That's a pretty fancy looking controller....
compared to how things were in the 80's and 90's, this thing is amazing! back in those days they used AM / FM radio waves to control the aircraft; you needed one transmitter per plane and your tx make had to match your receiver make because the protocols were proprietary. these tx are using an open sauce firmware called OpenTX or in some cases EdgeTX, which can be used with multi-module radio hardware that can support the majority of protocols out there from all receivers, or have an external module bay that lets you add more protocol support. further, with OpenTX, the transmitters are programmable and you can store up to or beyond 100 different plane profiles. the new top end tx now have color touch screens, LoL!
I bought the TX12 as it's a 'smaller' tx where as the 16s and 16 Pro are the usual fill size. they probably would work for me and I will buy one eventually, but since I have smaller hands, I went with the smaller tx for hopefully better comfort and ease of use.
I did learn that OpenTX is not synonymous with multi-protocol support though as there are some brands that use it as the firmware for their closed hardware system. the biggest offender with that is FlySky and FrSky. not a big issue if you are okay to be locked into a single brands hardware platform.
overall it's pretty cool and I am excited to get this connected to my PC and start practicing on rc flight simulators. it;'s a lot more effective to crash a plane in software and click a button to restart then having the potential of hundreds to thousands in repair bills.
also, flying is not as expensive to get into like it was in the past. you can get foam airplanes from $50 to sky's the limit, or fee plans you can print out and cut out of hobby foamboard from the dollar tree or Walmart or spend a teeny bit extra and get pre-cut foam kits. check out
www.flitetest.com. the actual expensive part is the power packs...the motor, servos, control horns, guide rods, etc etc etc. OH! a lot of options under $200 are RTF, ready to fly right out of the box. it comes with a transmitter linked to the receiver in the plane so it's it's own self-contained system.
it's so cool!
edit - one more thing. these tx aren't expensive. the TX12 goes for about $120 CAD, with the top end models with color touch screens beeing between $300 - $400. getting the top end models without color touchscreens are anywhere from $200 - $300.
