World Models CAP232 Castrol
Hi, I just bought the CAP232-46R from World Models (Castrol). I really wanted that plane because it has very nice decals.
56.5"wing,496sqin, flying weight 5.5lbs(2500gr) and recommended glow engine .46 or .70 four stroke.
I already weighed the plane completly empty: 1450gr (3.2lbs)
Because the noise restrictions are going up every year in our country I was planning to make this my first electric powered plane.
But I could use some help to determine the correct power plant for that plane.
I already found different ways of calculating the motor. Some people start with the weight and then calculate the Watts needed (150W/lbs) and some people start with what prop you need and then look into the motor specs table.
I was planning to use a Cyclone60 (http://www.cyclonbrushless.com/), probably not available in the us but it has the following specs: 12-20cells, 600rev/V, 90%eff,35A/45Apeak, weight235gr.,660Wcont with 20cells
If I use a 5S pack I can produce between 555 and 832Watts with this setup.
Would this be a good configuration? If I plan an AXI motor which one should I use then? Type2826 or 4120? I noticed that AXI has less efficiency and the motors are also heavier.
Thanks for your help!
