Interior Detail & Futures

Personalized to your taste.

We understand an aircraft cockpit is a very personal part of any aircraft. This is why we don't have standard cockpit layouts.

Every Whisper X350 cockpit layout is custom made to the client’s needs, insuring great comfort and ergonomic use.

More coming soon.

"The X350 Gen II is one of those aircraft that makes you grin every time you take to the sky.

To say the performance is spectacular would be an understatement indeed!

It's one of those unique and rare aircraft that does everything well "

The X350 Gen II offers increased performance and headroom, a full leather interior, dual L&R Controls, two-tone exterior paint scheme, optional 2-Axis Autopilot and a more spacious instrument panel to accommodate 10.4 inch EFIS screens to name a few.


The New Whisper X350 Gen II is an "almost-ready-to-fly", quick build kit.

The X350 Gen II kit is 49% built and allows the owner to complete the remainder of the build process themselves.


49% Completed means all structural and fuselage parts are completed, including all paint spray work and most of the exterior work.


The 51% of the remaining work and finishings includes all electronics, engine fitments and interior work to be done by the owner. No prior knowledge of composites is required or necessary.

The X350 Gen II is the pilot’s plane. It expresses the pilot’s bold statement and style. The exterior paint style and color scheme will be your most important stylistic decision.


It will also be the reason for envy both inside and out of the hangar.


Choose from a variety of styles, then choose your base and accent paint options.


* Final performance may vary slightly




All parts required to finish the Whisper are included within the kit. This includes a full leather interior custom built for the pilot. The estimated time from construction to finishing the 51% by the owner will take an average of 600 man hours to complete, depending on your skills or assistance from friends or others.**


A well-detailed construction manual (featuring ample illustrative photographs) is provided with the kit. Quick assistance can also be given by phone or via SKYPE call. Whisper Aircraft have a growing builders forum too, where owners can share their construction experience and knowledge.*


*All current build forum aircraft are 1st Generation Whisper Aircraft. 1st Gen X350's is 10% completed kits.

**Engine, engine mount and electronics are excluded in the standard kit, however  they can be supplied.


X350 Gen II is Personalized to Suit Your Taste



A full-leather interior, generously crafted seats (with perforated accents), leather on the instrument panel and the inner lining of the doors, as well as black leather trims, is an elegant and sporty result; which fits perfectly into the overall concept of the X350 Gen II.
