We have a similar setup where the electrics designated area is on the left hand, behind the runway going perpendicular to it. The electric pilots don't seem to make a point of being mindful that one end of their runway butts up against the end of the gas runway and that end it typically the approach for the gas planes.

The pilot boxes are also right there on that end of the runway (another set at the other end of course but because of our wind direction we rarely stand on that side) so then they disregard those facts it is just like having a swarm of large flies around your head while you're trying to fly your own plane. While it might not damage me much to be hit by one of these electrics the chain reaction that could be caused is cause enough to follow the rules. If I loose sight of my aircraft because I was distracted by another plane (be it electric or gas) then that person who caused the distraction (accidental or not) will share some if not most of the blame for whatever my aircraft does once I am no longer controlling it.

At least that's how I see it.
