As far as the wire hazard goes...

If you dont have the sense to make sure the things are clear, then yes, it can be a danger. I like how you recommend the wired glow driver though....kinda contradictory to your "danger" speech, a wireless one would be better..

In my opinion, a wired starter and wireless glow driver. It can be tricky to keep both wires out of the way if you use a wired starter and glow driver to the panel, but even then (like when i forget to charge the glow driver) its not bad, i simply keep the box behind the prop line...and put my knee on the starter wire to hold it in front of the prop..

You are correct though, in that it is safer to have everything wireless...but its also more expensive, and the alternative isnt really much more dangerous if any at all as long as the individual practices common sense...

My backup for the banana-clip to aligator clip is easy...i have some gator clips laying around...if i need to use my banana clips on a battery directly, i use the gator clips to "hold" the banana clip against the terminals...simple enough for me as i rarely need to do that (once in a year of flying so far)
