Amazing unit. Fast shipping.

This transmitter really is the do it all. I’m using it for all of my spektrum planes. And even the telem. Is working!

Awesome Controller with a couple of easily avoidable and super annoying shortcomings.

For reference, I have the original Taranis X9D and the first X-Lite. This controller is awesome, and could have easily been perfect. Except these two things:

First, the 256MB SD card is insulting in it's size and lack of 'brand name' but even more so in the fact that I literally couldn't format it and unzip the newest EdgeTX sound file zip to it. I replaced it with a Sandisk and had no issues. This is a minor issue compared to the next one, but charge me $5 more and get a brand name SD card.

Second, the AG01 Gimbals are flat-out amazingly solid and precisely engineered, and while not 'better' than the X9D, they are definitely worth the extra cost when combined with the Max, which is why it is infuriating that gimbal sticks scratch up the bottom inside edges of the Max case when the stick ends are fully tightened (which is how they came to me from the factory) and moved to the inside-bottom position. When moved to the outside-top position there is a ton of clearance, but at inside bottom, they scratch up the controller housing, and actually can't even reach full throw. The issue is that the controller itself is tapered and much thicker at the inside bottom than the outside top. How did this pass QA? This is a sleek and amazingly engineered/constructed controller that I literally scratched while calibrating the sticks prior to my first flight. I understand this is a radiomaster issue, and not a buddyrc issue, but someone should be putting different spacers on the sticks, or a warning label not to adjust them to the bottom. Literally every person will run into this issue with the stick ends fully seated.

Best transmitter since my 1976 Kraft Signature

Amazing the new sticks are every bit as good as the Kraft “open gimbal” the feeling of connected is the best I ever felt in over 40 years of RC. The programming is powerful and encourages you to learn more about it. Got the red and love how it looks, the touch screen is very good and quick. Looks and feels very high quality . Decided to get a 2nd identical except blue. Don’t want to have to wait for replacement if lost or broken and price is very good.

Great improvement

The Max MKII is a great improvement from my original TX16s. The sliders are not sloppy and have a definite center detent, and the same for the Pots. The raised grips on the back make the radio feel more secure in my hands. I did have to take the back off to be able to set up the ratchet tension for the throttle, but I had to do the same on the AG01 gimbles when I put them in my other radio. That adjustment can not be done from the front, but no big deal, only took about 10 minutes to do it.

I ordered the 4 in 1 version, as I already have a ELRS module to put in the back of the radio. Now I will be able to fly with just about any manufacturers RXs.

All in all, I am really happy with my new radio and I am really looking forward to getting in a lot flying time with it. It is definitely worth the extra money for the Max version with the AG01 gimbles. This has to be one of the best radios on the market today, and it won't break the bank like some of the much more expensive radios out there. If you are wondering if you should buy this radio or a cheaper one, BUY THIS ONE, you won't be sorry.

Available in 4in1 and ELRS versions 

Here are the tips for you to choose 4in1 or ELRS, reviews by OscarLiang

"If you can’t decide between ELRS and 4in1, I’d probably go for the ELRS version. It’s going to be the major RC protocol in the near future as it’s so powerful and affordable, with a wide range of tiny and inexpensive ELRS receivers available.

One reason to get the 4in1 is if you only want to use other protocols such as Frsky D8/D16, but these are kind of obsolete and slowly phasing out. Or if you are buying an external ELRS module for the radio, then it also makes sense to get the 4in1 as you don’t want to have another ELRS module onboard doing nothing. An external ELRS module might have the advantage of higher maximum output power of up to 1W. But honestly the internal module’s 250mW is plenty for FPV pilots, giving you miles of range in ideal conditions. "

Optional V4.0 Hall Gimbals and AG01 Gimbals


Standard version with V4.0 Hall Gimbals, same chipset as the AG01, optimized hall sensor circuitry, improves center point positioning and temperature stability. Stick travel, self-centering and stick tension are now externally adjustable
