Transmitter disassembly

[K1RC]

Hi guys a bit of advice needed here...
For my AS project I have to do a product comparison between two items that have roughly the same job but do so in a different way or/and have different processes used to make them. My initial idea was to compare a couple of transmitters, one a KO Propo Esprit III universe as the high end option and a cheapo acoms one. It would really help if I could disassemble these but I still need to use both of them so does anyone know if I can/how to without destroying them? Otherwise I might use a playstation controller or whatever as it does virtually the same job but is cheap enough to destroy and I know people have broken them down... Other ideas for comparisons would be great too, thanks in advanced
