Flying Controls

The rear control column is detachable by removing two safety pins and withdrawing two pins at its base. The rudder pedals may be adjusted on the ground only to any of three positions, by adjusting the tube to which each pedal is secured and which is held on the rudder bar by a pin with a retaining spring clip.

Flying Controls Locking Gear

The flying controls locking gear consists of two rods which are fitted over the controls in the front cockpit. One hooked rod is fitted, the larger end over the left-hand end of the rudder bar and the smaller end on the red-coloured bobbin provided on the port side of the control column base. The clip on the other rod is fitted to the control column and tightened by means of a winged nut, while the two ends are secured in spring clips on the fuselage walls.

Flaps Control

A manually-operated flaps control lever is fitted on the starboard side of each cockpit. The flaps have three positions, UP, 15% FLAP and 30% FLAP. To move them down to the mid position or from the mid to the up position, a hand operated spring-loaded trigger fitted at the top of each lever must first be operated to release a pawl in the front cockpit quadrant. Each lever is provided with a guard to obviate accidental movement. The lever may, however, be moved from the up to the mid position or from the mid to the down position without operating the trigger. As the flaps are easily visible from both cockpits, no poisition indicator is fitted.



Trimming Tabs

An elevator trimming tab control marked UP-NOSE-DOWN is on the port side of each cockpit. The control is marked so that all positions forward of "neutral" are black and all positions aft of "neutral" are white. The trimmer tab setting is read off at the top of the trimmer wheel casing. The rudder and starboard aileron have fixed tabs.



Wheel Brakes

A manually operated brake lever, spring loaded in the aft position is on the port side of each cockpit. The brakes may be set at any position by pressing down on the collar on either lever, to engage a pawl on the quadrant. Slight backward movement of either lever releases the pawl so that the lever can be moved to the off position. The brakes should not be left in the fully on position when parking for long periods, as it may strain the system.

Electrical System

A 24-volt electrical system is installed, and an engine driven generator charges the aircraft batteries for the operation of the radio , the oil temperature gauges and the usual lighting services.



A master electrical switch marked GROUND and FLIGHT is fitted on the port side of the cockpit below the instrument panel and should be turned to FLIGHT before starting the engine. If it is left at GROUND, the electrical services will after the engine is started , be running direct from the generator, and should the throttle be closed for any reason during the flight, the services will fade out. The switch should be left at GROUND when the aircraft is parked.



An external battery socket is fitted on the port side of the fuselage for ground testing purposes. When an external battery is plugged in, the master electrical switch should be turned to GROUND



A generator power failure warning light is mounted in the top left-hand corner of the instrument panel in the front cockpit, and comes on when the generator is not working, if the master electrical switch is at FLIGHT



Vacuum System

An engine-driven vacuum pump is provided for working the gyro-operated flight instruments. A vacuum gauge is fitted to the lower left hand side of the front cockpit (see above photo), both if Mod H91 is embodied.

Fuel Tanks

Fuel is carried in two flexible 9 or 12 gallon tanks, mounted one in each wing, and is fed to the engine from both tanks simultaneously, non-return valves preventing the contents of one tank being transferred to the other. The valves also prevent the engine "cutting" if one tank is empty. Each tank is vented to atmosphere and has a ball valve which seals the vent when the aircraft is inverted.



Fuel Contents Gauges

A direct-reading fuel contents gauge is fitted in the top of each tank, next to the filler caps. The red figures indicate the contents when the aircraft is on the ground attitude and the white figures when the in the flying attitude. In flight the gauges can only be accurately read from the front cockpit.



Fuel Pumps & Priming

Two engine-driven fuel pumps are installed, and priming of the engine before starting is effected by two hand-priming levers on the fuel pumps, and by the carburettor flooder control.

The use of either of the hand-priming levers ensures that the fuel pumps, the pipeline to the carburettor and the carburettor float chamber are filled with fuel. The lever on the rear pump is fitted with an extension lever so that it may be reached and operated through an opening in the port side cowling panel.

The carburettor flooder control (located on the starboard side of the engine), which is operated by a pull wire through a second opening in the port side cowling panel, enables the carburettor to be flooded, and thus provides the required rich mixture for starting; this is done by operating the fuel pump lever whilst holding out the carburettor flooding device, with the fuel cock ON





Fuel Cocks

A fuel cock lever marked ON (fully forward) and OFF (fully back) is to the left of the base of the control column in each cockpit.



Oil System

The oil tank, situated forward of the bulkhead, has a capacity of 2 gallons of oil and 3/8th gallons air space. A dip-stick is embodied in the filler cap, which is under the engine starboard cowling. Oil temperature gauges and oil pressure gauges are fitted on the instrument panel in each cockpit.

Hello all,

While I hope this board gets plenty of use please be aware that there are also very good and informative resources at :

Chipfest Forum : Chipfest

Chipmunk Forum : Caledonian Chipmunks

Yahoo Group : Yahoo Group

And for those of you who don't just love Chipmunks (heaven forbid!!) : Flyer Forum

I had the pleasure of attending all 4 days of the Chipfest event with G-APLO, and would just like to thank Marshall's who could not have done more to make us feel welcome and put all their facillities at our disposal. I hope you dont mind but I thought I would post some of my pictures below, there not great but.......
