E Aristocrats remain flying and are highly valued by their owners and Waco enthusiasts alike. The SIG 1/6th scale Waco SRE ARF kit is a very nice tribute to the exquisite lines and high-performance capabilities of its full-scale counterpart. Based on the full-scale NC1252W SRE, the SIG Waco shares its beautiful color scheme and undeniably Waco lines.

ENGINE SELECTION: (7) standard servos. Also, we chose to replace the typical 500 – The SIG Waco SRE ARF model is designed to be powered by glow 600maH airborne NiCad battery pack for a larger after-market engines in the following types and size ranges: 1100maH pack.

Last, use a small piece of tape to at the other). Locate Bag #21 and remove four (4) Nylon Control identify the two servo leads as the aileron leads.

With the servos now moving in the adjust the clevises to neutralize the flaps at zero, or no-flap. Now correct directions and the output arms in place correctly, linkages test the flap movement with the transmitter.

As you did when mounting the flap horns, use a #57 (.043”) dia. bit to now drill two parallel and perpendicular into the aileron at the marks just made, about 3/8”...

Allow the glue to dry. 5) The elevators are now hinged to the horizontal stabilizer, using the hinging methods described earlier for the flaps and ailerons.

If it will not fit at the two rudder control horns. Use a piece of masking tape at the position, try reversing it on the output shaft.

NOT mount your engine on these motor mounts by drilling and tapping them for bolts or screws! These mounts should be drilled for clearance of the engine mounting bolts and the engine itself should be secured to the mount arms with bolts, washers and lock nuts.

3) The engine mounting bolt holes are now drilled through the then through the corresponding hole in the firewall. Engage the two mount arms. These four holes should be clearance holes for threads of the blind nut being held in place and begin threading it the bolts you intend to use.

Prepare the throttle servo by first installing the rubber grommets and eyelets into its mounting lugs.

Doing this now avoids any confusion later when connecting the fuel FUEL TANK INSTALLATION: lines to their proper locations on the fueling valve and/or engine. 1) The completed fuel tank is now installed into the nose of the model.

Our reason for using this part was to neatly and efficiently redirect the exhaust back to the stock muffler that we mounted into the c) Lay a ruler on the side of the fuselage, centered over the bottom center recessed opening at the nose of the fuselage.

This tube bends surprisingly well and will hold its these holes exactly in the center of the lite-ply and drill them both shape provided you over-bend it a little.

Note that in the case of the Saito cast As mentioned earlier, we chose to install an after-market glow aluminum muffler (described earlier), the small, machined ridge at driver system in our Waco models.

The SIG 4” Epoxy Spreader - #SIGSH678 - is perfect for this job. Remove any excess fluid with a dry paper towel and allow the decals to set overnight. They will be solidly adhered to the model without any air bubbles.

Repeat this process with the remaining seven turnbuckles, cables, and swages. You should now have eight turnbuckles with the flying wires attached and locked in place. 3) All eight turnbuckles, with the flying wires attached, are now mounted to the bottom surfaces of the two top wing panels, using eight of the provided T2.6 x 8 mm PWA screws.

8) The top fuselage access hatch can now be reinstalled in place using the two T2.6 x 8 mm PWA screws. If your cowl is not in place on the model, reinstall it now. 9) From the kit contents, locate Bag #16, the aluminum scale spinner.

Make it a routine part of your pre-flight procedures to check each If your transmitter uses a toggle type flap switch and you have control on the airplane, making sure each flight surface is moving set-up your flaps as suggested in this manual, then you should in the correct direction.
