Default electric props

hey guys, i want know if anyone makes a 12x14 electric prop? i am using a 14x13 carbon fiber prop and my axi 413016 cant really push it at 8s. i was thinking of going 12x14 electric prop and see if i can run it at 10s. thanks.

I strongly recommend not using an electric prop with that motor. I broke a 12x8E with 9S, it just folded. That motor runs almost 2HP (1500 watts) full out. Even though the peak torque is less than from a .60 glow the average torque is higher.

right now i am running 8s with 3200mah each on that axi 4130-16 on a sundowner 50 and with the battery fully charged i can not pull full throttle until the battery is lower in voltage, the motor make this grinding horrible noise, i am running a 14x13 grauper carbon fiber prop. all timing and setting are as low as possible on my hv110 esc. the plane is fast but i think that prop is to big for the motor. i am thinking of running a smaller prop and more volts to make it the rpms compensate for the less pitch i will be using. what do you guys suggest?

A 13x6 Master Airscrew S-2, HV-45 and 9S 2100mAh is what I'm flying is a 65" WS trainer, works great, 24 Amps static, averages 8 Amps in the air.

APC do have 12x14, but not an E-version of it.
So you run a 14x13 on 8S [X(] I think 14x10 is max...

well i am running a 14x13 right now but i have to wait for the voltage to drop just a little in order pull full throttle without any problems. the motor is overloaded in amps pulling 80amps at full load. i need to step it up to a smaller lighter prop.

Overloading? No, you are far above overloading Max 60A bursts, should be max 40A to keep the efficiency at a reasonable level. Strange you haven`t burned the motor already! Take care, could be expensive flights if you don`t reduce propeller size before next flight.
