4DPACK enables backward flight of small EP acrobatic aircraft!

Introducing a PACK that enables backward flight for small EP acrobatic aircraft! Equipped with a 4D ACRO motor gimbal, the thrust direction can be varied up/down and left/right. Controlling thrust direction with the GYA573 gyro and 4D ACRO motor gimbal, combined with the reverse-compatible PSC-15R ESC, makes the dream of backward flight a reality!

Introducing the 4D PACK for Small Acrobatic Aircraft! → See the dream backflight video here.

We’re excited to announce a revolutionary PACK that enables backward flight for small EP acrobatic aircraft! With the 4D ACRO motor gimbal, you can adjust the thrust direction both up/down and left/right, making backward flight possible.

By combining the GYA573 gyro, 4D ACRO motor gimbal, and the reverse-compatible PSC-15R ESC, we bring the dream of backward flight to life!

Key Updates:

• The release of the 4D-PACK includes an update to the GYA553 to version 4.0, making it compatible with 4D flight.
