Tiger Shark Engine's (ANYONE HAVE ONE )?
10 or 15 years ago I bought the 40 size, flew it on 4 or 5 planes ,then loaned it to our club to use on the club trainer,we use 15% Sig fuel and OS#8 glow plug,it still has lots of power,and drinks very little fuel,I should buy another Tiger Shark,because this one has been one of the best engines I,ve ever used.
Have a goodun,John.
