Champion 7EC - User Manual

Fabric is attached to control surfaces using PK screws, washers, and pinked tape as described on the wing surface covering.

Rudder has a top leading edge for counterbalance. An adjustable trim tab compensates for yaw.

Elevators attach to horizontal stabilizers. Left elevator has an all-metal trim tab assembly operated from the cabin.

Designed in two interchangeable sections, with SAE 2330 steel rod braces for rigidity.

Integral part of fuselage, offset 7/8 inch to the left to compensate for torque.

All-metal, single spar, fabric-covered frames attached with clevis fittings for control movement.

Two types of fuel systems: 13-gallon fuselage tank with optional auxiliary wing tanks, or two 13-gallon wing tanks.

Main tank attached to fuselage top front frame. Auxiliary tanks outboard of wing butt rib.

13-gallon aluminum main tank in each wing, connected via manifold to firewall and gascolator.

Strains fuel, collecting sediment and water. Located on engine side of firewall.

Three slow primer pump movements force fuel into induction system for cold weather starting.

Main wing tanks interconnected by vent system. Auxiliary tanks have individual vent lines.

All control surfaces are cable operated. Steel torque tube connects control sticks for coordinated longitudinal control.

Rigging load 22-28 pounds. Adjustable via turnbuckles accessed through cabin enclosure.

Rudder tension is spring-loaded. No adjustment necessary. Nose gear steering integral with rudder on tricycle model.

Adjustable via turnbuckles aft of rear stick. Rigging load should be 45-55 pounds.

Access to friction knob via cabin opening. Tightening/loosening knob applies friction to tab adjustment arm.

Nose gear steering is integral with the rudder system on the tricycle model.

Details cabin enclosure components except pedals and control system parts.

Plexiglass used for minimal discoloration. Front left windows are aluminum reinforced.

One-piece stamped, spotwelded aluminum alloy door with integrated map compartment.

Recessed panel houses ignition switch, carburetor heater control, and fuel shut-off valve.

Floorboards consist of three-ply laminated fir, sectioned and bolted to the fuselage frame.

Equipped with exclusive 'No Bounce' hydraulic spring type main landing gear for minimum fuselage loading.

Incorporates frame and cylinder housing spring and hydraulic unit. Attaches to fuselage at specific stations.

Consists of spring, piston, cylinder. Requires specific oil quantity. Packing replacement instructions provided.

Welded non-heat treated 4130 steel tubing, attached to fuselage yoke and oleo assembly.

Cleveland C7000 Brake, internal expander, shoe-type unit. Hardened steel cams operate shoes.

Die cast aluminum alloy wheels, clamped with alloy steel bolts. Heavy gauge pressed steel brake drum.

Cleveland C2000-H Brake, internal expander, shoe-type unit. Hydraulic cylinders actuate shoes.

Cleveland wheel assembly C38500-HA used. Wheel halves similar to mechanical brake wheel.

SCOTT MODEL 3000-Al steerable or 3-24B full swivel assemblies attached to leaf spring.

Manganese Silicon steel fork with bronze bushing at bracket. Bracket and axle have Zerk fittings.

Provided to lessen strain in turning and absorb shock from rudder arm to tailwheel fork.

Attached to tail post bottom lug with bolts and shimmed with leather pads.

General solid rubber 6 x 2 steel wire reinforced tire to eliminate rolling off during rough usage.

600 x 6, 4-ply, low-pressure tires. Inflate to 15-20 psi depending on load.

A 500 x 5 tire used on the nose gear. Inflate to approximately 15 psi.

DO tie ship down, cover pitot tube, check fuel/oil, keep ship clean, check flags, oil pressure, controls, and sediment bulb daily.

DO fasten safety belt, check engine/mount bolts every 20 hours, lubricate oleos every 25 hours, face wind during warm-up.

DON'T use rudder edge to push, leave plane untied, hangar without fuel, use strong soap, imitate stunt pilots.

DON'T neglect 20/100 hour checks, neglect tire pressures (15-20 psi), or use waste fabric for cleaning windows.
