I replaced them with 2mmx5mm socket head screws. It was also necessary to remove the two canopy mounting arms from the frame as they interfered with the fuselage. Putting a piece of tape over the end of the boom insured the belt didn't disappear into the boom. I had to remove the entire tail block in order to install the boom into the fuselage. You will need (4) 2mmx5mm screws for attaching the brackets and (4) 2mmx12mm screws for attaching the servo. I then had to mark and drill the holes for the servo as well as where the new bracket attaches to the old one. I cut one side to fit the width of the servo and the other so as not to interfere with the existing top screw that holds the original bracket tight to the boom. I made these starting with a piece of 1-1/4" aluminum angle stock I found at the local hardware store. This required that I fabricate two angle brackets that attach to the existing brackets. Once this was done I set out to move the rudder servo so that it hung vertically below the boom. First I stripped off the two boom supports, tail push rod, push rod guides, horizontal fin and attachment block. The next step was to get the tail ready for installation into the fuselage. I also added a layer of dryer cloth (the sheet kind that you throw in with your clothes when they are drying to make them smell good) and epoxied over it as well. I chose to apply a coat of epoxy over the outside of these blocks to reinforce them. The riser blocks are made up of several pieces of plywood that has been laminated. I attached the supplied riser blocks to the bottom of the Trex Sport frame using the supplied four screws, which attach from the bottom of the blocks up into the frame. Next I turned my attention to fitting the mechanics. This is where the riser blocks will set and you want full contact between the block and floor, again to reduce vibration. Once all the epoxy joints have set, I sanded the top of the struts where the come up through the fuselage floor flush. By making sure the struts are firmly attached to the fuselage, you are reducing a possible cause of vibration. Then I applied epoxy around the struts where they went through the bottom of the fuselage. Once this had dried, I used painter's tape to mask off the bottom of the fuselage where the struts exit as seen in the next photo. Then I applied 5 minute epoxy to the area where the struts meet the floor. Once I had all the struts lined up I applied weight to the fuselage so that the struts were seated and the skid pipes sat flat on the ground. I installed the skid pipes to the four struts, then slide the struts into the underside of the fuselage and into the slots in the fuselage's plywood floor. The first step was to attach the landing gear struts to the fuselage. Check out the video below for an overview of this project. If you're thinking your going to just slide the Trex 450 Sport into this fuselage and fly, your going to be disappointed. The build was a little more involved than I originally expected but quite fun. I found the Align fuselage at Horizon Hobby and by using a 10% discount coupon they had sent me, I got a great deal. Below, I've documented the build with video, pictures and notes in hopes of passing on some helpful building tips. I just recently completed a scale project using Align's 500E fuselage and mechanics from the Trex 450 sport.
