The MEZON PRO controllers are a successor of the previous product line of the Mezon speed controllers. They contain a lot of new features and improvements, such as comfortable configuration via the JETI DC/DS transmitters, proportional brake, bidirectional motor operation, EX Bus configuration etc.
MEZON PRO controllers are available in OPTO, standard (BEC) and LMR versions.

Lots of new features have been included in the latest updates for standard REX and REX Assist receivers:
Duplex REX Assist V1.10
Comes with a lot of fixes and enhancements. Horizon and Training flight modes have been optimized, introducing 2D flight mode. To see a full list of features and modifications please visit the release notes.
Duplex REX V1.12
With EX Bus backup and signal forwarding.
All updates can be handled easily by JETI Studio. Please download the latest device definitions to your transmitter (simply update the transmitter to V4.28 via JETI Studio, the necessary files will be downloaded automatically).
AC Speed Controllers
Controllers that do not have BEC are marked OPTO, and require the use of a receiver battery (4 or 5 x NiXX), or an external BEC (Jeti MAX BEC is recommended for use with up to 12 cell NiXX, 3S LiPo, or 4S A123). OPTO controllers are designed to provide complete electrical isolation of the power supply from the radio system. OPTO controllers are recommended when BEC circuits are not sufficient for your needs because of a high servo count, the use of digital servos, or for models with high current consumption or high operating voltage.
