# example airshow in a loadable file
# to use the airshow put the file on your microSD in the root
# directory with name trickNN.txt where NN is the command ID you want
# to assign. The trick can then be used in auto missions or in
# TRIKn_ID commands for tricks on a switch

# you can use name: to give your sequence a name
name: SuperAirShow

# you can add new path functions, following the same syntax
# as in the main plane_aerobatics.lua
