Dear AllWe are introducing Ellipso, a new domestic robot drone from FRACH robotics and we would like to hear your feedback!Ellipso is an autonomous intelligent home robot drone, which is always online, listening to you and ready to execute your…
My concern with using the larger props for cruise flight is to generate more lift than the drag for a given required speed. It is OK for e.g. 3D flyer to have prop thrust e.g. 200% of the weight of the plane, but it is an overkill for a…"
"Hmm, APC E 12x6 prop is really a wrong match for Talon and 60km/h cruise speed.
These are the data for APC E 12x12:
240g static thrust
20w prop power; 28w total electric power
51km/h pitch prop speed; 60km/h cruise plane speed
"Actually just running the numbers again with the http://adamone.rchomepage.com/calc_thrust.htm and APC E 12x6 prop and I get:
853g static thrust
92.4W of required prop power
about 130W of required total electric power (20% ESC losses; 20% motor…"
The cruise speed is given as the business requirement; in this case at least 60km/h. It makes sense for 100km flight with the flight time of 1h40min. Also the wing aspect ratio and wing loading are constraint with the given model: Talon…"
1/ I have used this RC prop calculator (http://adamone.rchomepage.com/calc_thrust.htm) to find out required prop power for 12x6 prop with straight cruise of 60km/h. And added 20% ESC losses and 20% motor losses. It roughly matches my…"
