I pulled the cowl off again tonight to see if I missed anything and found something I thought was interesting.

the shielded cables from the spark plug covers run underneath the aluminum standoffs for the engine mounts. they don't touch the standoffs but there is enough slack in the cable going to the ignition box that they could feasibly run against them.

I slit some tygon tubing and placed it over the part of the cable that could touch the standoff, then wrapped it in electrical tape and bound it with zip ties.

is it possible that any rubbing from the ignition cables against the engine standoffs could cause RF while in flight?

thanks again
