Gemfan Plastic Props vs Graupner E-Props Comparison on TBS Discovery Quadcopter
This has been long overdue, but I finally got my E-Props last week and just got around to doing some testing. The video shows some sample footage from the GoPro for each prop as well as the vibration data with the iSeismometer app for iPhone. The Graupner E-props fared much better than the Gemfans, but as I point out in the video my vibration woes are not completely gone. Next up is to do some motor balancing.
I found that Graupner E-props are pretty difficult to come by here in the states, but did end up ordering from Amazon.com:
If you want to see the vibration data in the Google Spreadsheet then go here:
The vibration material I'm using is called Kyosho Zeal. It's super double-sticky and as you see in the video holds my iPhone on the quad without the need for any zip ties or rubber bands.
The E-props are about 10X more expensive than the Gemfans, but I believe they're worth it. I'll continue to post more info about these props as I spend more time in the air with them.
