Page 8: Manufacturing And Material Note
Sawn Craft Mana‐Tee Manual A quick note about the manufacturing method and material We have designed this model to utilize XPS foam that has a lightweight paper laminated on both sides of it. The use of this material versus other available options gives us multiple benefits, including a more rigid product as well as one that is more durable for the intended combat‐flying use. To provide the highest‐quality edge finish we utilize a CNC drag‐knife that cuts the foam using a precision blade. The blade is oriented at an angle so you will note that on one side of your foam the cuts have small hash marks that extend beyond the cuts; this is simply a function of the cutter and does not affect the durability of the material. As these marks are not necessarily the nicest‐looking, we have oriented the parts such that they will be hidden when the model is completed. In order to maintain the integrity of this material, care must be taken to either not get the foam wet (including painting with water‐based paints), or if that is not possible, coat the entire model in oil‐based polyurethane prior to flying to protect the foam. We have flown countless flights with our test models built of this material and with a little bit of care there have been no issues. We do recommend either taping the leading edges of the model or using a thin coat of Foam‐Tac on the edge of the foam to protect the exposed paper from delamination. If you have any questions about the material or our manufacturing method please don’t hesitate to contact us and we’d be glad to chat! Page 4 150301 Mana‐Tee Manual.docx ... -
Page 9: 2 Assembly Instructions
Sawn Craft Mana‐Tee Manual 2 Assembly Instructions The order of assembly presented in this instruction has been tested and it is recommended that you do not differ from them to provide the most accurate and easiest assembly possible. 2.0 Main Wing Assembly • Parts Required: o Main Wing Front o Main Wing Rear Due to changes in our packaging, we were forced to modify the main wing and this step covers assembly of the two main wing pieces into what will be referred to as "Main Wing". 1) Carefully remove the Main Wing Front and Main Wing Rear from their respective sheets. Lay both pieces on a flat building surface with the paper score cuts facing up. 2) Apply glue to the mating edge of one of the pieces and assemble. When the glue has cured, peel the paper off of the scored areas nearest the glued seam. If desired, apply one strip of clear packing tape over the seam to make the joint seamless.

Page 10: Parts Preparation
Sawn Craft Mana‐Tee Manual 2.1 Parts Preparation 3) Parts Required: o Main Wing o 2x Fuselage Half o 2x Vertical Stabilizer o Fuselage bottom o Mana‐Tee 1/32”Plywood Battery Box Side (2 each) o Standard Control Horn (4 each) Lay the main wing on a flat building surface with the knife hash marks facing up. Peel the thin paper strips off of the foam where it has been scored for the fuselage to mate with it. This side will now be referred to as the bottom. This will give the glue a place to make a foam‐to‐foam bond which is stronger than foam‐to‐paper. Lay the vertical stabilizers with the hash marks facing up and peel the thin paper strips off the foam for the wing to mate with it. Lay the fuselage halves with the hash marks facing up and peel the paper section off of the front part of the piece, where the battery box will mount. Lay the fuselage bottom with the hash marks facing up and peel the thin paper strips off the foam for the fuselage sides will mate with it. Use a hobby knife to carefully cut the control horns and battery box sides from their material skeleton. Take the 200‐grit sandpaper and smooth the holding tabs and the edges of the parts.

Page 11: Control Surface Installation
Sawn Craft Mana‐Tee Manual 2.2 Control Surface Installation 4) Parts Required: o Main Wing o Elevator o 2x Ailerons Warning: This process involves using extremely sharp cutting blades. Care must be taken to avoid injury. Lay the elevator on the table with the leading edge facing you and the control horn slot to the left. Use a hobby knife to cut a ~45° bevel into the leading edge of the elevator. Lay the aileron on the table with the leading edge facing you. Both ailerons are mirrors of each other so orientation (L or R) doesn’t matter as long as you cut the bevel properly for the side. Use a hobby knife to cut a ~45° bevel into the leading edge of the aileron. Repeat for the other aileron. Place the main wing on the table with top side up. Align the ailerons and elevator to their locations with their bevels facing down. Using Blenderm tape, apply 2x 2” strips to either end of the control surfaces. Flip the assembly over and apply 2x 2” strips of Blenderm again to either end of the control surfaces, being sure to get the tape down into the bevel. Page 7 150301 Mana‐Tee Manual.docx ... -
Page 12: Kf Step Installation
Sawn Craft Mana‐Tee Manual 2.3 KF Step Installation 5) Parts Required: o Main Wing o KF Step Warning: This process involves using extremely sharp cutting blades. Care must be taken to avoid injury. Lay the KF step on the table with the hash cut marks facing up. Peel the paper completely off this side of the part. Lay the bare foam side of the KF step on the top of the main wing, aligning it with all of the edges. With a pencil, gently trace a line on the main wing where the trailing edge of the KF step is. Remove the KF step and use a straight‐edge ruler and a hobby knife to lightly cut just the top layer of paper. Once cut, remove the paper that will be below the KF step. Spread an even coat of Foam‐Tac on the foam side of the KF step and glue it to the exposed foam of the main wing, ensuring to line up all edges. Optional: You may bevel or round the leading edges of the wing to your liking. Page 8 150301 Mana‐Tee Manual.docx ... -
Page 13: Carbon Spar Installation
Sawn Craft Mana‐Tee Manual 2.4 Carbon Spar Installation 6) Parts Required: o Main Wing Assembly o 24” Carbon Tube Lay the main wing assembly on the table with the KFm step facing down. Apply a bead of glue down the entire length of the slot where the carbon tube will be installed. Insert the carbon tube into the slot with a gentle twisting action in order to coat the entire rod with glue. Ensure the tube is sitting evenly in the slot and is flush with the bottom surface of the wing. Allow the glue on the entire assembly to cure before proceeding. This is an ideal time to decorate the parts as they are still flat and will be easier to handle. We recommend using colored packing tape as it will add strength and durability as well as vivid color.

