Worlds largest RC Model ARFF

 You can see from the images that a massive amount of detail work has now been done on the Fire Truck. A few thing when tested did not work as expected so have been redesigned. All the nozel system have been changed and now work much better. The top nozel will be for a water/foam mix and the lower water only. The wheel nozels will also only sray water. The interior has been worked on with all the detailing added. The 4WD system was tested but there where problems with the belt drive so a tensioner was added which solved the problem. Fixing the belt ogether into a loop was problematic but time will tell if the solution works. New bigger speakers have been added firing downwards mid vehicle giving the engine sound more 'weight/volume'. A 5.8ghz camera system as also been added which will give a drivers eye view when running. I have decided to fit the yellow stripe but I am not sure about the tone of the yellow. I might replace this with a much more Neon yellow stripe. My fireman has also got a new fireman outfit rather than his military look. 

So what is the next step.

1. Register the build for a world record( worlds largest RC Model ARFF.

2. Program the radio system making the vehicle easier to use.

3. Get the yellow pinstripe sorted out.

4. Tidy up the rest of the electrical system.

5. Silicon and water proof the cab.

6. Second test of the water system playing around with the foam mix

7. Can it put a fire out test.

Now for the real work

 This is now the most dificult part of any build, making the thing that I am building look real. It requires hours and hours of work getting all the details just right. Still lots of weeks to go before we even get to the testing stages for the water systems, lights and sirens., but where would the fun be if it was completed in just a few weeks.

Working here of the detailing around the cab glass.

Top rails are staring to take shape

The basic shape of the top water canon is now complete and the two servos controlling it mounted and working.

Lots of LED lighting going on including the top flashing lights.

Working out where I will fit the main breaker.

Lots of details added, rear bumber, rear LED strobes and cooling fans

Decided to give it a number 5, first of the many decals which will eventually be added.

Front LED's and strobes mounted plus rubber bumpers. The low spray system has also been built and added but not fully tested yet.

Low spray nozel, all fitted and working with pan and tilt servos.

Overall the build is starting to come together. I decided to go with gun metal grey for the doors and am please I did. The darker grey does not look as good as this although once all the paint work and details are on it will all need weathering.
