I´ve the 1W module from BetaFPV and I´m very happy with it. Perhaps the only bad thing is that the transmitter's battery drains very quickly from 250Mw onwards. But I suppose this happens with most modules. I recommend your purchase, a very reliable product.
A fantastically well made piece of gear. Easy to use and program with ELRS 3.0 works great. Recommended.
This ELRS Micro TX Module and Micro pwm 5 ch receiver has proved 100% reliable,even at 100mph speeds ! I flashed them to the latest 3.0 firmware before use. Delivery to UK was also very prompt. Lou Robinson.
