3. head bolts in conjunction with 4 bonded sealing washers as shown 35 Install your switches battery and receiver as well as prop and spinner to achieve proper center of gravity Pipe or canister installation hints You may wish to install a tuned exhaust system in your aircraft We have built a pipe tunnel into the bottom of your aircraft to make this a relatively easy task Some of the advantages of using a tuned exhaust are an increase in power and a reduction in engine noise There are many makes of tuned exhaust systems available for 50cc engines For the DA 50 you will need to purchase a wrap around header with a 25mm drop which will position the pipe in the center of the tunnel You will also need to purchase a Teflon coupler and spring clamps Here are a few pictures of our installation of an ES Composites carbon fiber tuned www escomposites com pipe using a Dave Brown Products pipe mount Notice we have put a ring of high temperature silicon gasket maker around the pipe to prevent the melting of the nylon cable tie we are using to retain the tuned pipe 29 This completes the assembly of the 50cc Edge 540T As a final step clean the entire aircraft with glass cleaner then apply a coat of spray on wax and buff the finish to a high gloss with a micro fiber rag My favorite product for this is Eagle One Wet Wax AS U DRY available in the automotive section of most Wal Marts K marts Sears Targets etc People often ask me at
4. survived the journey half way around the world while experiencing several climate changes it is not uncommon for a few wrinkles to develop in the covering Fear not These are not manufacturing defects and are easily removed with a little bit of heat Use a 100 cotton tee shirt and your heat gun and heat the covering while gently rubbing the covering onto the wood with the t shirt Be careful not to use too much heat as the covering may shrink too much and begin to lift at the edges Take your time and a beautiful paint like finish is attainable 3 By the time your aircraft arrives at your door step it will have been handled by a lot of people Occasionally there are small dings or imperfections on some of the surfaces An effective method to restore these imperfections to original condition is to use a very fine tipped hypodermic needle to inject a drop of water under the covering material and into the ding in the wood Apply heat to the area with a sealing iron and the imperfection will disappear Deeper marks may require that this process be repeated a couple of times to achieve the desired result but you will be surprised at how well this technique works 4 DO NOT SKIMP ON SERVOS Your aircraft is equipped with very large control surfaces that deflect over 45 degrees A lot of servo power is required to prevent flutter and to maintain the required deflection for maneuvers We absolutely recommend the use of METAL GEARED servos with a minimum of

6. trade shows how I get the planes to look so shiny this is my method You may wish to apply all of your graphics before applying the coat of wax Set up and trimming Besides basic assembly this is the most important part of preparing your airplane for flight It can also be the most time consuming but once your plane is properly dialed in you will agree it was time well spent The center of gravity range for the 50cc Edge 540T begins at 6 25 inches from the leading edge of the wing measured at the root and extends back to 7 inches CG is determined with the EDGE in the upright position One of the best ways to dial in the proper CG for your aircraft is the 45 degree line test Fly the aircraft in front of you from left to right or right to left if you prefer at full throttle Pull the aircraft into a 45 degree up line and establish this line Roll the aircraft inverted neutralize the elevator and pay close attention to what the plane does Ideally the plane will continue on this line for several hundred feet before it starts to slowly level off If the airplane immediately drops the nose and dives toward the ground it is nose heavy If it begins to climb inverted toward the gear it is tail heavy There is no need to have the Edge excessively tail heavy to perform 3D maneuvers At this time you will also want to balance your plane laterally Add a small amount of weight to the light wingtip to achieve proper lateral balance 30 Control surface
7. 250 oz in of torque 5 Use a high quality epoxy for installing the composite control horns and hinges We highly recommend the use of Pacer Z Poxy 30 minute formula We have used this glue for many years with zero failures Recently we have been experimenting with Pacer Hinge Glue and are very pleased with the results and ease of application and clean up 6 You may want to add a bead of silicone glue Pacer Zap A DAP A GOO etc or RC 56 Canopy glue to the intersection of the plastic canopy hatch and its wood frame for additional strength and resistance to vibration DO NOT USE CA here as it will fog the canopy 7 Your aircraft is built using very modern construction techniques and is very light weight for its size As with any high performance machine regular inspection and maintenance is a must While disassembling your aircraft after a flying session pay close attention and inspect glue joints linkages and loose covering to be sure the airframe is sound A few minutes spent doing this will help maintain airframe longevity 8 Be sure to put a drop of blue Loctite thread locker on every bolt on this aircraft Failure to do so may cost you your aircraft Congratulations on your purchase of the Extreme Flight RC 50cc Edge 540T ARF The Extreme Flight Edge 540T is loaded with unique features including first rate hardware and components and thorough instructions to ensure a trouble free assembly and set up Weight saving components are used t
