IBECs are evil. I tried one and listen to what it did to my ignition:

Well, sooner or later it would happen.

Here is a flying buddy that had one battery serving the ignition and the receiver...

He crashed it...

Dude can wring out a flattie! I've never seen anyone do a rolling loop with a profile before- nice!

That was funny- Wahoo, "Sooner or later...." I thought the IBEC failed and crashed his plane! But NO the battery departed... Not exactly what I was expecting...

Ever since I got into gassers I went straight to the Tech-Aero IBEC on my 50cc Slick and it has been flawless so far Buttface!

I knew a guy once that plugged his ignition in to his SF power expander to eliminate using a separate battery to power ignition. He never had any interference. And honestly I don't know how! Is SF realy THAT GOOD! Thats a true story.
Back in the day I kept every thing as far away as I could from the magneto type engines and ignition boxes of today and I still practice that today,,, even with this 2.4 stuff.

The K.I.S.S. principal prevails every time

A large portinion of the separation requirements were generated during the days and use of magneto ignition systems. The early CDI ignitions offered only marginal improvement. However, over the last 12 years or so both ignitions (reputable ones) and radios have evolved considerably, minimizing many of the early separation concerns. It's funny to read from so many that are up to date and expert with almost every new technological advancement but see them list requirements that were established for products generally no longer in use.

The high tech 3d guys use ancient warbird rules and requirements while complaining about the warbird folks that developed the tenichniques. It really is pretty amusing. One thing remains fairly constant though, even the high tech companies isolate their ignition systems at multiple levels from their primary power systems.

On one of my smaller planes I ran the ignition off of a pig tail on the same receiver battery, did this for weight savings. Never had a problem, range check engine on/off was excellent. All the switches, batteries, and RX were all within inches of each other. I don't recommend everyone doing this, but it worked fine for me.
