The important features that set the AG-915 gyrocopters apart from the competition

Please note that we only offer superior high inertia Composite Rotor Blades. We do not offer extruded aluminum rotor blades, which allow our competitors to offer lower pricing. But lower cost rotor blades, which do not fly as well, and which are subject to metal fatigue and failure, are not worth it, in our experience. The rotor is the most important safety feature of a gyrocopter. In the event of an engine failure, the high inertia of the composite rotor blades makes it much easier to keep flying and to land.

Much More Cabin Space

Carry more - Do More

The AG-915 Spartan, our smaller model, has a cabin that is larger than the competition. And our Javelin model has 25 more cubic feet than the Spartan! (The Javelin is our SUV of the skies.)

When you want to go places and do things, you need room for luggage, or camping gear, or cargo, or scanning equipment, or photo equipment.

Our AG-915 models are designed to be more functional, more useful, and more capable than the two-place gyrocopter competiton that squeezes two passerngers into a cabin, and not much more.

Wider Wheelbase

Greater Stability

With a long rotor spinning overhead, there is a tall force to deal with when taxiing for take-off and landing. The much wider wheel base of our aircraft give you much greater stability especially when taking off and landing on grass or rough fields. You can taxi on uneven ground, and make turns without being so careful of your ground speed.

Wider Horizontal Stabilizer

More Safety

The weakness of early gyrocopters was a problem of "power push over"; engine thrust tipping the aircraft over and unloading the rotor, or leading to pilot induced oscillation (porpoising) as the pilot pulled the rotor back to compensate. Raising the cabin up, relative to the engine, so that it receives center-line thrust is a solution that makes for a tall gangly aircraft. So, the better answer is to add a much larger horizontal stabilizer to solve the push-over issue. Our aircraft have a much wider stabilizer, for maximum stability. Note that the height of this stabilizer is directly aligned with the centerline of the propeller's thrust, to maximize its effectiveness. It is the best solution on the market.

Dual Tail Booms

Stronger tail system

When the whole horizontal stabilizer and tail rudders are mounted on a single bent pipe, there is definitely give and vibration. We mounted a camera on a single tail boom Cavalon and recorded the shaking. Two straight tail booms are much stronger, and nearly vibration free. Our aircraft have rock-solid stabilizers and even have dual rudders for more authoritative control, enabled by the use of dual tail booms.

More Shoulder Room

More Comfort

A wider cabin, with more room between the seats is a major comfort advantage of our gyrocopters. There is also a nice padded armrest between the seats. A hidden advantage of this extra room between the seats is that the center instrument tunnel is so much wider. That makes it so much easier to access all of the control cables and sensor wires. We have spent hours trying to make a fix in the small tube tunnel of a Cavalon, that only takes a minute or two in the wide tunnel of our gyrocopter.

Much Greater Visibility

More Enjoyment - More Useful

The joy and the utility of a gyrocopter manifests itself in being able to see your surroundings. Our gyrocopters maximize visibility with a much larger front windshield which wraps down at the sides, and with windows in the front floor, windows in the roof, extended visibility downward in the doors, and even windows behind the doors. The ability see the runway directly below, through the floor windows, has helped many new pilots judge their landings much better, and master the art more quickly.

More Ground Clearance

More versatile

Grass landings, uneven and rough fields are no problem for our gyrocopters. We have more than double the clearance of the competition, because of our taller landing gear, and also because of our dual tail booms which keep well clear of the ground. Note that the competition, which uses a single tail boom that curves down under their propeller has almost no ground clearance. That tail boom goes much lower to the ground than the cabin, and will simply drag if a field is not pretty even and smooth.

Engine Compartment

Easier to Service - Cooler Running Engine

This is a trade-off advantage that we have come to greatly appreciate. Our partially open back does not look as streamlined as the fully enclosed Cavalon. But the open area eliminates the heat build-up issues that we had with the Cavalon. And their marvel of German engineering, that tucks the engine, turbo, radiators and oil coolers, etc. into the tiny cone of a compartment, turns out to be a nightmare when we are trying to reach components to inspect or service them. With our design, we can see at a glance, the fuel filters and fuel flow. It is amazing how much easier it is to adjust and service the engine because there is so much extra space.
