Congratulations on your purchase of the Extreme Flight RC 85" Slick 580 ARF! Purpose built for the multitude of 50-60cc engines on the market, this brand new airframe is the perfect complement to these venerable power plants that have been neglected for far too long. Our design team started with a very specific goal with careful consideration of weight, wing area and performance parameters to make sure we delivered the ultimate light weight 50cc performance machine.

A few tips to ensure success 1. We are very pleased with the level of craftsmanship displayed by the builders in our factory. Through hundreds of grueling test flights containing maneuvers that no aircraft should be subjected to, our prototypes have remained rigid and completely airworthy. Having said that, it is impossible for us to inspect every glue joint in the aircraft.

Since the 85" Slick 580 (and most of our other giant scale models) now come pre-hinged and the hinge gaps sealed, the most time consuming task of the assembly process has been eliminated. This leaves a very minimal amount of gluing for the assembler, which consists of installing the composite control horns in the ailerons, elevators and rudder, with only the rudder hinges needing to be glued.
Page 6
3. Scuff the portion of the horns that will be inserted into the elevator with sandpaper. 4. Locate your epoxy, mixing cup, an old pushrod to stir with and a length of nylon cable tie or cofee stirring stick to apply the epoxy. We have used Pacer 30 minute Z-poxy for over 2 decades with excellent results and zero bond failures and we highly recommend this product.

5. Mix a generous batch of epoxy being careful to use equal parts resin and hardener. 6. Use the stirring stick or cable tie to apply epoxy to the slots and thoroughly coat the control horns on both sides of each horn.
Page 8
7. Insert the control horns into the slots and ensure that the horns are properly seated against the base plate and the base plate is flush against the control surface. 8. Wipe away the excess epoxy with a paper towel soaked in denatured alcohol, making sure to do a good job of cleaning the area.

9. Repeat this process for the other stab half, the aileron control horns and the rudder control horns. ***PLEASE NOTE*** pull-pull rudder actuation with the rudder servo mounted in the rudder tray under the canopy is recommended for lightweight 50cc engines in order to achieve proper balance. If using a heavier 60cc or electric motor setup with large 12S LiPo batteries the rudder servo may be mounted in the rear of the fuselage.

(secure with heat shrink tubing or an EF Servo Safety Clip) and install the elevator and aileron servos in their designated locations. We highly recommend using the Extreme Flight socket head servo screws to mount your servos. The servo output spline of the elevator and aileron servos should be oriented toward the front of the model.
Fuselage Assembly 12. We’ll begin by installing the landing gear. Locate the carbon fiber main landing gear, 4-4mm bolts, lock nuts and washers. Insert the gear into the slot on the bottom of the fuselage and center it in the slot. Secure the landing gear with 4 4mm bolts, washers and nylon insert lock nuts by inserting the bolts and washers through the carbon gear and the aluminum gear mounts inside the fuselage.
Page 13
13. The landing gear fairings add a nice scale touch to the aircraft. Slide the fairing onto the gear and up against the fuselage. Secure the fairing to the gear with "Goop" silicon glue. Use blue painters tape to secure the fairings until the adhesive sets. 14.

Use your rotary tool and a grinding bit or a file to create a flat spot on the axle for the wheel collar and wheel pant support set screws to seat against. Attach the aluminum axle support to the plywood spacer with the provided wood screws.
Page 15
17. Slide the wheel pants into position and secure with 2 3mm bolts and washers inserted through the carbon gear and into the blind nuts in the wheel pants. Be sure to use thread lock on the bolts! Pull the pant back from the plywood support block and run a bead of Epoxy on the plywood surface to adhere the block to the wheel pant wall.

18. Next let’s install the rudder onto the fuselage. Glue the hinges into the rudder first with epoxy and allow to cure. Use a pushrod to apply epoxy to the holes in the rudder post and push the rudder into position and wipe away any excess epoxy with a paper towel and denatured alcohol.
Page 17
19. Drill a hole in the bottom of the rudder 3 inches back from the front of the bevel to accept the ball link for the tiller arm. Secure the ball link with epoxy. When dry slide the tiller arm into the hole in the ball link and secure the tailwheel assembly to the fuse with the provided 3mm bolts.

