FLIGHT CHOPS DISCLAIMER:
I am a "weekend warrior" private pilot, I fly for fun with no intentions of going commercial. I have had my PPL for over 15 years, but still consider each flight a learning experience - I generally take detailed notes after each flight to remind myself what went well or what I could do to improve.... Having GoPro cameras to record flights like this is invaluable. I find these self analysis videos very helpful in my constant quest to improve, and am happy to share. Feedback is invited; however, please keep it positive.

I had a video from Hartzell (or Sensenich) when I was an A&P, I.A. that showed a prop in an overspeed condition. They had a high speed camera make the video, then slowed it down so you could see the ripples in the aluminum blades. That is a real eye opener. It was as scary as the Piper video of a stabilator dancing in a similar way, when the Twin Comanche was over redline. OMG!

It’s really cool to see the balancing process. We got the prop dynamically balanced on the Stinson last summer and it made a huge difference. It wasn’t noticeably smoother but was noticeably quietly and it solved all of the problems we were having from the imbalance (cowling and fairings cracking, loose/missing exhaust studs).

FANTASTIC video, Steve! Apologies for being late - I've been super busy and have missed a ton of your vids. This was amazing! I own an electronic tire balancer, and it doesn't get anywhere near that level of precision - normally within 1/4 oz. is good with wheels. A little less if racing. A prop is spinning MANY times faster, and has very mission critical job to perform, so I can understand the need for that precision! Amazing equipment they have there to balance it right on your aircraft! That is great! Must've made a big difference I'd imagine. Definitely smarter people than I engineering the blades on those things. I can't even imagine how many hours of labor it takes to design one from scratch with the correct pitch and angles, diameter, etc., all playing together. I've been out of the loop for a bit, so I just wanted to mention your RV looks FANTASTIC! CONGRATS on getting her finished! I think I left off at you building the necessary flight time before your first trip - was a while ago! Dan Gryder's vid reminded me to get my butt back over here, lol. Glad to see you're still at it, Steve - top-notch production as usual! 👍

Taking my fourth solo flight tomorrow; still sorting out a few minor issues. I'll be testing the fourth sanding of the nose bowl to eliminate the rubbing. It was very slight after the previous flight but only none is acceptable. Showed up on Van's First Flight list today, which is pretty cool. Next: EAA Sport Aviation, I hope.

I used to build my own drone camera gimbals in the early drone photography days, around 2012-14, before most off-the-shelf equipment was readily available. Balancing those was a pain, but absolutely necessary, and the difference in footage quality between an okay-ish and a really well balanced gimbal was massive. Some things span across industries :)

@@FlightChops So it's been over a decade since I seen it, but if I remember right they weren't able to replicate the myth. No one was willing to let them try it on a real helicopter. So they tried it with a RC one and a scale stamp. It took more than that to see any significant imbalance in the rotor. That said, during research, a mechanic did tell them that he 100% believed it, as mere dust is enough to throw the rotor system out of balance. Whether their results were conclusive or not, I'm not gonna try it.

For the dynamic balancing would the equipment be mainly measuring other engine components that vibrates because the prop had gone through static balancing and it's so precise that it's basically perfectly balanced (a dollar bill will throw it off balance). I mean for dynamic balancing you were basically compensating vibrations from other sources by adding counterweight to the spinner? The precision of Hartzell factory blew my mind. Thank you for the video.
