see a check at control 2

hit exit

then go to model

functions assignment

and where GEAR is, assign the control to "Logical 1"


however, this does not tie in the sequencer


anyone know what I should do

as it stands, it (the failsafe) does not work


thank you
