Here is a test for the unconvinced that anyone can do:
I removed the spark plug and propeller from the Lazy Ace that I just rebuilt. It has an NGH26cc and RXCL ignition.
I then chucked the motor shaft in a hand drill.
I turned on the system and the ignition and put the spark plug in its cap and ran the hand drill.
I pulled the sparking plug back as close as I could to the RX antenna.
The system operated normally.
How long shall I run it Dan?.
BTW that is a nice clean installation in your picture. My only comment is "Look at all of that wasted space"
