RB7 Progress: Air Filter

helmet1

As I mentioned in my previous post. The air filter is something special on this model. It is in fact hidden within the drivers helmet.

I soaked the filter sponge in filter oil before screwing it into the helmet structure. Decals were then applied to the helmet to give it the detail shown in the photos.

Who would of though Mark Webbers head would become an air filter?

Red Bull 7 Progress

rbengineexhaustIn this session I have added the exhaust to the gx-21 engine for my RB7. Its immediately noticeable that the exhaust set-up is very different to on a standard nitro car.

It has a compact exhaust system that goes straight out of the back of the chassis rather then the common side pipe method. This adds to the scale realism because it means it will all be tucked away neatly under the body shell.

I have also added the receiver battery case and on/off switch at this stage.

Next up will be the air filter which may sound boring but this ones special.

Red Bull RB7 Progress

This section of build brings the engine closer to completion.

Here I have added the flywheel and clutch to the engine. The engine now has clutch bell with gear enabling it to mesh the the main gear on the chassis.

Below are some photos of what the engine will look like when its attached to the chassis.

In the next collection of parts I will get the exhaust and manifold, enabling me to fit the engine onto the chassis.

Hummer H1 Body Complete

IMAG0486

I have finished working on the body of the Hummer H1 model. There are a few spots to touch up with paint but aside from that it is complete.

On the front of the vehicle I have added the logos, windscreen wipers and lights above the windscreen.

IMAG0497

One of the most noticeable additions is that I have added the tinted window panels.

These really enhance the look of the model. Some of these panels will need to be removed however when running the car in order to provide adequate cooling for the engine.

IMAG0496

On the rear of the vehicle I have added the indicators, small rear lights, number plate and plug socket.

IMAG0491

The aerial, side indicators and Hummer logo have also been attached at this stage.

Adding the lights really enhanced the look of the model and I am very pleased with how they come out using clear red/orange paint.

Now all that is left for this model is the engine, exhaust and radio equipment.

 

Red Bull 7 Progress

IMAG0458In this section of the Red Bull  build I have almost finished building the engine, its nearly ready to be fitted to the chassis.

The final tyre has also been added to the car. This is great because I finally have all four wheels on the model but annoying because it has now out grown its old living space.

IMAG0464

With this 1:7 model and the 1:8 Hummer I am building its getting hard to find space to store these models.

Hummer H1 Build Progress

IMAG0108

First up in this section is the gearbox.

IMAG0109

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.

IMAG0111

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.

IMAG0295

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.

IMAG0298

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.
