The horizontal member is also cut to shape in the same way as are the delrin bearing blocks.

This picture shows the upper front delrin block in position. You can also see the flanged bearing in place, this is a standard component in the 3D Pro kit and is ideal for this instance.

This picture shows the RC-Helitech belt drive jockey unit bolted in place.

The unit is held in place at the front and at the rear by M2 nuts and bolts that pass through the horizontal plate, the jockey unit and the lower rear delrin support block.

This component supports the tail and therefore is connected well to the horizontal plate.

The main mast is produced from an outer tube of 8mm Alloy and an inner bearing support tube of 6mm alloy,

This image shows the components of the mainmast with the servo plate cut from carbon.

The components can now be glued together with JB Weld checking for square as work proceeds.

This stage is best done by assembling the entire chassis and fitting the maingear, this way the mainmast can be slid down within the top support block so that the bottom face of the lower mainmast bearing touches the top surface of the maingear to ensure the correct vertical free play.

The servo plate is locked in position by a small collar of 10mm dia alloy tube.

The chassis can now be assembled with the maingear in place.

This shot shows how the motor is underslung beneath the horizontal member.

The servoplate has a cut out in front to aid access to the motor mount screws.

The right sideframe has provision for the tail servo.

Below is the completed chassis
