What might be interesting is that RC transmitters have utilized that general layout format since the 70's. In fact, the company that made that Tx, Airtronics, originally started out as Cox/Sanwa in the late 70's and have been an integral part of RC soaring and precision aerobatics ever since. Since that time RC transmitters have changed only a little in cosmetic appearance to improve ergonomics and switch layout but they have been a "standard" in RC a long, long time. The much later "consumer" drone makers have gone to great lengths to make the transmitters and control functions as simple as possible to attract new users. Our ST-16's are actually a lot easier to get used to. Imagine having to set up each control function before you are able to fly, and adjusting them for a preferred "feel" and accuracy afterwards.
