Flying in my Sonex N629SX

The weather was really nice today so I continued on my Phase 1 flight testing of my current experimental, a Sonex serial #1629 (N629SX).  Flew for 1:15 a heading north from my home airport MRT (Union County Airport) in Marysville, Ohio towards Lake Erie.  Today I was testing the service ceiling of the aircraft and AeroVee 2180 engine.  Reached 9,050', engine still had life to climb higher, but my mixture needs to be richened up to help keep the CHT's down.  Very busy out here today...notice all of the targets on my iPad/ADS-B!
