[@alanartt3138]

Great series and just at the right time for me with a new RM here! I didn't have much luck with the firmware update though. Using a Mac here and although it shows the firmware has been flashed when I start again the radio starts as normal with no calibration required and the models are still in the radio. I'm on the latest Firmware so no problem, but will see what happens when the next OTX update comes out.

[@Ard1400]

Great video, cant wait to use my RadioMaster TX16s. Hope is will arrive soon!

[@Retset]

Came just a bit too late for me as I fumbled my way through on Friday! Very slow start (I'm used to Spektrum) but, with the aid of your 12 part series and some fiddling, I am now very comfortable and adding models thick and fast. I'm going to leave my flapped glider, where I want all sorts of modes, to the end!

[@danouski]

So I've received my Radiomaster two weeks ago, i'm a noob though starting on a sim, however I've been every day doing research about this hobby for about 4 months now, and i'm not working. I've installed beta flight, Inav and more mostly thanks to this series and some reading on GIThub. Apparently they are releasing a version in December (same product tx16s) but with colour options and a two hole lanyard, a foldable handle that is longer. However, I have no regrets because the manufacturer is good and they provide all of the parts, great service and they listen to their customers, so I'm pretty sure i can upgrade some of the newer counterparts if i wanted to in the future! ps: great work on your videos, I'm commenting as a part to remind myself to watch some series of your vids such as INAV and some goggle reviews.

These radios are very new so how they will fair over the longer term will only be shown with time.
