With over 18 months invested in the design, the Katana MD™ is the first model to be built using the new and revolutionary building technique – PA FiberFusion®.
FiberFusion® is a method of combining carbon fiber, balsa and ply in a way never seen before, utilizing the strengths of the fibers within each raw material, with the end result being lighter, stronger, more rigid aircraft that fly like nothing else!
For maximum aerodynamics, the aileron design and construction in this model is exceptional, made in such a way that the hinge gap is completely sealed. This is quite complex to produce: the ailerons fit into the wing trailing edge tunnels and are glued and aligned in the factory. Despite the laborious production of this design we decided to produce the ailerons this way, as it allows perfect aerodynamic flow over the airfoil and results in maximum efficiency of the control surfaces.
Needless to say, the Katana MD™ is built using finest grade material, all cut by state-of-the-art laser and CNC machines. As any other PA model here too the two wings are removable with a CF wing tube and a CF sleeve which make the Katana MD™ a compact, durable, and easily transportable model.
The Katana MD™ is not an enlarged version of the Katana Mini. Rather it is a new aerodynamic design with the strengths of the Katana Mini incorporated in it along with many new features. The combination of the design and the innovative construction technology grants an outstanding model, which will simply out do other planes in the same size category.
The Katana MD™ is a freestyle machine. It is designed for advanced and professional pilots, not for a beginner. In the hands of a professional pilot the Katana MD™ will perform miracles. If you feel that you have graduated from the Katana Mini, this is the plane for you. If you want to practice your IMAC sequence the Katana MD™ is your best choice - its flight characteristics are very similar to a giant scale. And if you want to practice your 3D maneuvers - simply slide the battery aft to the recommended CG and you’ve got it made.
So how does it fly? Solid elevators that will knock you down (put it this way, push full down elevator in inverted flight and you can take a nap). Stunning knife edges with close to zero coupling (only one click of rolling coupling with zero pitch coupling). Due to its super-light weight, exceptionally low wing loading and the design factors this plane is a serious floater. Harriers and elevators with a few clicks of throttle are hands off.
This ARF redefines the word QUALITY through and through, from the design to the construction, the hardware and the level of finish. The attention to detail is second to none. The wings are matched individually to each fuselage just like we do on our giant scales and the model is 99% built for you in the factory:
The brief assembly is a joy and most modellers will have it set up in one evening.
Carbon fiber features
Vox 13x5 -This is our first choice with the Katana MD along with the optional Vortex Generators (VGs) installed. The Vox 13x5 with the Thrust 30 motor are excellent combination for extreme 3D and freestyle specifically tuned for slower and graceful 3D. The added thrust provides good traction when flying slow 3D such as slow harrier rolls and slow KE and the excellent propwash provides extra stability in AOA harriers.
It offers an excellent punch for recovery out of awkward situations especially when learning to hover or torque roll. Allows moderate speed maneuvers with a “giant scale like” overall appearance to the maneuvers. NOTE: Adequate airflow to cool down the motor and ESC is mandatory, as well as throttle management.
We made a few videos of this combination (Vox 13x5, VGs, iPAs setup) for you to download (available on this webpage).
VOX 12X7 - Nice overall propeller for aerobatics and pattern flying providing more flight speed for high energy maneuvers with longer flight duration than the APC12x6E due to the higher efficiency. It resembles the performance of the APC12x6E but with better efficiency and 3.8A lower current drawn, plus it has the sleekly wooden appearance ;)
