Larry,

The first thing may be 'pouring aluminum' for the housing of the worm & wheels gearbox.

It will be something like this,

with the size, ratio and 'V' angle etc. etc. yet to be determined.

A question to the interested and/or the knowledgeable.

A question to the interested and/or the knowledgeable.

Based on the layout in this thread’s post #1, and assuming that;
1 The rotors are hard coupled to the propeller, and​
2 The rotor blades have a fixed pitch setting that is midway between a helicopter hover setting [ref. link below] and a gyrocopter setting.​

Would/could it be possible to temporarily over-speed the powertrain (rotors and propeller) while tipping the craft backward slightly and thereby achieve vertical takeoff?

Thanks,
