Hi Jongurley,
If 5.00 volts is tested under a load, the battery probably is fine. The load should permit a 600ma current draw.
My experience tells me that DA50 will remove about 180mah from the battery for each 10 minutes flight. Since I am using Nicad, it develops memory. Heat inside the cowl after a flight is another contributing factor to the problem you described. This is specially true in central Texas during summer!

I checked the ignition battery and it showed 5.00 volts,,,could this not be enough voltage????????and it sounded rich in the air, but wouldn't the way it wouldn't start make it sound like the low end was lean,, DICK HANSON WHAT IS YOUR TAKE ON THIS,,,
