Hi Martin thanks again for sharing your project Project my parts of finally arrived and my drop controllerBT is complete. Everything seems to be working fine. I’m considering buying more flashes (Yongnuo YN-560 Mark III) and already have a set of RF-603 II Using one as a trigger and the other to trigger the Flash. but no matter what I try I can’t seem to trigger the flash with them using the drop controller am I missing something?
Thanks in advance Ralph
