** Prestige 2PK wins Radioglide 2021 & The Nationals 2021..! **

First of all thanks to Philip Kolb for constructing an exceptional model in the F5J world. He was not influenced by various fads in the F5J world and used all his knowledge, experience and best available software to construct the amazing PRESTIGE 2PK.

For the P2K Samba have used full rohacell core for the design and the whole model is made in heated aluminum molds to a very high temperature. This technology creates a light, strong and stable platform for years of flying.

Circling
In circling the model as expected did not have a need for extreme dihedral joiners since the aerodynamic design and airfoil changes does that work in a better way than increasing dihedral. It was first produced with 6 degree tip joiners and then we added an 8 degree alternative. It has also been flown a lot with 5 degree joiners with good success in low altitude thermalling at EC F3J 2019. There should be no need for extreme joiners though this is again a personal preference.

Circling camber can be extreme (5-8 degrees) while still maintaining speed during because of a new tail design that keeps the energy better (less drag). This means high bank angle is possible and yet still keep the high lift in a tight thermal.

The large and newly designed rudder makes it possible to yank the model into any thermal you find.

Penetration
As you will find described in the designer Philip Kolb’s writeup the penetration in all camber settings is very good because of the new tail design. Now you can change camber at any point without loosing flying energy like we see in many airfoils. The model now just speeds up to the desired speed/camber setting and keeps that for a trip over the whole airfield thru lift and sink. Night and early morning testing have shown sink values as good as 0,35-0,4m/s in distance mode (1mm up along the whole trailing edge and measured by altimeter). That means search mode for thermals is very efficient and a fantastic glide ratio. Flying in full camber in the same conditions gives values in the range of 0,25-0,3m/s but less area is covered.

Landing
Landing the Prestige 2PK is easier than ever. No aileron setup is needed (aileron goes to neutral when brakes applied). Only flaps and elevator compensation. Still the model slows down to a crawl and pushing over is easy as the new elevator keeps the energy well even with full flaps applied. The rudder is also better and bigger and with the new high dihedral middle and aerodynamic airfoil changes it corresponds well to rudder input and is not as much affected by sidewind as earlier models. Though it should be said that the lightest layup has very light tips and heavier tips (inertia) might be preferred if the landing area have lots of sidewind and/or turbulence.
The nose is removable. It is made longer than needed and can be shortened ( max. 100 mm) according to engine weight and lipo. Install equipment and shorten nose to fit preferred CG. The original nose has a diameter of 32 mm. It is designed to fit cheap and reliable outrunners for lighter versions. Very soon we will produce a nose cone with slimmer diameter of 30 mm.
The servos and receiver are located in the fuselage under the center wing therefore there is enough space in the front for the motor, controller and lipo. Battery size from very small and up to 2300mah can be used as much care is taken to a very thin but almost square fuse in the front area.
The complete wire harness is built into the center panel and the central connector is ready installed. Wire harness for fuselage is also delivered ready made.
