Note that this is NOT an affiliate link. I get things to test and review because it's fun and I get to play with stuff that I normally wouldn't buy without already knowing that it was worth it. .

On to the transmitter. If you read my review on the T8SG Lite, you know that I hated it because of the sticks. Well, the sticks are far and away the main reason that I love the T12. The sticks on the one that I got are buttery smooth and very precise. So much so that I'm currently in the process of porting all my quads and sail planes over to it. It will definitely become my go to transmitter.

For size comparison, here is a pic of each of my multi protocol transmitters from worst to best. (pic) On a scale of one to ten with one being the toy transmitter that comes with most RTF stuff and ten being a transmitter that I don't yet own , I would rate their sticks as ; 1, 6, 7, and 9 respectively.

Now, I've always been a Deviation kind of guy, and this is my first delving into OpenTx and there is a learning curve you have to go through. That said, I've easily found (so far) everything I've needed online via YouTube and OL's helpful hints. I've got 5 models set up so far and will just keep going (and learning). The hardest parts so far have been figuring out a couple of rogue DSM receivers to get them to bind and getting the endpoints correctly set on my Holybro racing quad (ended up doing it via CLI).

As for flying using this transmitter, the first thing my wife said was that I appeared to be flying more ambitiously, but that's been the case each time I've stepped up to a transmitter with better sticks than the last.

BTW, there is a newer firmware available, but in my first post I'm going to use what came with it...

So...
Pros:
Great stick movement
Programmable with Opentx
Good range
Smaller size, so easier to bring along
Feels good in your hands
Not terribly expensive
Works with my Gforce 1300mAh LiPo batteries

Cons:
Learning curve with Opentx (yep, both a pro and a con)
Riff between the Opentx team and Jumper

I'll be adding to this review somewhat in this post, but mostly in the 2nd post as I mess with the transmitter more.

I'll keep adding to this list...

Voice works fine once you've added the SD Card and have done the SD Card thing!

8 quads and 5 different protocols in so far without a glitch (barring a learning curve with the DSM receivers that came with my Holybros). I've got about 80 flights (I usually refer to this as batteries ) in on the different quads at this point with no dropouts or other anomalies. If you're looking for a multi-protocol transmitter to put all your stuff on... heck, at the price of this thing?? You just can't go wrong with it.
