3W 100 B2 - Is QS mod worth the $$?
One of the 3W failures was due to a pinhole in the CAST crankcase., causing loss of crankcase pressure to the fuel pump in the carb....CNC cases don't have casting flaws.....
DA testing is done at the Tucson Radio Control club field,South and East of Tucson.....
Were you there when they allegedly had problems with the 50 ???
