No need, I got three sets of instructions, besides I can't measure to .5mm without a micrometer. I find that it is much easier to describe the method than to actually perform the measuring. I also find it odd that they simply didn't provide the timing in degrees and was even more frustrated when I tried to get the timing from RCS. I gave up, set it as close as I could, measured the timing and found out it was set at 6 degrees BTDC, that made sense so thats where it gets set when necessary.

The measurements you posted are the alternate method, did you try the first recommended method described in the instructions?

My Rcexl ignition arrived today, will be installed tonight.

Does the size of the battery matter? Zenoah recommends a 1500 mAh battery for it's G20 ignition. I've been running my RCexl ignition with 600 to 700 mAh packs.

That's because the Zenoah ignitions are power hungry. They use waaaayyyyy too much juice.

If the ZDZ FAlkon ignition are anything like Vlach (they once were partners), then the ignition failure mode can be "no advance". This is the mode that the ignition uses when battery voltage gets low. The engine runs with both cylinders, but without advance and so limits the rpm. This way the pilot is warned that he should land as quick as possible.
Sometimes the ignition fails by reverting to this mode even when voltage is high enough.
Just to be sure: check your wiring, battery and switch under load and vibration.
