Hi Brian, This e-mail just showed up------------Revmaster sent me Autolite 425 plugs which are resistor plugs according to their web site. Revmaster does use a shielded harness. After telling Joe at revmaster about the radio noise he said what did u gap the plugs at? I said since there were no instructions I left them at .030 as that's what they were all set at, then he said that's my problem, re gap to .016, so I did and believe it or not the noise went away on the ground but in flight it came back about 75% of what it was. So I called an avionics shop and was told to get some shielding ( the tubular variety that is woven like Chinese finger cuff's ) and slide it over the last couple of inches of wire prior to the plug boot and down over the boot as well, and for good measure solder a wire to the shielding and ground that to the block as well. So I'm waiting for the shielding now. I may call Steve at Great Plains, I completely forgot about him----------------------------Thanks!
