Had the same, but it was from the left bottom. A bit of speed tape, and all is fine.
bunch of spanners vibrating around in the rear bagage compartment
the classic skirt buzz?
------------------------------------------------------------Hi I get a bad rattle in the rear above 155kt, sounds like a bunch of spanners vibrating around in the rear bagage compartment but the plane is not vibrating, it got to be something In the exterior, anyone else having something similar?

It is probably the canopy fairing to fuselage. I've seen this on several RV-8s including mine.
Install a felt tape pad glued to the canopy skirt a half inch or so from the edge.
That will stop the buzz rattling and calm your nerves!
Skirt-buzz fixed! A strip of felt taped inside the rear part of the skirt did the trick, I dived up to Vne without any buzz, many thanks for the tip!
good news....its amazing how these "loose" things can buzz and vibrate. Got a call few days ago from a flight attendant on the airbus 320 saying they heard a loud humming and felt vibration around 12 DEF area. I wrote it up and the engineers found a 6 inch strip of wing root fairing rubber detached....at mach .78 they wiggle around a bit! good things to look for on the walk around.
