Very hazy day. Severe weather developed late in the day yesterday, drenching areas around Indianapolis and dropping nickel size hail. We were spared. This morning the clouds were gone, but the heat, humidity and air pollution have combined to create thick haze.
FOX will be televising the take-off tomorrow morning, live, on the local affiliate's morning show. It means lifting off 45 minutes later than I'd planned, but the publicity is worth it. The flight to Dayton (MGY) is about 110 miles, and if the weather Gurus are correct, when the breeze starts it should be from the SSW. Since my course is about 100 degrees, I may have a bit of help, but that will be canceled out by the crabbing component. I'm hoping the flight will last about 4 hours.
I'm very pleased that almost everyone I'm speaking with now acknowledges the advantages of the HKS engine over the Rotax 582. (And that means I've been speaking with a lot of envious Rotax users!) If you need a 912 for the power, then granted, the HKS won't do the job. But if a 582 will suffice, the HKS is a better choice.
Why? Let me list a few reasons:
Performance-wise, having flown a Destiny with a 582 for 3 years, I can't discern any real difference. The HKS has a 3.27 reduction, and swings a 72 inch prop. Although I've not measured the thrust, I can't ignore the fact that on this trip I've lifted off, fully topped with 18 gallons of fuel, from airstrips that were over 7,000 msl, and (at 6 in the morning) already had density altitudes of over 9,000 feet. The highest density altitude in which the HKS pushed me along was about 13,500. It's hard to knock that kind of performance.
I'm sure there are those who will have a different opinion on the subject than I, but those are my thoughts.
