Bird mode F16

This craft is a F16 with a bit of difference which is THE BIRD MODE
this mode makes the jet wings like a literal real bird wings it makes them flap around like a bird and the thing that helps that is the light weight the jet is only 5 tons which is insane for a jet while in bird mode the craft can fly with only the bird mode no engine needed.
there are some issues though which is once you turn on bird mode it cant be turned off because i dont know a lot of vizzy coding if you can fix I'd appreciate it
to start flying
turn on the engine wait a bit until you see the afterburners after that just hold the pitch down and its gonna be quick to fly less than 10 seconds
then when your in the sky you can turn off the engine and turn on bird mode to become a BIRD
if any issues are found please consider telling me through the comments
and have fun.
