Another Pros :

1. You can fly during 100 hours without charging your EW logger
2. "After Sale" service is just excellent ! Top quality about
communication with vendor.
3. Very light.

Another cons:

1. There is no standard "ON/OFF" switch. You have to click twice (at a
certain speed) on a very small button and see the red light
disappearing for switching off the unit.
2. I have to admit and confirm that the antenna connector looks (and
is ???) very fragile.

Recommenation:

Buy the EW unit with a SD card reader. So you can leave the EW inside
the cockpit and bring only the SD card at home.
