ARF Build Review-Xtreme Composite 2.6m Edge 540

OK, lets get to mounting the ignition module and the battery for the ignition. Note that the placement of these components can vary due to balancing requirements. I've mounted the ignition and the battery on the outside of the fuse temporarily for the purpose of determining the location of the straps that will secure these components. After proper location was established, I moved the battery and ignition module inside the fuse and secured them there. This really needs to be done to ensure proper cooling of the engine with no obstructions of the exit air. Two pieces of red plastic wire molding were used to cover the spark plug leads to prevent chafing of the wires where they exit the fuse. Install the mufflers but do not locktite the bolts yet. Get a piece of card stock and tape it to the fuse just aft of the cowling indentations on the fuse. Lay the card stock over the mufflers and mark out where the cut outs should be for the muffler penetrations through the cowling. Remove the mufflers and reattach the cowling and transfer your cut out marks to the cowling underside. Add about an inch more to the length each way for the first initial trial fit from the actual diameter of the mufflers. Cut out the areas necessary with your rotary tool. I like using the 1/4" sanding drum for this operation. It may take a few times trial fitting the cowling to establish the final size of cut outs. When cutting is finished, sand the inside of cut outs with some 200 grit sand paper for a smooth appearance .
When the muffler and exit air cutouts are finished, fit the supplied baffle inside the cowling and secure it with your epoxy mix. This is a very important step and should not be omitted. It is imperative that proper air flow over the cylinder heads be maintained. When satisfied with the fit of the baffle, reattach the mufflers now using Red locktite on the bolts. Let's get to the rudder assemblies at this point. Install the rudder servos in the servo tray. I used Hitec HS 5955TG for my rudder servos. Fit the tail wheel that you intend to use. I used the model manufactured by Ohio Superstar for 35% aircraft. This is trial fit and will be removed and replaced after the rudder is installed.
Place a piece of painters tape over the cut out for rudder control horn on both sides of the rudder. Cut out the tape from the slot with your hobby knife and apply some Vaseline around the cut out. This will keep the epoxy off of the rudder when you glue in the control horn. Apply liberal amount of your epoxy mix to the control horn and inside the slot. Fit the control horn ensuring equidistant measurements to each side clevis attachment points and proper axial alignment to the rudder hinge pin. Push the control horn to the front of the rudder slot. This will set the control points slightly ahead of the hinge pin axis and ensure good geometry with the rudder servo extension arm that is slightly offset. When dried install the rudder using the hinge pin. Bend the hinge pin 90 degrees at the bottom and secure to the rudder using a piece of clear packing tape. Reinstall the tail wheel at this point. Establish your cut outs for the rudder control cabling using the dimensions in the above pix. The slot should be 2 3/4" long, 3 1/16 down from the centerline of the horizontal stab, and start at 9 3/4" from the end of the fuse, cutting forward to the canopy. These dimension work with a rectangular cabling set up. I used this method to ensure proper geometry instead of crossing the cables. Also, I think it helps to eliminate possible sources of RF interference that sometimes occurs when you cross the cables.
Attach your cabling using the supplied cable and clevises of your choice. The servo extension arms are a quite bit thinner than I would like, as I prefer to use 4-40 ball links on my connections. I used the supplied arms, clevises, and Air Wild cable connectors at the main rudder servo extension arm. Make sure that your cable cut outs on the fuse are correct and the rudder cabling does not touch the fuselage at any point of travel. Reattach the tail wheel with the springs provided by the manufacturer.
