Motocalc for brushless setup wanted please
Hi can anyone please help me out, i have an older sensored brushless motor (Aveox 1114/4y) which i hope to run on a Zagi and i need the motocalc figures for amps etc. Here are the motor specs and it will be running of seven cells 1700 scr turning either a 5x5 or 4.75x4.75 prop, any help greatly appreciated,,,,,,,,,Neal
The Aveox 1114/4Y motor has been discontinued. However, here are the motor constants for those of you with them, or if you wish to compare them to the new motors.
Specifications:
Kv 2743 rpm/volt
Io 1.5 A
Rm .040 ohms
6-14 cells
40A
Dimensions;
1.096 Diameter,
2.5" long without shaft,
5 oz.
4-40 screws on .8" centers
1/8" shaft

Doesn't look promising.. With 7 cells and that small prop you are not getting much efficiency out of that motor and only 11 oz of thrust (same as speed-400)

A 6x4 looks better to me

thanks Boomzilla
Cheers for taking time to do the calculations for me Boomzilla, i guess i will try the 6x4 , i was just worried that the amps might exceed the 35amp (60amp peak 10secs) of my Ez30 esc. But i see with the 6x4 its coming in at under 25....cheers
