Peter R-B, yes, just a bit! The 47J2 was a strong beast. That picture was the result of stretching a low level (250ft AGL approx) auto rather too far to more level ground in the hills of the Welsh border when the freewheel unit disintegrated. Ran out of RRPM a bit too early but preferable to rolling down the steep hill which was underneath us...sometimes it just ain't your day!
