About 3 weeks ago I organized a group balancing day at Inyokern, CA. I had 4 people signed up however, only 2 showed up. I installed the sensors and started working. The results are indicated below.
First plane
Engine: O320 E2D
Prop: Catto 3-bladed (fixed pitch)
Initial Reading: 2228 rpms/0.48 IPS/ 115 deg phase angle
Number of runs req: 6
Final Reading: 2183 rpms/0.01 IPS/175 deg phase angle
Notes: Aircraft balanced at full power.
Second plane
Engine: IO360 EXP
Prop: Hart 2-bladed (constant speed)
Initial Reading: 2518 rpms/0.37 IPS/ 344 deg phase angle
Number of runs req: 7
Final Reading: 2510 rpms/0.01 IPS/024 deg phase angle
Notes: Owner selected 2500 rpms for balancing runs. Previous balancing (by me) was done at 2650 rpms.
It was a great day. I got to hang out with some RV guys, ate some good burgers, they checked out my project but most importantly they went home with a very close to perfect balancing job. Still shooting for that 0.00 reading that someone else on the board was able to obtain. Maybe the guys can give you guys a PIREP later. Pics below.
