Tom,
I believe that pattern kit pre-dates the wide spread availability of 4-stroke RC engines. It is actually a .90-.120 2-stroke size model but for some reason, gearing a .60 was the thing to do for some brief period of time back in history...
Clearly a tail dragger spinning 18-20" props!
Cheers, David.
Correct. I'm just wondering why the trend subsided.
