Mselig,
Thats another thing we need is more electric motor selection. I mean I had no Idea I could use a 2000+ watt motor to power a 40" plane.
I can guarantee the little scaled down "mini funtana" has about a 3:1 Ratio in it. something not possible in real life at that given weight with that airframe.
That's right. In the sim you can pick any motor, and then when the Scaling Wizard is used, the prop size can be put in and also the approx max speed of the prop. The scaling is then done inside the sim to resize the prop, figure out the drag, resize the motor, figure out the friction/losses, and then it adds the right amount of power (re-scales the motor) so that the scaled prop spins at the speed you set. All of this is used to scale a plane up or down (e.g. like the Ultimate mentioned above - going up to 256 inch span w/ a variable pitch prop and down to 40 inch span w/ an electric motor).
I tend to agree. The "mini funtana" is a bit hot (but fun I think!). Maybe it could only realistically fly for a few minutes like that??? It's easy enough to tweak. Make a copy, and then set the max prop speed slower.
It might be handy to have the sim report thrust-to-weight ratio when flying?
