We would like to introduce you a special limited edition of ten DC/DS-24 transmitters, which was created for the 75th anniversary of the end of World War II. Unfortunately, the release of this series last year was significantly affected by a global pandemic, which also affected our plans. The limited edition is intended for end customers, collectors and fans of JETI and is created in the spirit of flying legends of World War II. Each transmitter has original design, which was artistically painted directly on the transmitter (Airbrush).
You can find more information and photos on our Facebook profile JETI Model.

1. REX Assist v1.19 (03/2021)
Airplane pitch with Assist enabled is no longer affected by acceleration (Horizon mode).
2. MVario2 FAI F5J v2.05 (03/2021)
Supports new sensor revision.

-Time interval of the RX alarm was modified to 2s.
-Extension the compatibility for Futaba R7008SB (S.BUS)
The update can be done by the Jeti Studio.
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.

SPIN Pro 99 opto
The SPIN Pro line offers, in comparison with the predecessors, increased adjustment possibilities, such as automatic motor timing, shut-off voltage adjustments practicable directly in volts, tuning of start-up properties for different motor types, as well as new possibilities of mode activation for setting up autorotation of helicopters.
Opto controllers have galvanically separated input (the receiver signal) from power accumulators, therefore it's necessary to use independent power supply for the receiver and servos (4-5 NiXX or 2-3 LiXX with linear voltage regulator, such as MAX BEC).
