The all-new Freewing Twin 70mm SR-71 Blackbird is a beautiful model. This model assembles quickly and has a board pre-installed to premix all of your aileron and elevator functions right out of the box. This model includes 3 graphic options for you to choose and apply via water slide, while having the "no steps" pre-applied. You will need an 8 channel receiver for this model to utilize all of the available functions, but can get away with as low as 6 channels if you choose not to use the reverse thrust and parachute options.
