Pulsar Pro 2.5e

The new Pulsar Pro 2.5e is a stretched version of the excellent Pulsar Pro 2e electric R/C soarer. The Pulsar Pro 2.5e is a very light high tech full house 2.5m electric glider that is great for sport flying. It uses the latest Ukrainian composite construction techniques married to a modern aerodynamic design with a wing utilising Mark Drela's slippery AG25 airfoil for best thermal duration performance. The low wing loading enables excellent thermal climb performance, with fully articulated wing controls allowing the model to be centred accurately in small turbulent thermals. The thin low drag airfoil works well over a surprisingly large speed range, allowing the model to be safely brought back after drifting far downwind.

The Pulsar Pro 2.5e fuselage pod is beautifully molded from Kevlar with a large canopy hatch to give easy access to the powertrain, battery, and RC. The boom is a lightweight carbon molding with a molded tailplane mount and a bushed holes for mounting the vertical stabiliser. The tailplane and fin/rudder assembly are both removable for easy storage and transport. The rudder and elevator servos are mounted in the fin, to simplify the RC installation.

Like other quality thermal soarers the Pulsar Pro 2.5e is constructed using free-flight techniques. The three piece wing is a balsa built-up carbon fibre and Kevlar D-box design that utilizes carbon capped balsa ribs and a carbon trailing edge. All the flying surfaces are expertly covered in Oracover Light, and all the control surfaces have been nicely hinged. An unusual feature of this model is that the centre panel isn't flat, it incorporates some dihedral, which is added to in the tip panels. This improves the efficiency of the wing and raises the dihedral break, reducing the likelihood of ground looping when landing.

The best use of composites, combined with a high quality design ensures a lightweight and rigid structure. This high performance model is perfect for the sports flyer who wants to experience top level performance with a reasonably compact and tough airframe.
