We built 2 BRDs with version 5 of the blade before the break to be used as witnesses for the drift over the next weeks. BRD 8 v5 is made with a baked blade from last summer. We didn't have time to properly tune the BRDs, but they can still be used as witnesses.
Here are the measurment results for BRD 7 v5 before and after the break. We see a negative drift for both modes. For the roll mode the drift is -0.1% and the bounce mode is -0.3%.
