Product Function

Belly mount

By using the ET-support, the mounting center of gravity is placed on the belly mount, which makes the hanging weight more stable.

Mount detection

There are four mounting positions in unlimited order, which automatically identify the mounting position, and the pilot app displays the mounting status of each position in real time.

Arbitrary delivery

Through the pilot app control, control the independent delivery without limiting the order, that is, click to launch. It can also be cast with one key, which is efficient and fast.

Manual hanging

Materials can be mounted and manually released without power on.
