Transmitters Flex ECO

Flex ECO is a cheaper option to the popular Flex EX2. It caters to those who only need simple, reliable radio control and who finds the price of Flex EX2 too high.

The transmitters have a rounded design and function symbols on the sides, they are made of durable fiberglass. The transmitter’s two-speed buttons have gold-plated contacts and a lifespan of more than a million duty cycles. They are characterized by safe running, you can clearly recognize their position even in work gloves. Wide choice of symbol sets are included.
