I don't think so, I'm sure I heard "romeo mike". So it would be G-RVRM.
This website is reporting it as RF
ASN Aircraft accident 29-JUL-2011 Piper PA-38-112 Tomahawk G-RVRF
Pity if it was RM as I always found that the nicest one of the fleet to fly, not that that matters a jot compared to the tragedy affecting the crew and those close to them.
