When will G1 STOL be available to purchase?
We are currently delivering Kits and RTF. We just received compliance with the 51% rule for Amateur Built in Canada. We should receive reciprocity from FAA in a short time.
What is included in the kit?
Everything you need to complete your airframe is included in the base kit, and we also supply engines and everything else you need to make it ready to fly.
Base kit contents:
Airframe: fuselage, wings, flaps, ailerons, rudder, elevator
Carbon fiber cowling
Doors, windows, windshield (Lexan)
All control linkage and cables
Fuel tanks and lines
Landing gear, brakes, brake lines, tires
All applicable hardware
Parts required to complete the aircraft:
(these are options you will need to add to your order with us, or supply on your own)
Engine, engine mount always included but design fee for alternate engine, oil, coolant
Wiring and electrical components (engine and avionics specific)
Supplies: Epoxy, thread-lock, tape, and other general construction supplies
*If you are buying your avionics from us, we include the CNC cut instrument panel configured and ready for those instruments. Otherwise, you can build your own custom panel out of your material of choice, or request a blank aluminum panel from us.
Other options and upgrades are also available, such as extended fuel tanks, position/strobe/landing lights, floats, etc. See our price list for full details.
What assembly work and skills are needed to complete the kit?
Our Advanced Quick Build Kit comes with a lot of the time-consuming work done, yet still complies with the 51% rule. You will be pleasantly surprised to find things mostly assembled, from the wings and fuel tanks, to the fuselage, the landing gear and brakes, and even most of the controls are pre-installed and ready. The tail is almost finished. You will finish the tail and control surfaces, hook up the wings and control linkage, install the doors, windshield, interior, mount the engine and install your avionics. And don't worry, our build manual will walk you through these steps, and we are here to answer any questions along the way. This is intended for anyone to be able to assemble, but the ideal builder should have some technical ability.
We are striving for the fastest built kit for this class of aircraft in the entire industry! If you love building, but also want to actually fly your plane within a reasonable timeframe, this is the kit for you!
Will there be sub-kits?
No. The nature of our kit doesn't necessitate splitting into multiple sections. The build time is not long enough to require spreading the stages out. We also prefer to save our customers the cost of multiple shipments and handling.
Will there be an SLSA ready-to-fly option?
We plan to offer the G1 STOL as a LSA in the future, but assembled LSA planes are not being sold at this time. Follow us on our Facebook page (or check back here) to keep up to date on any news or changes regarding this.
What engines are supported?
The design, including engine mounts and cowls, currently support the following engines: D-Motor LF-26 and LF-39, and Rotax 912iS. We may be adding others in the future. Builders are welcome to try alternative engines of their choosing and we are happy to provide the detail needed to calculate CG and other factors. Custom mounts and possibly custom cowlings would be needed. Ask us how we can assist in this area.
What tires are supported?
We are working to determine this. Right now, the spec is for 6" to 8" wide, and 13" to 15" tall tires. For larger tundra tires, testing and possibly modifications need to be done. Builders are welcome to experiment, bearing in mind that tire size affects empty weight, useful load, takeoff, landing, climb, cruise, stall speeds, and more.
Are wheel and floats landing gear easily interchangeable?
Yes. Switching between gear takes about 3-4 hours. Our floats actually attach to the main gear without removing the wheels, using basic tools. They are hydraulically operated, allowing landing in water, or maintained landing strips. For backcountry flights onto rough terrain, you would, of course, want to remove the floats. We also offer basic floats that have no wheels and require your nose and main wheels to be removed.
Are skis supported?
Not today. We may be able to offer this in the future. Builders are welcome to experiment with this on their own.
Is this all aluminum, or does it have fabric covering?
In America, we only offer the G1 STOL in all aluminum. In France, the G1 comes default with Dacron covering on the control surfaces, while the fuselage and wing is aluminum covered.
What is the benefit of a folding control stick?
The G1 comes with dual center sticks that are completely foldable and out of the way, stowed flat to the floor when not flying! Folding is quick, easy, and requires no pin or screw removal. Now you have clutter-free access to get in and out of the seat very easily, and while loading, unloading, or doing maintenance in the cabin. If you prefer a center stick as a pilot, but also want the convenience of a clutter-free cockpit while on the ground, this is a great feature!
How many G1s are built and registered?
In Europe and Africa there are about 150 G1's flying and more in process of being completed. Customers vary from private owners, to commercial and agricultural businesses, and governments (police, etc). These planes have a great track record of reliability for over 25 years since the original design, and over 10 years on the latest updated design. We look forward to seeing these build numbers grow as it is finally being made available in America!
Is there support for disabled pilots?
Yes. An optional system is available, enabling pilots to control the rudder without the use of legs. Brakes are operated by hand for all pilots, with the option of being on one or both control sticks, or as an independent lever between the seats.
Is G1 STOL a copy of a Zenith CH 701?
No. The G1 is derived from the Italian-made Alisport Yuma (1994), and even that original design was unique and distinct from a CH 701. The swept tail on a tricycle gear STOL configuration, and tapered wing root to allow for sun-roof visibility, are similar traits both the CH 701 and the G1 share, but that is about it. In fact, the G1 is much bigger than the CH 701, it is clearly not a copy.
Inside and out, the G1 STOL has different construction and build process, from the welded cabin tubing, to the contoured (not boxy) fuselage, different rudder, different elevator, different wing (airfoil, foldable, no slats, G1-specific vortext generators), different controls (dual center sticks, foldable!), different landing gear, and more. Other feature differences include a strut-based nose gear to damper impact, less noise (airflow of more streamlined fuselage), bigger dashboard, fishing rod compartment, and an integrated parachute compartment. Specs of the G1 are of course different too, such as a much wider 48" cabin, and other aspects considerably better for the modern STOL pilot today.
Bottom line: You might find that parts for Avid Flyer, Kitfox and even Highlander are interchangeable with each other, but that is simply not possible between Zenith and G1 due to the completely different designs.
Isn't tail-wheel better than nose-wheel landing gear for a STOL?
We can't answer this because it totally comes down to preference. What we can tell you is that nose-wheel STOL planes have been around for years, impressively getting into just as tight of places as tail-wheels. The G1 tail is very high, allowing the nose to remain off the ground much longer and higher than a typical nose-wheel design. From the beginning, G1 was designed for mountain flying. There are stone deflectors available for wheels.
Many pilots appreciate the ability to handle more crosswind in a nose-wheel, and report appreciation for lower insurance costs as well. At the end of the day, you just have to identify what is important to you. Both nose and tail wheels are great designs providing a lot of STOL joy for pilots.