Note that the holes are drilled such that they will be on the lower side of the mount when installed. Insert the blind nuts into the holes that correspond with your motor of choice. Insert the 1/32” battery box pieces into the slots such that the curved edge is flush at the front with the bottom of the firewall. Use thin or medium CA to secure the battery box pieces to the firewall. The completed assembly is shown. Peel the paper off of both sides of the battery tray and the battery spacer. Apply Foam‐Tac to the battery spacer and install it in front of the aileron servo such that it is centered side‐to‐side and is touching the front of the servo. Apply Foam‐Tac to one side of the battery tray and glue it to the battery spacer and the bottom of the aileron servo. Again, ensure that the tray is centered side‐to‐side and is touching the elevator servo. If desired, you can apply packing tape to the battery tray on one side to give a solid base for mounting Velcro for the battery. ... -

Page 19: 3 Setup And Tuning
Sawn Craft Mana‐Tee Manual 3 Setup and Tuning 3.1 Center of Gravity The CG of this plane is located approximately 1.5 to 1.75” from the leading edge of the main wing. Moving the CG fore and aft will dramatically change the handling of the plane so adjust to your liking. An aft CG will allow for slower, high‐alpha flight, but will be more unstable while a more fore CG will provide a faster, more “locked in” flight experience. Use the fore/aft location of the battery to adjust the CG without adding additional weight. 3.2 Control Throws & Expo By altering the amount of control throw the surfaces have you can fine‐tune the handling and performance. Below are the recommended settings as tested that will provide a successful flying experience. Throws are measured at the point farthest from the hinge. Control Surface Low Rate Throw Low Rate Expo High Rate Throw High Rate Expo Elevator 1/2in (70%) 30% 1in (100%) 45% Aileron 1in (70%) 30% 2in (100%) 45% The aileron control surfaces have built‐in differential so they will move more in the up direction than in the down direction. This helps to eliminate adverse yaw. Measure the throw on the ailerons in the up direction. 3.3 Launching Launching this aircraft is very simple and is easy to do. Simply hold the airplane by the fuselage in one ... - Page 20 Sawn Craft Mana‐Tee Manual 3.4 Flying Tips This aircraft is designed to be the perfect “toss in the car” model for most fliers! The compact size allows it to fly in smaller parks, but the speed that it is capable of makes it a great choice for your local flying field as well. With smaller control throws and more expo, the Mana‐Tee is a great choice for newer pilots that are getting their feet wet with aileron controls. Turn the throws up and you get a plane that is extremely aerobatic and will perform axial rolls at an alarming rate! Landing the aircraft is simple; keep some throttle applied and as the plane nears the ground, pull back on the elevator to flare. We developed this model for club combat events and have found many pilots bringing them out on non‐ combat nights because they are just so much fun to fly! When we do fly combat we have used full‐ width (~2”) x 20’ crepe paper streamers attached with tape to the rear of the fuselage with no significant degradation in performance. In the “rare” case that a Mana‐Tee is involved in a mid‐air collision, the reinforced plywood battery box and strong, interlocking construction should provide your electronics and battery protection over other combat plane designs. Remember: Always follow the AMA safety guidelines! Never fly over people or animals. 3.5 Decorating/Finishing The beauty of this aircraft is that you have the opportunity to finish it with the look that you desire. We recommend using colored packaging tape (available on the Building Supplies section of our website) for decorating as it is easy to use, lightweight, and provides a nice, glossy finish. Water‐based paints have been used if the foam had previously been treated with oil‐based polyurethane. Prior to using any paints or markers, test on a scrap piece of foam to ensure that it doesn’t melt the foam. Remember that any weight you add to the airframe will affect its performance so keep heavy applications of paint and decals to a minimum. 3.6 Repairs & Spare Parts Due to this models design and light weight, it is surprisingly durable! If a part of the model is damaged it can typically be repaired using small pieces of packaging tape or by gluing using Beacon Foam Tac. If a part is damaged beyond repair, simply send us an email at Support@Sawn‐Craft.com as we have replacement parts available for purchase. Page 16 150301 Mana‐Tee Manual.docx ...
