I recall a B-bar that attached to your base-tube that could be adjusted in (nearly 360 degrees as I recall) in flight. I’m looking to build one. Anybody have an old photo. I can’t remember the locking and rotating mechanism/hardware.
The ones I'm building are similar. Instead they slide over the base tube and have a bicycle seat clamp on one end to hold in place (360 degrees movement). I opted for two flat "D" shaped bar extender handles. Much like yours but I want to be able to adjust in flight with no tools.
