It was noted on the Lead Adventures Forum that the Airfix Quick Build models included a number that were approximately 1/56 scale and hence suitable for use with 28mm figures.
The models are scaled to fit the boxes, but the Harrier kit was stated by one of the contributors to be a suitable scale.
The box is bright and colourful.
The kit is designed for younger modellers and internally resembles Lego bricks. William Killian is present for scale. There is a set of self adhesive markings, including representation of the turbine.
It is very important that you follow the instructions closely, the parts have some easily overlooked interconnections. If you do not follow the instructions you will need to take parts apart and put them together in the correct order.
Unfortunately it does not come with an undercarriage, being designed to be mounted on a flying stand. As you can see, it is a a suitable size for 28mm figures.
I will either use a Crooked Dice Dare Sisters helmeted head, or one of theTime Lift Security jet pack heads.
Easy to put together if you follow the instructions and it looks like the real thing. Constructing the undercarriage will be the next thing (and filling in the odd gap between the parts).
