Powersport RV-6A flew into Airventure on Wednesday morning and stayed through Sunday.  We parked in "Auto-Conversion Row" this year where people could easily see our plane alongside several other auto conversions and make comparisons.  We also chose not to have a booth this year, instead staying around the plane and talking with lots of very interested flyers.  We gave a forum on Thursday evening that was very well attended.  After Ray Richardson covered the history of the Powersport program, Steve Weinzierl presented some of the engineering principles used to design our reduction drive.  Keith Holm covered information on our Engine Management System.  Leon Johnson demonstrated our multifunction display and engine data display and collection software, and Chris Armstrong showed some of the engine to airframe integration work that we are doing for the RV-6A, RV-8, and Lancair 235.
