![]() ![]() 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. ![]() No aileron setup is needed (aileron goes to neutral when brakes applied). Landing the Prestige 2PK is easier than ever. Flying in full camber in the same conditions gives values in the range of 0,25-0,3m/s but less area is covered. That means search mode for thermals is very efficient and a fantastic glide ratio. 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). 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. Now you can change camber at any point without loosing flying energy like we see in many airfoils. The large and newly designed rudder makes it possible to yank the model into any thermal you find.Īs 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. This means high bank angle is possible and yet still keep the high lift in a tight thermal. There should be no need for extreme joiners though this is again a personal preference.Ĭircling 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). It has also been flown a lot with 5 degree joiners with good success in low altitude thermalling at EC F3J 2019. It was first produced with 6 degree tip joiners and then we added an 8 degree alternative. 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 is worth mentioning a few properties we have found very nice after flying this model for a while. This technology creates a light, strong and stable platform for years of flying. To this we added the full rohacell core to the design, the whole model is made in heated aluminum molds to a very high temperature. ![]() 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.
