hi all is there any site that i can use to play with prop size to get the best out of my setup.
dose not have my motor.my setup is
hyperyion HP-Z 3025-12
hyperion 80a esc
aeronut 15x10 folder
2x2500 25-50c genace
curently i am pulling 91amp with 1080 watts.
so i like to know if there is a site i can play with prop to see the best results,,,
thanks for all your help.

You can use my Drive Calculator. But it works only with the Microsoft IE.
The HP-Z 3025-12 is not rated for 91 A.
Peak current is 38A 60sec, 42A 10sec.
Resistance Ohm: 0.036
Io A: 1.79
KV rpm/V: 665

Here's some real-world test data for your motor: Bungymania Motors Data Base: Hyperion z3025-10
For working out what's best I use Motocalc, because it calculates the performance of the whole system (not just the motor). It costs $39, but is free to download and try out for 30 days. Here's a sample output:-
Motor: Hyperion HP-Z3025-10 (bungymania); 933rpm/V; 3A no-load; 0.05 Ohms.
Battery: Hyperion G3 CX 2500 (25C); 3 series x 2 parallel cells; 2300mAh @ 4.02V; 0.0021 Ohms/cell.
Speed Control: Hyperion Titan 80 BEC; 0.0012 Ohms; High rate.
Drive System: Aeronaut Folding 15x10; 15x10 (Pconst=1.11; Tconst=1) direct drive.
Airframe: Spyder 2.5m; 714sq.in; 70.1oz RTF; 14.1oz/sq.ft; Cd=0.036; Cl=0.42; Clopt=0.67; Clmax=1.04.
Stats: 242 W/lb in; 143 W/lb out; 19mph stall; 24mph opt @ 31% (92:00); 30mph level @ 38% (63:56); 2840ft/min @ 90°; -143ft/min @ -3.9°.
Conditions: Sea Level, 101.3kPa, 20°C
AirSpd (mph) = 0.0
Batt Amps = 90.8
Motor Amps = 90.8
Motor Volts = 11.7
Input (W) = 1059.3
Loss (W) = 433.7
MGbOut (W) = 625.6
MotGb Ef(%) = 59.1
Prop RPM = 6647
Thrust (oz) = 116.6
PSpd (mph) = 62.9
Prop Ef(%) = 0.000
Time (m:s) = 3:02

thanks so much.it looks like it may be the sweet spot for that motor BTW" it is the 10T motor not 12,,,,it tells me the climb out rate will be very good and using 8 to sec motor run with motor on switch will be just fine.
