Description

This is more of an idea than instruction how to do it and doubt that no one will print this :)

Faced with dilemma; how to flash 9+ SiLabs ESCs with minimal work. Flash pads are O ?1mm 1.5mm apart so normal spaced contactors won't do.
For a self-made flash tool, spring loaded contactors are a must (and I really really wanted them) so search began.
Finally found suitable, sony ericsson Z600 SMC battery contactors. They are 2-1-2 and 2 are damn near that 1.5mm but the middle 1 was not -> saw that %#&!er off and glue it closer -> DONE

Why I expect this to work for most ESCs, is that it's said that the pads are near always at same order.. (https://github.com/bitdump/BLHeli/blob/master/SiLabs/BLHeli%20supported%20SiLabs%20ESCs.pdf)

Other than that the build is pretty straight forward, two 3mm bolts (I used 3x10 flat with washers) to hold it together and space around provided to route the wires. I used normal servo extender leads (tip: cut one in half) but others can be used. The end contactor slot provided 7.6mm x 2.5mm x 2mm
