The 110” Muscle Bipe is a large aircraft and so we’ll begin assemble by installing the landing gear to get the aircraft up on the gear and make it easier to move and position. Locate the landing gear and attach the...

Locate the gear fairings and test fit to the gear to find proper orientation and make sure there is no interference. Glue the fairing to the landing gear, not the fuselage. This allows the fairing to move with the gear as it flexes. Use a large dollop of GOOP or similar rubberized adhesive to glue the fair- ing to the landing gear leg, tape in place and allow to dry fully.

Install the wheel axle into the carbon gear withthe flat spot pointing down at the runway. Assemble the wheel pant support as shown. Install the wheel, then the wheel collar, then the pant support as shown. Install the pant with two 3mm screws and loctite. Apply a dab of epoxy glue in-between the interior surface of the wheel pant and the wooden pad of the pant support, allow to dry.

Locate the tailwheel, screws, and tiller keepter (nylon ball link). Glue the keeper into the hole in the bottom of the rudder with epoxy. Install the tailwheel onto the fuse using the screws and blue loctite. Put the plane up on its landing gear. Apply epoxy to the hinge holes in the fin and install the rudder, feeding the tailwheel tiller wire into the keeper.

All the control horns on the aircraft install in the same way. Scuff the gluing surface of the horns using 80-240 grit sandpaper. Assemble the horns with their ball link as shown. Remove the covering over the slots under the cover plate as shown. Assemble the cover plate onto the horns and test fit without glue, make sure the horn slides all the way into the surface.

Servo installation: You MUST use a top-quality, high-performance metal-gear digital servo on every location on this aircraft. Pictured are the MKS HBL-3850. Other good choices include the Savox 2290 and JR8911. Failure to use adequate servos can result in flutter and the loss of your air- craft.

The upper wing center section is attached to the fuselage with four aluminum cabane struts. These struts attach to the fuse and the center section with screws and washers. USE LOCTITE on these screws! The wires for your upper wing aileron servos will follow the rear cabane struts up into the cen- ter section.

Drill the firewall as appropriate for your engine. The Desert Aircraft 80x90mm pattern is marked on the firewall. If using a DA-200, you will need the Blazing Star DA-170 mount from Extreme Flight. Use large washers and locking nuts on your engine mounting screws. If using the spacer syustem for twins, use loctite on all bolts.

For our installation of the DA200 engine, we used throttle and choke servos arranged as shown. We used the DA brand ignition kill switch to control the ignitions, and we used a single 50oz Flowmaster tank from Extreme Flight with a simple brass Y-connector to split the fuel flow to the twin carburetors.

For the installation of a DA170 or GP178 twin-cylinder engine, a box-style spacer is includ- ed with your kit. We recommend the use of red loctite or high-temp RTV sealant for thread- locking of these fasteners.

The 110” Muscle Bipe kit includes a top-to-bottom flow style baffle. Airflow is taken in on top of the engine, and passes through the cylinder head cooling fins to the bottom half of the cowling and is expelled out of a cooling hole at the bottom of the cowling. Pictured here is the DA200 installation using the 4-cyllinder horizontal baffle plate.

Shown here are the alternate horizontal plates to fit twin-cylinder engines and the uncut plate for other applications requiring a custom shape. When cutting or trimming on these plates for your installation, wear eye and lung protection, as the reinforcement is carbon fiber. The bottom photo shows the installation hardware for the baffles in-place.

The upper wings are attached to the lower wings through two interplane struts. Each wing receives an interplane strut mount. Dry-fit these mounts without glue and make sure the fit is good, then install with epoxy. The interplane struts mount for flight with wire pins pressed in to the strut and mount as shown.

With the DA200 engine installed, the 110” Muscle Bipe comes out slightly nose-heavy, and we enjoy its flight performance like this. Our prototypes with our setup balanced level hang- ing by the UPPER main wing tube. We placed our batteries (3x 2s 5000mah lipo) at the rear of the hatch under the cockpit and used no other ballast.
