1/50 Heller AS350 Ecuriel (Squirrel)

Some years ago a mate of mine picked up a few of these Heller water-bomber kits and on-sold them to a few other members of the Australian Defence Force Helicopter School, including me. 

The kit contained a few items that were needed for the Australian Army, Royal Australian Navy (RAN) or Royal Australian Air Force (RAAF) aircraft. Useful items included the high skids and hoist.

 The interior was detailed with belts for all seats, the pilots’ seats modified to high-back items with different cushions, a control pendant for the hoist, intercom leads and controls, new Honeywell panel (centre console), fire extinguisher and map case. The landing light area was also blanked off.
The fuselage rear section was modified with an extra access hole on each side of the transmission cowls, holes for the bleed air exhaust and accessory drive module magnetic plugs. Holes were drilled at the rear of the engine cowl and fishing line fitted to represent the sand filter exhausts. A new short tail rotor drive shaft cowl was scatch-built, the hoist hole relocated to the correct position and holes drilled for the HF long wire. The anti-collision light was removed and a new base for the strobe light made up from plasticard. A base for the lower strobe light and the Doppler antenna were made up from brass sheet. A UHF homing antenna was made up from wire, fishing line and PVA glue and fitted to the nose. Steps were also made from brass sheet and fitted to the skids, as was the vibration absorber on each skid.

The rotor head supplied with the kit was woefully inadequate, so a new one was scratch-built using the kit parts for some bits (it helps being able to check against the subject aircraft every day!). The main rotor gearbox received a set of torque links, too.
 The tail rotor was modified and received a set of pitch change links. The vertical stabiliser was filed down and the lower surface had a fence installed. The tail skid also needed reducing in thickness. A DMEA (boomerang) antenna was made, along with a pair of radio altimeter antennae and these were fitted to the lower tailboom, a UHF antenna for the roof was also made and fitted. The VHF/UHF antenna from the kit was also fitted to the tailboom.

The aircraft was painted using Testors Blue enamel and Humbrol Gloss White. This was a mistake as the gloss paints ended up way too thick, although the bright orange plastic didn’t help here! The main and tail rotors were painted in grey enamel with the blades painted using the actual Aerospatiale paint used on the aircraft. Colour bands were added to the main rotor components (these aid maintenance during rotor assembly and balancing).

A cargo hook was made up from plastic sprue and brass sheet, with fishing line making up the control loom and manual release cable. Fishing line was used for the HF long wire, with wire used for its bracing wires. Wipers were made and fitted, as was the temperature probe on the windscreen.

Decals were made up from Letraset and the unit graphic artist and copied onto decal sheet. The roundels and fin flash came from the Roodecals RAAF general sheet. 

Overall, a lot of work but in the end, worth the effort.
