Hand Launch Sequence
RCdiy March 2, 2017 No Comments on Hand Launch Sequence
OpenTx Lua Mix Script
Contents [show]
Description
Two Step Sequence of Output Values
The script provides outputs to be used as inputs to mixes
The input to the mix starts with an initial precentage value
After a defined delay in seconds the value changes to the second configured value
Messages are played when the sequence starts, stops, is interrupted and at one second intervals during the countdown delay
The sequence and mix line are configured to start and and enable with the same switch in the down/towards pilot position
Example
Hand launch a plane which has a flight controller with auto level
Pilot places flight controller into auto level mode using a switch/pot on the Tx
Pilot starts the sequence by moving the sequence switch down/towards pilot
Sequence starts a countdown with voice prompts in seconds every second
Pilot puts down the Tx and picks up the plane, checks auto level is working
Sequence countdown reaches zero seconds the throttle goes up, some up elevator is added
Pilot hand launches the plane
Pilot picks up the Tx and moves the switch to turn off the sequence
Pilot flies the plane

CUSTOM SCRIPTS Screen
Select this script and configure inputs.
MIXER Screen
Create one or more mixes using one of Seq1, Seq2 as input.
If you want only this script’s values to be used on a channel set Multiplex to Replace.
If 2 channels are not enough select the script again on a different CUSTOM SCRIPTS line.
Safety
The script can affect critical flight controls through a mix.
The mix line must be set up with a switch to enable and disable it. Use the same switch as the sequence trigger switch.
If the script cause any unwanted behaviour the mix can be disabled using the assigned switch.
What happens if a sequence is interrupted and is selected to restart?
The delay timer is reset and the sequence starts again from the beginning.
If during the delay a problem is noticed the sequence can be stopped and restarted from the beginning
