Use of Arduino to control a Spike Relay

[docdavies]

Ok, I'm almost crazy enough to laugh and cry at the same time. In the following reference:

http://www.vexrobotics.com/217-0220.html

They say, "It (the spike relay) can not be connected to an R/C hobby type receiver".

Then lower in the specs they say, ---- "Control Signal:Hi: 3V min @ 4mA; Lo: open or ground."

Surely we have one electronics expert in the forums that can wade through this mass of info and render an expert opinion??
