Flying around the neighborhood today and about 30 minutes into flight

there was a momentary hic-up. Everything on monitor looked normal, so

richened a tad and continued flying. About 5 minutes later, same thing

second verse, and then a third time. Went to full power and rich and it

did not repeat. No miss while descending to land or while taxing in. Ran

up a full static for a minute on the ground and everything appeared

normal.

 

Any suggestions???

 

Hum-m-m. 

Did hiccup seem like total power loss, or possibly just one rotor?

Check all electrical connections associated with ignition and fuel injection.

Check for possibility of small amounts of water though fuel system.

Anything about conditions at the time that might suggest intermittent vapor bubbles into pump. Check data-logger for blips in fuel pressure (oops; there’s that ‘no data-logger’ issue again).
