As you know, Ive been using the RCExcl ignition for glow plug thread and 1/4-32 spark plugs.




These are not the best options for reliability as the silicone plug boot keeps sliding out and results in an arc between the boot and the spark plug head. - HUGE RFI!

to overcome this, Ive put a couple of layers of heat shrink on the boot then used a thin wire to crimp the boot in place (without damaging the silicone underneath)

It works for now.. But Im thinking about modifying the 160FX head, to accept standart 10mm CM-6 plugs.



But before doing this, I wanted some feedback. Would the head have enough material, do i need to make other mods other than enlarging the hole to 9mm and tapping with M10 tap?

Would it likely fail in flight? any ideas?

BCCHI - could you post some photos of the ST head?
