gearbox – Shane's Shed

Hummer H1 Build Progress

First up in this section is the gearbox.

The brake disc and pads are added to the gearbox.

The pin at the top will be attached to the throttle servo later which will apply the brakes when the throttle is released.

The gearbox is added to the chassis connecting to the the front and rear drives.

I have also added the fuel tank which is simply held in with two screws.

These are not fully screwed in to make sure the fuel tank can rock slightly.

The electronics box is now added. This houses the battery box, steering servo and throttle servo.

The steering servo is connected to the steering rod.

Here you can see how the throttle servo also connects to the brake pin allowing it to both control the flow of fuel into the engine carb (when fitted) and the brakes.

Phoenix BX gear mesh fixed and ball-raced

Last time I was out with this buggy a gear stripped and I later found out the gears were not meshing properly. When my ball-race bearings arrived I took the car apart upgraded it and re-meshed the gears. Its now running at a decent pace and it great fun to drive!
