Page 4: Section 1: Our Recommendations
What Engine Should I Use? The Simply Magic will accept a wide variety of engines, so which engine you choose really depends on how you want to fly the airplane. For general sport flying, a .40 to .52 2-stroke engine with a 10 x 6 propeller (for a .40) or an 11 x 6 propeller (for a .46 or .52) would be perfect. -

Pivot the front of the stabilizer until both of these measurements are equal. When the stabilizer is aligned properly, B should equal B-1.
- Page 15 After the epoxy has fully cured, remove the masking tape and look closely at the glue joint. If there are any gaps between the stabilizer and the fuselage, fill them using 30 minute epoxy for added strength.

Step 3: Adjusting the Wheel Pants With both wheels and wheel pants installed, set the airplane on its wheels on a level surface. Adjust the wheel pants so that the bottom rear portion of the wheel pants are level with the ground. Double-check that both wheel pants are level with each other. - Page 21 Using a ruler and a pencil, measure and draw one horizontal line 1/2" above the horizontal centerline and one horizontal line 13/16" below the horizontal centerline. Temporarily glue the two engine mounting beams to your engine's mounting lugs using a couple of drops of thick C/A. The location of the engine is not important at this time.

Page 22: Section 14: Fuel Tank Assembly & Installation
Step 3: Aligning and Installing the Engine Set the engine onto the engine mounting beams and temporarily install the spinner backplate onto the crankshaft. Using a ruler, measure the distance from the firewall to the back of the spinner backplate. Adjust the depth of the engine so the measurement is 4-1/8". - Page 23 Carefully bend the longer of the two aluminum tubes up at a 45º angle, being careful not to "kink" the tubing as you bend it. When the stopper assembly is installed in the fuel tank, the top of the vent tube (the tube you just bent) should rest just below the top of the tank.

Page 28: Section 18: Rudder Control System Installation
Install the control horn and backplate using two M2 x 12 machine screws, being careful not to overtighten them. Repeat the previous procedures to install the second control horn and backplate on the other elevator half. Thread the clevises onto the pushrod wires and snap them into the third hole out from the base of the control horns. - Page 29 Using a modeling knife, cut away and remove the covering material from over the rudder pushrod exit holes in each side of the fuselage. They are located 6" in front of the rudder hinge line and 3/4" above the bottom of the fuselage. Connect your radio system and plug the rudder servo into the receiver.

Locate two holes on each side of the cowling, 1/4" in front of the back edge of the cowling. One hole should be 1/2"...
- Page 33 Step 4: Aligning & Installing the Canopy Using a pair of scissors, carefully cut out the canopy along the molded scribe lines. Using 220 grit sandpaper with a sanding block, carefully sand the edges of the canopy smooth and straight. Be careful not to scratch the surface of the canopy when sanding its edges.

Page 35: Section 22: Lateral Balancing The Simply Magic 40
SECTION 23: CONTROL THROWS We recommend setting up the Simply Magic 40 using the control throws listed below. These control throws are suggested for initial test-flying because they will allow the airplane to fly smoother and make it easier to control. -
Page 36: Section 24: Preflight Check & Safety
SECTION 24: PREFLIGHT CHECK & SAFETY Completely charge the transmitter and receiver batteries before your first day of flying. Check every bolt and every glue joint in the airplane to ensure that everything is tight and well-bonded. This should include all of the control surface hinges as well. Double-check that you've installed and tightened all of the servo horn retaining screws. -