21. The distance from the front face of the motor box to the motor drive washer is approximately 172mm or 6.8 inches (this is the length of the DLE-61, the longest of the engines recommended). Because the DA-50 is the recommended motor we have included a set of machined aluminum standoffs to be used in conjunction with the stock 2.5"...
Page 20
These photos show the installed location of a KS 86 rear exit canister muffler. For clarity, we have only removed the covering over the outlet hole in the fuselage. There are many other small cooling outlets cut into the bottom of the fuselage, and the covering should also be removed from all of these.
Page 21
23. There is a hole in the bottom of the motorbox to mount your throttle servo. This location corresponds to the throttle arm on most single cylinder engines provides a straight shot from the servo arm to the throttle arm. Your kit includes a throttle pushrod assembly which will work for most engines. It consists of a pushrod with one threaded end, a ball link, and an adjustable pushrod connector.
Page 23
Note that your kit includes the wood pieces shown. This assembles into a servo mount. This is used if you must mount your throttle servo in an alternate location, or to mount a choke servo if desired. Additionally, if you use a canister muffler or tuned pipe, the throttle servo may hang too low in the stock location and be too close to the header pipe.
Page 24
24. If using an electric power system, we recommend mounting the ESC to the bottom of the motor box as shown. This is a sturdy, high-airflow area.
Page 25
25. If using a lightweight 50cc engine like the DA-50, mount your rudder servo in the servo tray under the canopy using the manufacturer supplied mounting hardware. For proper geometry use the Extreme Flight 3” pull-pull rudder arm with the cables crossed. Assemble the pull-pull cable linkage as shown by inserting the end of the pull-pull cable into one of the aluminum crimp tubes.
Page 26
If using a 60cc engine or large electric motor with high capacity LiPo batteries mount the rudder servo in the provided location in the rear of the fuselage with the output spline mounted toward the front of the aircraft. You will need to mount your rudder linkage to the interior side of the servo arm for sufficient clearance as shown.
Page 27
27. The elevators of the Slick 580 each require a 48" servo extension. Secure the extension to the elevator servo lead with an EF Servo Safety Clip or heat shrink tubing. 28. The 85" Slick features a spring-loaded lever on a carriage system that makes for a quick and sturdy stab mount.
Page 28
29. If using a 50-60cc gas engine install a Flowmaster 17 ounce tank onto the tank tray and plumb with EF Flowmaster Blue Fuel Line. There is a laser cut opening to accept an EF Fuel Dot as well. 30. Mount your ignition to the side of the motor box and secure with velcro, it is recommended to install some vibration-isolating foam between the ignition and motor box.
Page 29
31. There is a set of clear plastic baffles included to be used for electric setups to direct air over the motor. Cut and trim the baffles and glue to the cowl inlets with Goop or medium CA. 32. Secure the cowl to the fuselage by inserting two 3mm bolts through the sides of the cowl and into the blind nuts in the fuselage tabs along with 2 3mm bolts inserted through the F1 former and into the blind nuts in the cowl.
Page 30
33. Install your choice of prop (if using the DA-50 we highly recommend the Falcon 23x8 Carbon Fiber prop) and Extreme Flight 4" carbon fiber spinner. We have spinners available that are painted to match these color schemes. 34. Install your switches (there are suggested switch mounting locations laser scribed in the fuselage sides visible from the interior of the fuselage), batteries and receiver.
Page 31
36. Included with your Slick are a set of Side Force Generators (SFGs) along with 2 clear spacers to be installed between the SFGs and wing tip to prevent them from interfering with aileron movement. They are to be installed using the supplied white thumb screws threaded through the holes in the SFG, through the clear spacer and into the pre-installed blind nuts in the wing tip.
