Hi everyone:

I've been encoutering this problem in the past and though it was just me.. but recently this is getting out of hand..

I'm in mid flight doing aerobatics or just flying around and out of the blue the engine dies on me.. after 15-30 flights in the ignition dies without any warning..

Thank fully i haven't had a crash except some minor scracthes [been lucky] but still.

And i've had the ignitions wrapped in heavy density foam to prevent vibration, regular foam. Have placed the ignition in the firewall like it shows and i've seen in many gas planes in the forums and in the field, also have placed the iginiton inside the plane making sure no RF signal interfere's with the other electronics. And i use a 4.8 volt battery just for the ignition, tried a regular switch, heavy duty switch on them as well

I've changed the hall sensor, spark plugs, cleaned the carb rigolously, changed the ressistance that goes in the cap before the spark plug and even bought a carb kit from a lawnmower shop thinking that was it.

It will give me an sputter trying to start but nothing happens.

But if i put a brand new ignition it instantly turns on and it's set for like i set 15-30 flights and again they die.

What's going on?? Not to mention is see that all gas engines using this CM-6 spark plug all ignitions are made by RC Excel?? IS there another brand that sells these iginitions?

Is this a common problem??
