I have a couple of old transmitters that I am thinking or connecting back to my kit. I am not paying £50 for someone to use a screwdriver.
I know the battery size, not sure about the o rings. I think the sizes are 25 mm x 2mm and 9.25mm x 1.78 mm. Does anyone know for sure?
Is there anything to beware of, such as being careful with the screws, which I suspect are self-tapping?
