ARF Build Review-Xtreme Composite 2.6m Edge 540
Distributed by BVM Props Review by "Rockin' Rick" Part 2
Now we will begin construction of the fuel and smoke tank deck assembly. The kit is supplied with necessary parts to install one fuel tank, but I chose to install smoke on this model and thus it will be necessary to custom build a tank platform. Start by determining how far below the wing tube to place the platform. The distance will vary depending on what type of tanks you choose. We used the square tanks similar to those provided by B&B Specialties. Cut out four slotted brackets to receive your support brackets and epoxy them to both inner sides of the fuselage. Using some of the parts from the supplied tank deck parts plus one piece of 3/32 lite ply build your tank support brackets. Epoxy these into the slots that you've installed in the fuse. The lengths will vary depending how deep in the fuselage they are placed. The tank platform is built from another piece of 3/32 lite ply and and sizing will be determined by the tanks you use. I incorporated a small plywood extension on mine to mount the Sullivan smoke pump. Slot the holes for your tie wraps and check the deck for a good fit. If satisfied, remove the deck and reserve for installation later. I like my tank decks removable, so I used bolts with blind nuts under the deck on the mounting rails.
Next, we'll work on the horizontal stab and elevators. I guess I'm just one of the lucky ones who received the model without the slots for the servo extension arms or elevator control horns pre-cut from the factory. I got in touch with David Shulman at BVM and he promptly sent me the template at the above left to use as a guide in order to slot these myself. Start the assembly by fitting the stab and elevator together then inserting the hinge pin. When the hinge pin reaches full travel, make a 90 degree bend at the inside end of the elevator and secure the hinge pin to elevator inside edge with a piece of tape. Place a piece of painters tape over the places to be slotted and mark out the slot locations on the tape. Then use your rotary tool to cut out the slots. I don't like using cut off wheels for this step and prefer to use a 5/64 drill bit. It's easier for me to control when cutting composite materials. Be extremely careful not to cut the slot for the elevator control horn too deep. Mount the servo inside the stab and connect the servo extension arm. I used Hitec HS 5955TG servos for this application and had to trim the servo mounting plates a bit for proper fit of the servo. I found this to be necessary at all the servo mounts on the aircraft. The provided cut outs inside the stabs were too small to receive this particular servo properly. Trial fit the elevator control horn for proper alignment with the axis of the hinge pin and also match its top hole with the height of the top hole in the servo extension arm. Most likely, your have to trim some off the elevator control horn to achieve proper height and axis positioning. When you are satisfied with the proper position, epoxy the elevator control horn in place. Install the pushrods with the clevises. I found that the clevis pins mounting holes on the arms and horns were bored out too large for the supplied clevises, thus leaving quite a bit of slop and a lack of positive control. The elevator could wobble up to 5/32" . I corrected this inadequacy by using the clevises provided by Composite-ARF that are stronger and have a larger diameter clevis pin. Perform the positioning and alignment of the aluminum horizontal stab tube as per the provided instructions that came with your aircraft. I used a 3mm tap to thread the stab tube for the bolts and also used epoxy to hold the 3mm blind nuts inside the tube. Place a generous amount of Vaseline on your bolts and on the top of the blind nuts when performing this step. The bolts will be easily removed should some epoxy get on them. |
