Product Code: PM-K8B-6M

Phoenix Models K8b - 6m ARFT

The Phoenix Models 6m K8b is a very keenly priced ARTF almost ready to fly 40% scale model of the popular Alexander Schleicher Ka 8b. All our K8b models have the new stronger wings. These are easily strong enough for aerobatic flight. The structural integrity of the model is guaranteed.

The K8 is the slightly better performing -b version with a bubble canopy. The scale model includes a pilot figure to look the part when in the air. The ARTF model has been expertly constructed from laser cut balsa and ply and is covered in white and red Oracover (Profilm) to a very high standard. The only work required to get the model in the air is installing the RC.

Although this nearly half scale model it is new to the UK, there have been many very positive flying reports from Germany, Australia, and the US. It is comparatively light and thermals beautifully - just like the full size aircraft. All these qualities make it an ideal first giant scale model for any aspiring RC pilot.

To alleviate transport and storage difficulties the wing is a four piece design, with each wing (left and right) breaking down into an inner and an outer panel. Our kits all include the stronger inner wing panels, following a problem with one of the original models in the US.

The UK delivery cost is only valid for the main UK conurbations, excluding country areas and Highlands and Islands. Sorry, but this model is too big to be shipped to overseas buyers. Due to the large size and not-very-strong box we much prefer if this model is collected from our Warwickshire warehouse.
