Hi H, i'm not sure which one is the soft touch switch. mine has an orange switch box thingy. it's been pretty reliable for me since i got it. i'm hoping that being tight in the box will keep it safe. but i am concerned with it. i'm waiting to finish the build before i decide where to glue the switch to.

i would run without a regulator but i'm not sure if the low profile koprop servo and the sanwa erg VZ can handle .4 to 7.6 volts. it would be great if i could just use a plug straight from battery to reciever
