Q: I am about to change my Alfa Romeo boxer engine to a Lycoming O-360A1F1 on my experimental Glastar aircraft. I read your answer recently to a question if LASAR is really useful (Will my engine benefit from new technology? Jan. 12 issue). Its actual price is $2,500. Do you think that it is really worth this high sum?
My mechanic has doubts, saying he is not confident in electronics — that if the electronics don’t work, the engine will stop. He also says that standard magnetos usually always work.

A: I appreciate the fact that you read my article on the LASAR system. One thing I overlooked when explaining the system is that any interruption of the three data sensors — manifold pressure, cylinder head temperature, or rpm — and the system automatically reverts to the fixed timing on the engine just like the LASAR system was not there. Therefore, the engine would not stop as a result of the LASAR system experiencing an electronic failure.
