April 5th, 2008: Propeller balancing

Flight Hours: .6 ground time

Total Hours: 4.0

I found out during the week that Bud Stordahl from the FlySoob list has his plane hangared less than 100 yards from me. Boy did I feel like I had spent too much time in my hangar and not enough getting out to visit my neighbors. Bud is running a stock ECU, EJ-22, in his Protec. It's a great looking plane and I can't wait to get a look under the cowl.

Anyway, Bud and some friends were at the airport when Mike McGee and David Woboril showed up with the balance equipment. David is another member of EAA 105 and has an EJ-25 in his RV-9A. So, we had a great crowd for the event.

Mike operated the equipment while Bud and David provided great support help and I ran the engine. I was really happy to have the help. It continued to rain and we had to push the plane in the hangar between runs and back out to test again. The procedure took about 2 hrs to complete from the time Mike and David pulled in. The numbers went like this:

PROPELLER BALANCE:
Original .472 ips @ 48.6 deg
Weights added 8.9g @ 30 deg 14g @ 90 deg
Final .058 ips @ 249 deg
