I am just reading this thread now. I fully agree the best option is radiomaster with edgetx software, and elrs. I have been flying with elrs for 5 months now and have not had a signal loss. The downside of elrs is that it makes some demands on the user. It took me a while to learn to use configurator, to flash tx modules, and rxs, etc, but the good thing is that people like John (the guy in the "5 things" video above), Joshua Bardwell, Andrew Newton , Painless360 and other commentators have posted videos on almost any issue you are likely to encounter. I agree with these folks that elrs with edgetx has the most advanced telemetry, the best RF protocol, and advanced features like dynamic power (dynp). When the tx detects a signal failure (from monitoring RSSI, Rqly which is valid packet rate, and signal to noise) the dynp feature increases your tx power from say 10 mw or 25 mw to 50 or 100 mw. I set up my tx so I am informed whenever dynp increases the power. In my experience it always returns to base level within a second. My impression is compared to my local oval, Mc Coy field has alot of activity on the 2.4 band from neighboring industries and that affects signal to noise.

The radiomaster txs (I have a tx12 and a Tx16, both are excellent) required me to convert them from mode 2 to mode 1. RM say their tx16 v2 can be converted without opening the case, but despite meticulous attention to the detail in the video by RM, it did not work for me on my new tx. I complained to RM Australia and they opened a ticket for a service at Mantisfpv at North Parramatta, who then did the conversion to mode 1 without charge. Mantisfpv have a setup service and will fix any elrs or radiomaster issue.

The one antenna elrs rxs that come wth pwm pins by betafpv and radiomaster work fine, but John prefers the 2 antenna true diversity Matek r24d rx, which I am now moving to. (I have surplus 1-antenna rxs if you contact me). Matek has the reputation as a top elrs rx brand. The r24d and most elrs rxs require you to solder pwm pins on the rx board, or to attach a pwm converter board. I refuse to solder on circuit boards as I am a crap solderer, and I pay fpv stores like Mantisfpv and Rising Sun to do the necessary (you do not need to buy the rx or converter board from them). I always add a lead (a single wire) that goes from the vbat terminal on the rx or converter board to the red wire of the lipo balance lead, and allows you to monitor lipo voltage during a flight.
