A mod rocket called XRR-1S X-Wing Rotary Rocket Prototype. Built with 211 of the finest parts, its root part is fuelTank4-2. Please note it requires B9 Procedural Wings mod, in addition to those listed by KerbalX.

Built in the VAB in KSP version 0.90.0.

Pilots Beware! Unproven craft! Do not fly without life insurance!

Inspired by the Rotary Rocket Company of Mojave, the X-Wing Rotary Rocket utilizes variable pitch, jet powered rotors to take off vertically and can transition to horizontal flight like the Focke-Wulf Triebflugel tail-sitter interceptor. Depending on your test flight regimen, the XRR-1S can function as an experimental aircraft or a rocket ship that uses rotors for supplementary lift.

The ship’s full flight envelope is yet to be explored. As test pilot your mission is to obtain familiarity with rotary rocket operations and devise a test regimen to expand the frontier of rotary-winged rocket flight.

First, send the craft up high into the upper atmosphere and use rotor pitch controls ( : and ‘ are collective / rotor pitch controls) to allow the rotors to auto-rotate. In this manner, the drag from your rotor system allows you to decelerate to a safe landing.

Second, experiment with rotor pitch control to master the use of rotor lift to assist vertical flight, or transition to horizontal flight and attain supersonic speed with the rocket engines at stratospheric altitudes.

Lastly, see if the thing holds up to sub-orbital flight and attempt to develop an SSTO version!

The majority of these tasks should be relatively painless, as the creator of the craft had tested the vehicle up to supersonic speeds. As landing can be tricky, no less than eight airbrakes are installed, plus two parachutes to help you fall like a brick, at least until the windmilling rotors take over!

Be warned that even in real life, the aerodynamic behavior of rotors at supersonic or hypersonic speeds are unknown. The real-world Roton Rotary Rocket did not use rotors on ascent for this reason.
