Team Tango Foxtrot

Foxtrot 4


The Tango 2 and Foxtrot 4 wing uses a constant chord, constant thickness airfoil which gives it gentle, textbook stall characteristics. Wing root first, ailerons last, with no built in twist required. The stall itself is simple with distinctive aerodynamic warning and little to no tendency to drop off. Differential ailerons counteract adverse yaw.
The wing spars are factory assembled. They are a one piece composite I-beam structure that goes from wing tip to wing tip. Both airplanes were designed to 6/-4 G's and have been successfully tested to 1.5 design limits. Each wing and horizontal stabilizer spar is tested to 6 G's before it leaves the factory.

All of the fuel is carried in the wings. There is no fuel storage anywhere in the fuselage or engine compartment. Capacitance type fuel probes run the entire length of the wing. This allows accurate fuel quantity readings from full right down to zero, a rarity in many airplanes. Total unusable fuel is less than a pint. The fuel selector is in plain view on the forward console and is easily accessible for switching from left to right. The large capacity tanks provide a reserve even after a four or five hour flight.

Team Tango uses only FAA approved foam core in the structures. It is more expensive, but compared to other popular foam cores it is the only one that does not create cyanide gas when exposed to flame, is self extinguishing and fuel proof. The Tango and Foxtrot both feature a dual gull wing canopy system which incorporates a reinforced roll bar. Both can cruise at 200+ mph, have a range over 1400 s.m., carry over 100 pounds of baggage, and operate off a grass strip.

The fuselage sits level in cruise flight which is three degrees lower than the ground attitude. The molded fiberglass seats put the pilot and passenger in a semi-reclining position leaning back approximately 30 degrees. The Tango and Foxtrot are 44 and 46 inches wide. Various antennas are installed into the fuselage during the lay-up process, when it is easy. The instrument panel is divided into three sections. This allows easier installation and access for maintenance and upgrades.

The fuselages use quarter inch foam core that is reinforced at the horizontal stab attach points and up into the vertical stab. A build center is available to build your airplane at the factory, guided and instructed by the staff, and that expertise is included in the price of the aircraft. The seat installation is adjustable for leg room and height as well as recline. The airframe can be customized. The wing can be longer to reduce wing loading, reduce stall speed, climb better at lower airspeeds and have greater high altitude performance.  They use ½” foam core in and around the doors ensure stiffness so they won’t pull away from the fuse in flight and cause air leaks or allow rain to enter the cabin. A vinyl ester resin in the composite is a safer and less toxic alternative that won’t induce an allergic reaction and is pleasant to work with.
