Hi,

I have a outrunner motor 3500KV, 3.17 mm

I want experience a prop. i heard good size is 6 X 4

So what do i need , prop, prop adapter , prop saver

Pls guide.

It would be great that you know/post other specs of the motor to determine the Size (cell count / max amp/thrust etc) only then the correct prop could be decided.

From my reading, 6x4 would be a little mover kill for 3500kv motor. Keep it 6x3 if your motor can take 8+ Amps. (90W) or 5x3 if below 80watt.

Finally, you  would need the Motor, ESC, Receiver, Lipo, the prop, and prop adapter/Prop saver + Band if you motor does not have an integrated adapter like few motors have. The choice between the collet type adapter and prop saver would be purely on what kind of prop you want to put. For flexi GWS type props, prop savers are better. For hard sports props like those from EMP/Master Airscrew, use prop adapter, though its not a thumb rule.

hi,

below are the motor credentials, ESC is 30A

- Speed Constant: 3200KV
- Motor diameter: 27mm
- Shaft diameter: 3.0mm
- Motor length: 30mm
- Motor weight: 48Grams
- Free load current: 17A
- Working Voltage: 11.1v
- Max efficiency: 85%
- Max current :17A
- Speed controller requiement:30A

Now you are talking... thats nice info... Start with 6x6 and see motor/ESC remains cool at 80%/full throttle, only then move to 6x4. RC Dhamaka has both 6x4 and 6x3 props I guess and also the Prop Adapter (3mm shaft are most common).

I have seen 6x4 more with 2200kv and lower speed motor..

At 3200 KV    6 " will cook this motor  your most likely size is  around 5 "  Start with a 4.5 or 4.75  and then up it  if you feel confortable with it
My advice don't even attempt it with a 6" the max amp and the full load current is 17 A .
I am assuming you are using  a 11.1V battery.
