Versions: V1 and V2
- To turn the electric 41-inch span Brio into a scaled-up 74-inch span, Saito-180 powered Brio with a 17×6 prop, the first step is to make a copy of the original Brio. Then edit that and pick the Saito 180 glow motor together with the APC 17×6 prop. Then in the Scaling Wizard (size), set the span to 74 inch. In the Scaling Wizard (propulsion), set set the prop diameter to 17 inches and the max motor speed to 9500 RPM (a reasonable value for this motor/prop combination). That’s it. Click OK to finish. That’s all you need to do to make the transformation.
- The last two steps mentioned above (prop diameter and RPM) are obviously simple (like this example, click here), but it does require some understanding of how things work. When picking the Saito 180 motor and 17×6 prop, that swaps out the electric setup with the Saito glow setup. So it’s like putting a monster engine on the original 41-inch span Brio. That by itself will not workout well. Once you go into the Scaling Wizard part, the span is set to 74 inches. Stopping things there would take the Brio and Saito motor and scale everything up to 180% of the original. The Saito would scale up and that would produce too much power. To avoid that, the motor RPM is set to what the original Saito 180 can produce (say, 9500 RPM), and the propeller is set to 17 inches. This way the motor and propeller are not scaled up but are over-ridden by the specified RPM and propeller diameter.
- Another tidbit, the motor sounds can be changed to the Saito motor. This is done by picking that motor sound (see images below). The RPM range shown in the image only means that correct sounds can be produced over that range — not that the motor can produce that kind of max RPM(!). To get air rush sounds (for the larger plane), pick the air rush sounds by clicking on the Sound button a second time, and pick the air rush sounds for the Ultimate TOC (see graphic below). Now you will hear the swoosh of the plane when the motor is killed.
