RE: European radio
Somewhere I read it's an aluminium frame and some sort of plastic face. Since there is only a small market for Jeti, a very expensive casting mould was out of question.
Having the display on top has some advantages. But it's a pain when programming the transmitter/model since the buttons are on the other and of the Tx. IMOO, the best approach is having the display and programming buttons close together or a touch screen.
Also, if you like to use telemetry in flight, even looking at a display mounted on top can cost you a plane.
