A few places to begin, from the aircraft’s story to the people who fly it.

Meet the aircraft

CubCrafters introduced the XCub in 2016. It retains the braced high wing and compact tandem cabin associated with Cub-style aircraft while incorporating a modern airframe and equipment. The conventional-gear XCub is joined by the nosewheel NXCub. The undercarriage distinction is visible before entering the cockpit and changes the aircraft's ground-handling arrangement.

A solo introduction ends on a small grass strip

Hirschman climbed into the XCub over a large tundra tyre and found a cockpit with a particularly good view. The aircraft was still completing its initial flight-test hours, so this introduction had to be solo. Once airborne from Yakima, he enjoyed its energetic climb and crisp responses, with the surrounding landscape adding to the pleasure of learning a new aircraft. A visit to the little grass strip at Buena supplied a different kind of impression.

HOW IT CAME TO BE

History & design

A privately funded project emerges after six years

Hirschman’s 2016 introduction describes six years of internally funded development before the XCub’s public unveiling. Its familiar Cub outline therefore concealed a substantial development programme, rather than simply a new name or cockpit trim.

FROM THE COCKPIT

Pilot accounts

A solo introduction ends on a small grass strip

Dave Hirschman

Hirschman climbed into the XCub over a large tundra tyre and found a cockpit with a particularly good view. The aircraft was still completing its initial flight-test hours, so this introduction had to be solo. Once airborne from Yakima, he enjoyed its energetic climb and crisp responses, with the surrounding landscape adding to the pleasure of learning a new aircraft.

A visit to the little grass strip at Buena supplied a different kind of impression. The large tyres absorbed the uneven ground, making the arrival feel smoother than the surface suggested. The flight gave Hirschman a chance to experience both the new cockpit and the familiar Cub activity of dropping into a small airfield.

A firm touchdown reveals one of the changes

Paul Bertorelli

Bertorelli arrived firmly enough to produce a small bounce, giving him an immediate subject for discussion with Randy Lervold. The landing gear was one of several departures from the traditional Cub arrangement. In the cockpit, he also noticed how the improved view over the nose could briefly make level flight feel like a descent.

The cabin supplied more comfortable discoveries. Leather seats, places to put belongings and provisions for the rear occupant made the aircraft feel suited to spending time in, rather than simply taking around the circuit. His review follows those everyday details alongside the handling: learning a different sight picture, feeling the landing gear at work and appreciating somewhere useful to keep things during a journey.

A delivery journey becomes preparation for teaching the owner

Wes Valpey

Valpey’s assignment began with the aircraft’s initial flight testing in the Columbia River Gorge. The following delivery to Florida turned it into a travelling companion, with stops including Santa Fe and Lake Powell. Airports and water destinations gave him different settings in which to become familiar with the amphibian before introducing its owner to it.

In Florida, Valpey moved to the rear seat for three days of owner training. He enjoyed the aircraft’s responsiveness, while the teaching also revealed the adjustments a newcomer needed to make with the throttle. There were practical irritations too: the water-rudder controls became tiring during long taxiing. His report explicitly leaves grass and other soft-field operation outside the experience he had accumulated.

Compiled factory starter revision 4; documentary sources do not qualify every simulator add-on.

The simulator model and controls

CubCrafters introduced the XCub in 2016. It retains the braced high wing and compact tandem cabin associated with Cub-style aircraft while incorporating a modern airframe and equipment. The conventional-gear XCub is joined by the nosewheel NXCub.

The factory starting point selects CubCrafters XCub across MSFS 2024, MSFS 2020.

How this profile feels

Spring resistance builds with the selected airspeed response. A separate aerodynamic term adds speed-dependent control load.

Valid trim provides the configured pressure relief. Autopilot following is enabled for supported control references.

Controls and trim

The XCub's pushrod ailerons replace cables and pulleys, giving the revised system lighter lateral effort according to CubCrafters. Flight reports describe responsive ailerons and balanced pitch and roll. The tailwheel XCub and nosewheel NXCub have different ground layouts, with straight and amphibious floats available as separate options.

About the values

The gains are normalized profile settings. They describe the chosen effect balance; hand force depends on the device and its output limits. IAS references are tuning values rather than operating limits. Physical acceptance of this revision remains pending.

What the documentation establishes

The cited XCub account describes pushrod control linkages and more precise lateral response than cable-linked predecessors. This is qualitative design context rather than an absolute absence of friction or play.

The cited XCub flight report describes balanced pitch and roll feel with light, responsive ailerons. It does not establish a numerical force ratio.

The hinge and cove redesign gives lower lateral control loads and a natural centering tendency, with only a tiny deadband right on center before effectiveness comes in smoothly and progressively.

Documentary review and sources

These decisions describe the documentary basis and remaining gaps for this revision. Aircraft documentation and a starting setting describe different kinds of evidence.

Spring deadbandStarting value0.035 What it controls and whySets travel around the centre before the baseline spring resists. Smaller values engage it sooner.

GainStarting value0 What it controls and whySets gear aerodynamic buffet; movement and ground-contact cues are separate.
Shaker EnabledStarting valueDisabled What it controls and whyPermits shaker at supported warning conditions; the switch does not establish aircraft equipment.

GainStarting value0.3 What it controls and whySets gear-bump texture during ground motion, separate from touchdown impact.

Limits and open questions
  • Physical force validation is not established for the current revision by documentary review.
  • Generic simulator telemetry and configured control responses require the stated aircraft and device scope.
  • A configuration-specific public source for the float-equipped NXCub force comparison is unavailable. That comparison is excluded from the XCub facts.

Physical validation

No physical force validation is recorded in this public catalogue for this revision. Documentary review and software checks do not establish how a particular device feels.
