ULTIMATE 300KS Mk2 39%
Dear customer,
thank you for choosing ULTIMATE 300KS Mk2 39% model airplane.
Original kit Ultimate 300 KS was developed by our team for patern and 3D flying too. Kit has had
great flying characteristics, but not sufficient for top competitive flying. We decided to improve it's
flying characteristic and in cooperation with great Italian pilot Sacha Checconi was created new
version Mk2 built on strong base of current kit and test it with our pilot Marek Plichta.
And what are the differencies?
At first, we put close together top to bottom wing and engine axis is now right in the middle of the
wings. At second we enlarged ailerons on all wings at depth and lenght too, overall area is now
bigger to original more than 60% ! Kit gets uncredible flying agility also during harier tricks. We
also decreased overall weight at the same time reinforced wings (new wing spar) for higher drain
during aggresive 3D flying . New is fixing of cabane inside the fuselage, new interplane struts , new
holder of tanks and already instaled rudder servo tray. Holder of main landing gear is also
redesigned, Gabriel horns are used on all control surfaces, as well as new builder friendly servo
fixing on the wings.
The ULTIMATE 300KS Mk2 kit is a full composite biplane kit, with main top wing from one piece
and bottom wings a horizontal stabilizator spar made from carbon fibre tubes. Both wings and
horizontal stabilizator can be easily removed for transporting. Tail control surfaces has central
hinges.

According to model specification we expect, that this airplane is assembled by experienced user, which will use his habbits and skills to finish it.

  • Page 3: Setting And Setup

     please take into count that there are a lot of carbon fiber in your model, make sure that your receiver has full signal KRILL model takes no responsibility for damages incurred during the assemblying, flying, using or transporting this model airplane.

  • Page 4: Recommended Servos

    4. Recommended servos: You can use any strong and fast servos in standard size. Recommended torque: min 25 kg/cm Recommended speed: 0,08 – 0,11 s5. 5. Assembly 5.1 Empenage 5.1.1 Rudder Firstly you must shorten the pegs of Gabriel horns 6/27 to the lenght 13 mm. Than glue in horns into the prepared holes using an epoxy resin.

  • Page 5: Horizontal Stabilizator

    5.1.2 Horizontal stabilizator Two operation for horizontal stabilizators is needed. First is to place the servo and drill the hole for servo lever. Make sure that lever has enought space for full movement. Otherwise the lever can damage stabilizator surface! Second operation is to secure horizontal stabilizator against motion.

  • Page 6: Elevator

    5.1.3 Elevator Use Gabriel horns 6/20 size from accessories. Glue it to predrilled holes on both elevators. For linkage use Secraft turnbuckle ALU pushrod 60 mm long, from one side is mounted Secraft ball link M3, from second original Gabriel ball link, overall lenght of the link is 80 mm. 40 mm ALU Secraft V2 servo arms is used there.

  • Page 7: Wing Assembly

    5.2 Wing 5.2.1 Servo install First, we will schedule the cables of individual servos of the ailerons to the receiver / central unit. The cable of the servo of the left upper aileron is led through the shaft into the hole in the lower part of the cover in the space of the inter-wing strut (for easier routing of the cable, a string is prepared here).

  • Page 8: Linkage

    Installation of servos in the upper as well as in the lower wings is now very simple, thanks to the new servo holder with an integrated servo shaft cover. The servo is first mounted in the individual holders / covers, it is best fitted with a 40 mm long Secraft arm. Center the lever in the middle position.

  • Page 9: Fuselage

    5.3 Fuselage The installation of the internal equipment of the fuselage of the model is very individual, it depends on the habits of the builder, but especially on the equipment used, consider the following lines as informative, what the internal installation of the fuselage may look like. The model comes standard with a number of accessories that you can use: - Exhaust holder - Tank holder...

  • Page 10: Engine Installation

    5.3.2 Engine installation The MVVS116NP engine was used for the model prototype shown. You can use any engine (2- cylinder boxer) size about 100-120 cc. The engine is mounted offset to the right 2.5 degrees, horizontally at zero. It will probably always be necessary to mount the engine using spacers of suitable length so that prop hub plane is about 2-3 mm in front of the engine cover plane and respects the engine misalignment, ie the engine axis at the prop hub level intersects the vertical axis of the model fuselage.

    5.3.3 Fuel & Smoke Tank installation To install fuel and smoking tanks, you can use the standard delivered holder designed for use with Secraft square tanks - SE Fuel tank 1000 ml. The picture below shows an installation example. The tanks are attached to the holder with velcro...

  • Page 12: Equipment Installation

    5.3.4 Equipment installation No deck is installed in the fuselage to install the electronics inside the Fuselage of the kit. Due to the small dimensions and weight of the receivers, their satellites and powerboxes, it is possible to stick them to suitable places directly on the inner walls of the model using double-sided adhesive tapes and velcro.
  • Page 13 The legs of the landing gears are delivered already drilled with the fuselage of the model. All you have to do is install the wheel axles and fit them with wheel covers. First, make sure that the wheels you plan to use pass through the holes in the wheel cover. If not, you can slightly enlarge the holes.
  • Page 14 cover before final tightening. The last operation is to put on the cover of the landing gear leg, the cover should be fixed to the fuselage with a strip of transparent adhesive tape. 5.4.2 Tail wheel assembly We recommend using our tail wheel 2010300-81 Tail wheel 35% with leg of C / F V2 for the model. Attach the tail wheel to the tail of the fuselage on a designated area, which is reinforced inside with plywood.
