Safe technology. Do I need this after flying for 35 years? Well The mode 1 for 3D is OK. Mode 2 for pattern and point rolls etc is fine too. The 0 position with the fingers off the stick s I don't care for. Seems to go into a little diving action. I never used the panic button and really don't care too. Fly's pretty good but don't try nany split S's at a low altitude. Trust me.
Enjoy,
