Some Observations from Roger Moss regarding His Scott

Roger Moss of Moss Engineering, builder of the Scott raced by Paul Dobbs in 2004 and 2005 had this to say about our magnetos.
 
The mag on a Scott runs at engine speed, so must function efficiently up to the equivalent of 12,000 rpm on a four stroke.
Despite the very best attention to traditional BTH mags, they would not maintain timing accuracy into these higher revs and operational life was short.  I designed and built my own electronic magneto using PVL components, but these obliged me to run at twice engine speed.  Although this system was reliable, some loss of timing accuracy was sacrificed.  I was pleased to obtain one of Tony's first BT-H mags for trials on my Scott.  This magneto has proved 100% reliable, accurate and effective.  I recommend without any reservation.  Without this mag, Paul Dobbs could not have demonstrated the true potential of a good Scott in so dramatic a fashion as he did in 2005.
