The ACIES6400 is one of the first micro pusher jets to utilize the PZ6400 series of receivers. The model tracks very straight at all power levels when properly trimmed out. The ACIES airframe comes laser etched with the exact location for equipment. This etching takes the guess work out of equipment installation and aids it the proper balance of the model. The kit includes a pre-made and plugged battery extension for use of the 160mah series of batteries (this extension is NOT needed when using the 240mah pack). The model comes with a full color light weight decal sheet in the color of your choice.
