[NSRCA-discussion] what propeller for an ys 140 sport ?

[BUDDYonRC at aol.com]

Wow Gary
You have a YS-140 Sport running an 18.1x 10.1 that must be a super strong  
Sport
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.
