Introduction The Mega Fusion was the natural progression from the Fusion. It can be used for a large model trainer or glider tug (with appropriate alterations) as it provides a stable base which a pilot of any experience will enjoy and feel confidence with. Wind up the rates and put a hot motor in it then like the Fusion it will loop on the spot, roll in the blink of an eye, again, inspiring confidence as it remains rock solid and stable.

Building Instructions Fin and Rudder Take the 7 parts that form the Fin (Parts 43(2), 44(2), 45(2) and 20), sandwich the ply part between the sheets of 1/8 balsa Take the four parts that form the rudder (Parts 30, 32, 33 and 42) and assemble as shown below using the 12.5 x 9.5mm (1/2”...

Tail Plane parts laid out Tail Plane assembled Riblet pieces inserted Use the 1.5 x 6 x 915mm (1/16 x 1/4 x36”) balsa strip and glue it in the pre-cut spar slot flush with the surface, insert the 5 x 450mm (18”) carbon spar and glue in place with epoxy before capping with the remaining strip.

Glue the two F1’s (Part 22(2)), two Wing Bolt Plates (Part 9(2)) and two Wing Dowel Supports (Part 14(2)) together to form 6mm (1/4”) thick parts. Insert the two captive nuts by using a hammer on a flat surface. If you are building the Petrol Version your kit will have a 6mm (¼”) Birch Ply F1 to replace the two 3mm Poplar ply pieces.

If you are building the electric version take the battery hatch floor (Part 10) and place the tab in its slot. Do not glue it into position. Plank with the 3mm (1/8”) balsa sheet from the rear of the battery hatch floor to the back of the Fuselage. Plank the bottom of the hatch floor with 3mm (1/8”) balsa except for the tab that fits under the U/C mount.

Cut slots in the Servo Mounting Plate (Part 11) to accept your chosen servos. The rudder and elevator servo sit at the rear of the plate, if building the petrol version then mount a smaller servo at the front of the plate for the throttle.

Wing Tube Wing Layout (Left Hand Section, mirror for Right hand section) Begin placing the ribs in the slot in the order shown above. Using a set square ensure that the ribs are at to the spar, and use a ruler to ensure the rib is straight without any deviation. The centre and end rib must be absolutely vertical and straight.
Page 14
Insert the 4.5 x 4.5 x 915mm (3/16 x 3/16 x 36”) spars into the leading edge slots, check the end ribs before gluing. Once dry gently sand so that it is flush with the vertical leading edge. Take the sheet of 9.5 x 75 x 915mm (3/8 x 3 x 36”) balsa and cut in half along its length to form the two leading edges.

Centrally to the top of each exposed rib glue the 2 x 9.5 x 915mm (3/32 x 3/8 x 36”) capping strips from the trailing edge sheet to the leading edge sheet. The end cap strip will be glued flush with the wing tip end rib. Un-pin the wing, be careful as it will still be quite flexible, turn over and re-pin the trailing edge and main spar back onto the board.

Make sure the centre ribs are touching full length Once both panels are complete join the wing using the aluminium tube and test the fitment to the fuselage, make adjustments where required to the fuselage cut out or the profile of the wing. Ensure that the wing is central on the fuselage, push one of the dowels through the holes to leave a mark on the leading edge, remove the wing and drill an 8mm hole where the dowel marked.

Repeat the above stages for the second aileron. Ensure that you get at least 45° free movement either way. Do not glue the hinges in at this stage! Cover both parts with your chosen covering first. Sand to provide a smooth, blemish free surface ready for covering. Covering Before undertaking the covering seat the wing, tail plane and fin and make sure that all fit.

Cyano. Ensure the Cyano penetrates through the cotton. Final Assembly If you have any queries about the final assembly then please contact us at support@evolution-models.com where we will be happy to discuss your problem and send you a photo or two to illustrate our solution. Wing Take the fully covered wing and ailerons, glue the hinges into the aileron using epoxy.

making sure the horn remains at 90° aileron leading edge. Once satisfied that the horn is secured run some Cyano onto the thread to ensure the nut cannot be loosened. Cut the threaded rod to the correct length before soldering on the threaded extender as shown below. When correctly fitted the clevises should be threaded onto the rod so that it can be threaded in or out an equal amount.

Glue the Tail Plane into position, apply the glue inside the slot, top and bottom, and with help carefully open t he slot while inserting the Tail Plane and release the Fuselage to clamp back down. Only apply slight pressure so as not to break the rear of the Fuselage. When inserting the Tail Plane be careful not to get glue onto the covering.

Make up the closed loop systems to the Elevator and Rudder as shown below. Use an M3 nut to lock the clevis onto the closed loop extender. Make sure that the horn is suitable to take the loads imposed by the surfaces.

the model is in flight. In a model this size we would recommend using a separate UBEC or receiver battery for safety Control Throws We only recommend setting the model up with sport flying throws unless you are an experienced flyer. Increasing the control rates will make the model extremely responsive! For test flying and sports flying, set the control throws up as shown below: Ailerons - 65mm Up and Down measured at the tip...
