3D D ifferent motor different 3D plane the Wargo Yak from HobbyKing.
Torque 2814-820 motor, Airboss Elite 45 Amp ESC.

Results

Amps Battery Prop Watts
24 3S 12X6.5 270
37 4S 12X6.5 495
11 3S 11X5.5 200
30 4S 11X5.5 412
27 3S 13X6 287

As you can see the difference between 4S and 3S is huge in real life even thou the 12X6.5 prop puts out more Watts the 11X5.5 is way better at 3D as it lets the motor spool up quicker for 3D throttle response


These are my bench tests

Thanks @Bricks

I ran the 4S test on the NTM2826 1200kV last night. The motor is only rated for 17A so once I saw the first result for the 8x4.5 prop on 4S I decided not to try larger ones. Did a 2S, 3S, 4S series to show the difference in RPM and power.

So this weekend I think I will try to compare flying with the 10x4.7 on 3S and the 8x4.5 on 4S just to see if I can feel the difference that the extra 250-ish grams gives albeit knowing that this is pushing this motor too hard.

Is a Rimfire .32 too big for the Edge 540?
I'd say it would be major overkill. It'll give you about twice the power you need for 3d. A battery to support it would need to be placed aft of the wing to balance it. Not to mention stronger servos and wing/stab structural supports...

When I put my Edge together ( haven`t flown yet ) I did some checking mostly weight versus Watts. What I came up with is either running a 2835 on 4`S or 3540 on 3`S weight wise darn close unless I ran the 3540 on 4`s that a weight penalty. On 3`s the 3540 still put out 35 more watts then the 2835 on 4`s, if I do not mind the weight penalty I can throw a 4`s on the 3540 and gain over 180 watts over the 2835 on 4`s.
