Last week I had a emergency landing because my engine (Saito FG-60R3) was hesitating every couple of seconds.
I could clearly hear no ignition and not related to the engine.
Luckily I fly Jeti and have recorded the telemetry. I found the Voltage AND Current dropped to 0 V and 0 A now and then.
This must be problem from ignition battery up to SparkSwitch Pro as there is the telemetry coming from.
I checked battery and connectors but al seems fine. So it has to be the SparkSwitch PRO that gives the problem.
I run the engine on ground and could not replicate the problem .
Does anyone has an idea?
