If you read my original posts, even though I figured a way to do things, I still would like to know what other people do, what solutions have worked, not worked, etc.
For smaller models a "12" rule" is difficult to adhere to. In my application, 2 meter size pattern models, it simply can't be done simply and efficiently. You didn't say whether you use a CDI type ignition or magneto type. CDIs have better shielding and RCEXL and CH CDIs are better in that regard than others.
As a couple others mentioned, try using the Tech Aero IBEC between your CDI and RX. I assisted in testing the prototypes and can state with certainty that they indeed are excellent units. All of my gas planes have one. Several important benefits. I use the unit in both 72Meg and 2.4 gig systems, not a single issue 3 years running and some 900 runs later
