Just wanted to thank BT4 developers for finally bringing full support to my wireless adapter(no installs/patches to add) in the new R2 release. Fully working monitor mode and injection! The card didn't work properly under earlier versions of BT4, and it needed a lot of patching and editing in BT3, now works like a charm!
Edit: Added demos:
