Transmitter Ex7 switch upgrade - rotary to switch, part 1

Most RC controllers have that one (or more) rotary dial ‘switch’ which for droid controlling, isn’t needed as such, so is just a waste of a switch. Yellow circled in next picture.


Searching up online and YouTube came up with ‘how to’ swap a dial switch for an actual on-off-on switch. Had already bought a switch ages ago, so next was to order a pair of resisters which replicate the potentiometer in the dial switch.

Whilst waiting for the resisters, I decided that rather than buy a pack of switch ‘caps’ or lock nuts, that holds the switch in place, I’d machine one up myself.
So lunchtime in work I found & machined up a piece of aluminium bar to almost the exact dimensions lol.

Just needs a slot added. Original is on the right.
