Control transmitters

A control transmitter (TX module) is an external or internal RF unit of the pilot's radio controller, responsible for generating and sending commands to the quadcopter's receiver. The Astreia Tactical online store features the most powerful and reliable long-range modules based on advanced protocols such as ExpressLRS (ELRS) and TBS Crossfire. Thanks to flexible output power settings (from 250 mW up to 2 W and beyond) and optimized data packet transmission algorithms, these devices guarantee phenomenal flight range, ultra-low latency, and a rock-solid link even in complex urban environments or under active Electronic Warfare (EW) interference.

Our assortment covers transmitters in popular form factors like Micro (standard JR Bay) and Nano (Lite Bay), making them fully compatible with the majority of modern radio controllers (RadioMaster, Jumper, TBS, etc.). Depending on your tactical mission, you can choose modules operating on 900 MHz (868/915 MHz) for maximum signal penetration and extreme long-range flights, or high-speed 2.4 GHz versions that provide lightning-fast response times perfect for dynamic freestyle. Modern TX modules are also equipped with active cooling systems, preventing overheating during prolonged operation at maximum power output.
