Base vehicle: Batman Begins Batcopter
Seat and console: Coastal Defender
Cannon: Dragonfly side cannon.
This is one of the simpler customs that I have made. The canopy was cut open and the batman torso and floor it was attached to removed.
The floor opening had to be enlarged to accommodate the seat and console from the Coastal Defender. Most of the rubber parts were removed and the landing gear layout was altered to make space for a different front gun.
When I posted this on the board, people were commenting that my original choice for the front gun was too small and it did not flow with the rest of the vehicle. I exchanged the original barrel with the one from the Dragonfly side cannon and it did the trick.
All that was left to do was to add a blue color scheme and some stickers from the KB's CAT II.
