The Tango F5J
is a very nice 3.15m four servo wing (flap and aileron) all CNC cut wood kit. The wing uses carbon tubular spars to facilitate quick and accurate construction, and the CNC parts fit together like a beautiful giant jigsaw. Two carbon tubes per wing make it extremely torsion-resistant and allow the Tango to be flown on windier days with impunity. The large span, optimal aspect ratio, and HQ30/11 airfoil and full span control surfaces give the Tango an excellent glide angle and duration. Adding a little camber allows the models to thermal beautifully, so it can climb in even the weakest lift. The Tango is easy to master and the landings are child's play with the big flaps. The landing approach can be nearly vertical! If the flaps are set to 90° the Tango sinks safely very steeply and can be rounded out and alighted on the spot with ease.
But who is talking about landing? We want to fly the Tango does that very well. Even with normal flap position, the Tango thermals well. With the flaps in thermal position it's even better. When travelling back upwind raise the flaps a bit and the Tango pickings up speed without losing height.
The Tango really likes to circle tight. After the development and before the serial production of the models the manufacturer built several models to really verify the data. They found the Tango can fly very slowly but also has a wide speed range. It was built to circle in the thermals and to land accurately. Both are possible to perfection. The 4 control surface wing can be adapted to any desired situation. Modern programmable transmitters offer countless possibilities.
