Servo for vintage car

[super__dan]

I need a servo for my vintage car on the cheap. In true period style I was thinking of getting an old Futabe 148 or the old equivilent acoms and hot wiring it like we used to do back in the day.

Now I'm 100% happy doing this to a 148 or acoms because I know it used to work, but can you do it to anything else? I once did it to a Hitec and it went up in smoke.

Does anyone have an old 148 I could swap for a packet of crisps (your choice of flavour) ?
