Prestige 2pk

The Prestige 2pk is the new release from Samba Model designed by Philip Kolb. The Prestige 2pk is a carbon fiber glider with full rohacell core. 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.
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
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. 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 very easy. 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 nose is available in 32 mm and 30mm diameter. It is designed to fit cheap and reliable outrunners for lighter versions. 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.
The Prestige 2pk is available in 2 tail versions, X-tail or V-tail.

F5JPro Models Review

review
Hello guys,
Firstly, I am hoping you are all staying safe and healthy during this challenging period. Last month was a pretty taught time for me as I received the Prestige 2pk models and had to do training and still be able to have your orders ready on time. An announcement I would like to make is that I will be flying and representing the Prestige 2kp in future competitions.
Flying this beautiful model led me to some observations that in turn motivated me wanting to share that with you. I had a first time experienced doing so many flights in a month in several different conditions and places. In the timespan of the previous month, I had the opportunity to visit a different field than that I usually train at, which is flat and test the Prestige 2pk along the tree lines. In order to test the model on weak thermals and dead air I preferred to visit the field early in the morning and late in the evening. I, of course, had the chance to test it on calm conditions with thermals but I also did flight it in windy weather many times.
One of the leading factors that made this model great, was the combination of low circling and penetration capabilities. After all those flights, I figured out the Prestige 2pk performed greatly in dead air, covered a good distance without losing much height and its speed was more than enough for coming home from far away while also being useful in getting away quickly from the sink.
I’m very pleased with the circling stability of the model and deeply in love with its tail (x-tail), as it adds a great effect. The big rudder can give you a solid boost of energy when you need it and it also helps you define the exact positioning of the model on long distance or due to impaired visibility situations. The Prestige 2pk model can perform a pretty tight circle helping during the plane’s climb from low height. Most importantly this model can climb FASTTTT! This plays a pivotal role because a faster ascend means fewer possibilities for pilot mistakes that may result on the compromise of the total height gain. Thus, categorizing the Prestige 2pk as somewhat of a <>model that doesn’t lose much height when the pilot do mistakes. That makes it particularly appealing to me!
As I previously said, I visited the field with the tree line and I attempted to play off them on windy conditions, checking the model’s ability to perform a kind of slope flight. I can comfortably state that this model is more than capable of performing such maneuvers. In other words, can use the trees in order to achieve that excess time that is needed in competition or just for the rush. Additionally, the flaps are more than enough for the coveted 50 points or generally for the landing.
Regarding the manufacture, SAMBA Model has done a great job as the surface of the model is shinny and strong enough. A top quality plane! I would only a slightly bigger canopy hole but that doesn’t seem to be a problem with a little sanding right and left, so you can fit all the popular lipo batteries. Btw, our batteries Tattu R-Line just need 2mm. of sanding to fit perfectly in the nose.
I still need time to connect more with the plane and learn with it but I’m really hyped about my new models. Nevermind the competitions being closed and the European F5J Championship also being rumored to be, in which I was chosen to represent the Greek National Team, it’s now time to put my head down and focus on training.

Thank you for your time.
Nikos Danavaras
