<DIV>Wow Gary</DIV>
<DIV>You have a YS-140 Sport running an 18.1x 10.1 that must be a super strong
Sport</DIV>
<DIV>I have been running an APC 16 x 11 on my YS-140 Sport with #2 Magnum fuel
for the last couple of years with good results RPM between 8400 &8800 plenty
of power, airplane is a 10-3/4 pound Impact I sometimes run the APC-17x10N
but RPM drops to about 8200 The YS engines like to turn and the 17x10 will load
the engine to much sometimes if the conditions and settings are not
perfect.</DIV>
