RadioMaster is pretty much a jumper clone. Have you got your new T18 yet? I'm loving my T16 Pro. Looks nice, feels nice, gimbals are very smooth, and so powerful! I can do anything I want! Right now I've been having fun with flaps on a slider so they're infinitely variable.
I disagree with the term clone, the Radiomaster is more of an evolved version of the Jumper T16. Part of the original jumper development team broke away from Jumper and formed Radiomaster and in so doing improved the original design to eliminate a lot of the faults and design flaws of the early jumper T16 model, Jumper still haven't resolved charging the battery in the transmitter.
I have been using the Radiomaster for some time and have finally settled on FRsky receivers as my preferred choice, the X6R and X8R give you basic built in telemetry eg RSSI, but they also enable you to add additional stand alone telemetry modules via the SPORT connection. You can pick up an X8R 8ch receiver with SPORT and SBUS for around £30 (that's GBP).
The S6R and S8R don't have telemetry but do have built in 3 axis flight stabilisation, there is a specific option on the Radiomaster so you can set this particular receiver up via a simple set-up process (the S8R's sell for around £35).
I also like using Flysky receivers as a cheaper option (£10 - £12), they can be a bit on the bulky side and I don't like the antenna shielding but they are reliable and cheap. I have a few of Radiomaster's own receivers, they operate on the D8 protocol which is basically FRsky's operating system. They too are cheap (£10 - £15), but are more discrete and light weight than the Flysky receivers.
As for Spektrum receivers I still use them reluctantly, I have personally have reservations about the reliability of them these days. However, I will leave it up to you to form your own opinions. I have tried a couple of the V710 Spektrum storm 7ch receivers and for the price, they perform like genuine Spektrum DSMX receiver and the range appears good.
