IMPORTANTE NOTE FROM RADIOMASTER - APRIL 2026

Due to ongoing global supply chain constraints, flash memory chips have experienced significant instability in supply along with large cost increases. Despite the best efforts of our procurement team the supply remains the highest concern and poses a genuine risk of production interruption that could halt manufacturing of these transmitters. 

To ensure continuous and stable production, and to avoid any disruption toyour supply, we have made the difficult but important decision to change from 4GB to 512MB in the TX15 series and TX16S MK3 series transmitters ordered on or after April 3, 2026, with corresponding product SKUs updated accordingly. While today’s price of 512MB flash units is now above the initial price of the 4GB flash units the 512MB flash units remain stable in supply. We will absorb the increase and this change will allow us to retain the current retail price and dealer margin while helping to reduce risk of production disruptions. 

Mass production orders with this configuration change are expected to be delivered around late May 2026. During the transition period between the old and new versions, there may be mixed shipments of products with different memory configurations from our warehouse. We kindly ask all partners to take note of this and to communicate the change to end customers in advance. Orders already placed will retain their originally memory configuration. We sincerely apologize for any inconvenience caused by this adjustment. Thank you for your continued trust and understanding. If you have any questions, please contact your business representative.
