These instructions are laid out along what we consider the most efficient/logical construction flow, your approach may differ

Parts that simply replace the kit parts

  • GE F110-129 engines
  • Vertical stabilators balancing weights/antennae
  • CFT pylons (Be careful removing the casting blocks, these parts are quite thin on the upper edge)

Upper fuselage antennae

First, cut the upper fuselage aft of the speed brake as shown below and insert the resin part with the large GPS antenna

MAWS tail booms

The existing booms must first be cut out. As the MAWS booms have a different profile than the original booms the lower part of the vertical stabilators will also need to be adjusted to match this profile.

  • The cuts should be done once the halves are glued together to ensure top/bottom alignement
  • Cut as close to a vertical plane as possible, and start by cutting about 1mm aft of the indicated panel lines so you have room to progressively file/cut excess material and achieve perfect fit
  • Once the tail booms are glued on, mask the surrounding areas, fill any gap with modelling putty and once dry remove any excess with nail varnish remover or diluted acetone

The GWH kit needs to be cut vertically along the side (outer) panel line

MAWS antennea on cockpit sides

The antennae should be fixed flush with the edge of the cockpit, their front edge 22.5mm aft of start of the main canopy slot

CFT pylons

The CFT elongated pylons replace the regular pylons

The hooks are provided with a spare or two just in case. Simply take them off the casting block, lightly sand the base and slide them in the dedicated pylon slots

Small CFT scoops

Cockpit

The original front IP is too much backwards, leading to a too long IP coaming. To correct this it is required to fill the existing slots and mount the pilot IP directly on the front end of the cockpit sill
