This is a Lego minifigure scale model of a Texas Air Tractor AT 802F which is a fire protection seaplane built over a standard Texas Air Tractor 802 frame. This MOC was created from the standard crop dusting version of AT 802 - the standard AT 802 crop duster was rebuilt so it could share a standard landing gear fitting with the Fire boss. This version differs from the real world plane in following ways:(1) the cockpit and (2) the pontoon/floats structural supports. Below is a real world photo of a Fire Boss.
I've tried to make the Lego model *swoopable* - that is - the Lego plane model can rapidly through the air without falling apart or becoming too heavy in the arm when playing with it.
I created this moc not just by looking at the drawings and technical data on the AT 802F but also by studying other attempts at making the AT 802F so I would like to thank all the other AFOL builders (especially for Zorko Huljic for submitted his AT 802F models to Lego Ideas) for sharing their works with me... my model does not have as much functionality or play value as I would like but its a start...
The functional elements are (1) spinning 5 blade propeller, (2) spinning pontoon landing gear wheels, (3)cockpit opens and closes and can fit one minfigure, and (4) adjustable pontoon rudders. In addition, Fire Boss *seaplane* options can be swapped out and replaced with regular crop duster landing gear. If you think something could be improved or is missing - leave a comment below and I will look into it. This model was originally began as a project for the Lego Air Command Group on Facebook.
