With all the interest in tactical VTOL and airmobility, has anyone
seriously considered a Chinook type tandem using Mi-26 rotor/engine
combos (or similar scale western versions) at each end?

Should be able to achieve at least 40,000 kg lift over 350-400km. With
a large cabin, medium armour (bradleys, stryker etc.) could be carried
at upwards of 250knots (less retreating tip problems)

Dynamics, stability and control issues should be a lot easier than
with a tiltrotor setup. All in a package maybe 5-8 years to delivery.

And it would be HUGE. Hard to maneuver, needs a bigger LZ than current
designs,

A good deal less than a fixed-wing aircraft, though.

Ever see an Mi-26? Longer fuselage length than a C-130, and the rotors go
108 feet tip to tip.

But have you ever seen Mi-26 lands? Know how much space it needs to
land? Compare that with the landing run required for a hercules
carrying, say a 15ton payload.
