There is not really enough information in your post to analyse your 10%
extra time. However if you kept the same rubber length when you increased
width then you have increased the available energy in the rubber by about
30% so the 10% increase in time is not a surprise. Also the torque absorbed
by the propeller varies as the fifth power of the diameter so the large
increase in diameter of your new propeller means that the rotational speed
will be much lower so you are not ‘running out of turns’.
Did you increase the P/D ratio in an attempt to match the increased flying
speed dur to the extra weight of rubber?
