yeah it looks like it will move like the Rarebear.
Being Conservative, I have balanced a 4.75 x4.75 prop and Replaced the 4.1x4.1 Don't Think it Should make Too much of a amp Difference will do some Tests Tomorrow.
I think Hobbyking are being cautious with there prop size as to not overheat esc and motor.
I know from my scorpion Sky funs running a 3595kv motor on 4s as well as using scorpion Calc at 3500kv should be approx below will confirm once bench tested, two sets of fiqures one full burst which is a Extreme measure and the other is Nominal Running Current Voltage at Full Throttle.
APC 4.1x4.1......................46 AMPS/14.8 volts.......................57 AMPS/16.8 Volts
APC 4.75X4.75..................60 AMPS/14.8 volts......................73 AMPS/16.8 Volts
APC 5X5..........................69 AMPS/14.8 volts......................82 AMPS/16.8 Volts
BENCH TEST RESULTS WITH 4s Lipo Apc 4.75 X 4.75 = 58.76 AMPS, 13.68 Vm, 813.60 Watts
................................................................... Apc 5.0 x5.0 = 72 Amps, 955 watts

What Do You Mean Theres a Throttle Curve ?, Its Either all the way up or all the way down
