The Mohawk was a single seat twin engined high wing mono¬plane with conventional three axis control. Wing has unswept leading and trailing edges, and constant chord; two fin tail. Pitch control by elevator on tail; yaw control by fin mounted rudders; roll control by half span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from below by struts; wing profile; double surface. Undercarriage has two wheels side by side with two additional tail-wheels; steel spring suspension on tail-wheels and glass fibre suspension on main wheels. Ground steering by differential braking. Brakes on main wheels. Composite construction fuselage, totally enclosed. Engines mounted at wing height driving tractor propellers.

Conceived by Bobby Baker, the prototype of this composite construction machine made its first flight in November 1981. Using aluminium, foam and glass fibre in its construction, the Mohawk became available at the end of 1982 in the form of plans ($100) or a kit requiring 400h completion time, the kit costing $1750 without engines.
However, the company’s plans for this distinctive twin engined twin boom machine included marketing a factory built version and it is clear from the design of the single engined Mohawk X that it has been engineered with series production in mind. The Mohawk can be towed on its own undercarriage, allowing a set up and break¬down time of 20 min by two people.
The Mohawk X is similar to the Mohawk except single engined and fitted with flaps. Undercarriage has three wheels in tricycle formation with two addition¬al tailwheels. Engine mounted at wing height driving pusher propeller.
This is basically a single ¬engine version of the original Mohawk with tricycle undercarriage. The X series has a 430 Cuyuna engine driving a larger pusher prop through a 3/1 reduction unit and short extension shaft. It also incorporates a retractable nosewheel and the cockpit well set forward of the original location to compensate for the aft engine. A conventional flap arrangement is incorpo¬rated in the inboard wing panels and the wings pivot and fold back along the booms for a 5 min assembly time requiring one person. Totally re engineered internally for faster production methods, the X uses wing spars and tail booms of aluminium tubing as opposed to the built up units in the prototype Mohawk. The craft is available in two forms from the factory, first shipments to dealers being scheduled for April or May 1983. The first option is a quick build kit requiring about 60 h assembly time; Bobby Baker says this is mainly a matter of pop riveting and bolting with little glueing or glass fibre work required. This price is estimated at $5800. Alternatively, an almost ready to fly aircraft is offered, requiring only that the tail boom assembly be bolted on and minor rigging done, a total time of less than 20 h. List price of the Mohawk X in this form is estimated at $6800.
