xintersecty Posted August 15, 2022 Report Share Posted August 15, 2022 I just recently had a experience with prop vibration while climbing out. I continued my climb until 300 feet AGL and then I idled back, turned around, and landed. I called down to Aviation Propellers who did the overhaul 30 hours back in 2019. The plane was not flown much until I took ownership. Grob owners what is the max RPM on the Grob Motor for your prop? Quote Link to comment Share on other sites More sharing options...

If so, would be be so kind as to provide their contact information? Thanks! Quote Link to comment Share on other sites More sharing options...

As for the answer to your question, yes but maybe kinda 🙂 Going over the work order for the prop in 2019. It was taken apart by them and overhauled but they had to send the blades back to Hoffman in Germany for reconditioning. Here is their website: https://avpropellers.com/ Call Us Today! (305) 688-6030|Info@avprops.com Call them and talk Jason about the specifics of the work that should be done. Quote Link to comment Share on other sites More sharing options...
Foley Posted November 19, 2023 Report Share Posted November 19, 2023 My Phoenix stick was vibrating around 3300 rpm - 3500 rpm. Later in the day stick vibrating @ 45-4800 rpm. When we landed later noticed bugs on one blade leading edge and not the other. Any thoughts? Quote Link to comment Share on other sites More sharing options...

Since I got my prop back form inspection, I have been very careful with my RPM management. I had not any issue with bugs throwing the prop out of balance.
