Can anyone clue me in to a guide on rotor sizes and minimum/maximum RPMs needed?
35cc gas engine (3000 - 7000 RPM) --- 4-way speed increasing gearbox --- 4 x right angle speed increasing gearboxes (2 x CW& 2 x CCW) --- variable pitch props.
Weight 25 - 30 lbs
Props ~ 24 inches
I'm waiting for the tech supports at the gearbox companies to give guidance on high RPM bevel gearboxes.
What type of blades would fare best for this application?
What RPM levels would I need to maintain hover and flight with 24 inch props and 25 lbs?
Naysayers - Redundant failsafes, backups and safety features will be paramount in this design in the long run.
