Potentiometer based gimbals are normally cheaper and deteriorate faster over time due to friction between contacts. The sticks on a radio are referred to as “gimbals”, they translate user inputs into digital data and control the drone’s movement. But these are either older technology or used in very specific applications, you will learn about these as you progress, all you need to know now is 2.4GHz and 900Mhz. There are other less common frequencies used in RC, such as 27MHz, 72MHz, 433MHz and 1.3GHz. The exact operational frequency differs depending on the region, EU uses 868MHz, while non-EU countries use 915Mhz. Those who don’t fly long range could also choose 900MHz over 2.4GHz purely for its better signal penetration and reliability. The common frequencies used in FPV drones are 2.4GHz and 900Mhz.Ģ.4GHz is the standard nowadays for radio control thanks to its frequency hopping technology, which manages channel automatically to avoid interference between pilots.ĩ00MHz is another popular frequency mostly used in long range flying. Now, let’s get down to the technical stuff and learn about radio transmitters. The TBS Tango 2 is definitely my pick if all you want is to have the most compact radio and only flying multirotors. See my full review of the Tango 2 and how it compares to the Frsky X-Lite Pro. However it’s not great for wing and plane flyers, it doesn’t have enough switches/slider, and there is no trim buttons. Originally it only supports Crossfire (915MHz), but recently TBS added hardware and software support for an external “lite” module, meaning a multiprotocol module can be added to the internal crossfire module so that it can control practically anything, pretty much like the TX16S when it comes to protocols. He said they are way smaller than the full size gimbals on a Taranis X9D. Note: my friend Giovanni who owns the Tango 2 disagrees with the product description which claims to have full size gimbals. And it’s made by TBS – the brand you can trust when it comes to quality. It runs OpenTX, has built-in USB charging. It has built-in 900MHz Crossfire module with a maximum output power of 250mW. According to TBS, the Tango 2 has high quality full size gimbals that have fordable sticks (only in pro version), which is great for transportation. It’s extremely portable and yet with great ergonomics. I’d recommend getting the Crossfire module with this radio. The full size hall sensor gimbals gives you full range of stick travel and excellent precision. It has a multi-protocol module inside that supports almost every protocol in the hobby, and it also fully compatible with Crossfire. In my opinion, the most versatile and best value radio right now has to be the TX16S. If you are looking for a compact radio and you have the budget, I’d probably recommend getting the TBS Tango 2 instead (explained in more detail further down this article). But it’s hard to complain for this price! See our review of the Jumper T-Lite for more detail.Īnd because it’s so cheap, DO NOT expect top notch build quality. The main limitations would be the lack of switches. It’s very small so you can take it everywhere. It supports FPV simulators so you can get this to practice flying before even building a drone. This is the cheapest radio ($67) that runs OpenTX, has multi-protocol module built-in and supports external module. Radio Recommendations Cheapest Worth Having However, I encourage you to do more research and check out reviews on the radios you like before deciding. Too many choices right? Well, here are my recommendations below. Here is a list of all the popular radio transmitters on the market currently.
