About this Blog

This is about the combination of two interests, Radio Control vehicles and Science Fiction models. Its also about vehicle design. The models have to satisfy two main precepts.

1. The vehicles have to work, ie be driveable, but not nescessarily win any races or rock crawling competitions.

2. The main thing is that they have to look cool.

Escape Pod part 6

I completed scribing panel lines over the plainer areas of the surface and then finished up with spot putty and more grey primer.
I was trying for  a 1970's Science fiction book cover style and originally painted it yellow with some sections black and what from the cap colour looked like red but was really a reddish orange. Unfortunately the current fashion in automotive paints is more towards a lemon yellow rather than the warm orangy yellow I was trying to find so I relented and sprayed the warmest yellow I could find but it really wasn't working. I attempted to reduce the yellow down to stripes but it still looked like a dog's breakfast. After much more tedious masking I eventually sprayed over all the remaining yellow with the left over orange from the Toybash Truck project for the final result shown.
 My usual technique of weathering was applied and paint chipped off the edges of the panels by scraping with a scalpel.
Some decals from kit part nurny donors was added.




Below is a close up of the photo-voltaic panels. These were sprayed a blue metallic colour and then with a tiny brush different shades of  a blue, metallic turquoise and a black permanent marker were employed to pick out random squares. The permanent marker shines in an interesting pearlescent manner when it catches the specular light.












I still want to add some markings on the side and I'm thinking of adding some landing pads underneath. The pilots also need painting , however my holidays are over and its back to work on Monday so the pace of progress will regrettably slow.

Escape Pod part 5

After a slight deviation into the Escape Pod Mk2 project I returned to completing the cockpit of this Escape Pod project or Shuttle Pod as it has become.
I made up a seat assembly which is removable at the moment so that I can get some paint into the interior.


I decided to light the internals of this cockpit with bright blue leds, 4 in total and with a forward drop of 3 volts each all 4 could be wired in series and run on a 12 volt supply without a preliminary in series resistor.

I then made a console that fits over the light housing in much the same way as the Escape Pod Mk2 project using sandpaper frosted acrylic sheet diffusers surfaced with 1mm black styrene fascias perforated with screens and holes for lights. In this instance, due to the blue leds, there was no point using any Tamiya clear colours to back the various switches as they would only come out as darker shade of blue. I thought the blue-lit interior might make an interesting complimentary colour contrast with the hull which I am planning to paint yellow. We'll see if this works out in practice. The console has been nurnied using many tiny parts from a Trumpeter Stryker kit. If you want lots of really tiny nurnies that's the kit for you.






Next up is scribing panel lines and paint.

Escape Pod Mk2 part 1

In the middle of the Escape Pod project I did a trip to the local charity shops and came away with another dustbuster this time a different brand and shape and made of lovely ABS. I do not ever bother attempting to use any shapes made with HDPE ( high density polyethylene) or polypropylene as they cannot be reliably glued, sanded, filled or painted and to attempt to do so is going to be wasted effort.
I was thinking the first escape pod was a bit oversize and was more aptly described by a member of the RPF forum as a shuttle pod, so I thought this dustbuster could make a one person pod more in keeping with the original intent.


One of the other charity shop finds was a massive pink Barbie Jet Plane (which will become a future project) from which I salvaged the blue engine mouldings which I shortened by removing a section from the middle. The engines are fitted together with a box structure of 2mm styrene at an angle which matches the angle of the lower side of the dustbuster shell which has been gutted of its internals.





Slabs of 10mm and 6mm grey pvc make up the support rod housing underneath and at the rear. A hole was threaded 3/8 whitworth to match the 3/8 whitworth bolt I use as a support rod. Wiring for the engine lights and the cockpit lights is also installed and hooked up to a couple of 12volt DC connectors. The PVC is glued with thick super glue to heavily roughened surfaces.



Some kit part detailing of the back of the engine structure was done.


With all the wiring tested the two halves could be permanently brought together with the aid of the original screws, and the engine assembly glued on with the usual Methylene chloride solvent. The bottom panel of the engine bay was made removable and detailed. You can see the round bottom DC connector next to the support rod access which uses a rectangular hole that already existed in the housing.


Below you can make out the rear DC connector on the right hand side. It should be inconspicuous in amongst the rest of the nurnies.


An oval shaped cockpit window was added. The acrylic sheet clear material was softened with a heat gun and pressed with a cloth pad into the back of the dust compartment access door so that it took on the compound curvature before the hole was cut. It was then glued into position with solvent and masked up both sides. I'm using scotch brand fine edge masking tape here which does as it says, it works very well.
I have also added some fins at the rear. I was toying with some wings of some sort but decided it made it like too "aircraft" like which is not what I want.



The cockpit has had some minimal details added and a chair constructed. I also made up a dashboard which is lit by two bright white leds shining through some roughly sanded acrylic sheet to diffuse the light a bit. The leds have a 470 ohm resistor wired in series calculated for the 12 volt supply. The front surface of the dash has a piece of black 1mm styrene with a screen shape and 1.5mm holes drilled into it to stand in as switches and indicator lights. The back of the frosted acrylic has then been painted with varying hues of Tamiya clear colours to give the multicoloured lights effect. Its crude but should be enough when seen through the cockpit window. The light from the screen lights the pilot.



I had a search in my local Bunnings hardware store for something suitable for the engine lights and came across these 12 volt HPM brand led garden bulbs. They are designed for multiple fixtures and come apart to be adapted for what ever housing required. They were perfect for what I needed and come with a suitable bell shaped nozzle, I just removed the end lens and the internal reflector which just all press fits together. They also have the standard bi pin connector so I added a couple of the ceramic connectors I have in stock to the rear of the engines and plugged in the lights.






 Next up is paneling the hull and a final detailing pass but before that I am going to complete the first escape pod project.

Escape Pod part 4

Primer is on.
It didn't take too long to dry as it was 36 degrees Celsius here in the south west of Western Australia today. The primer overspray dried as it fell. Went around with a scotch brite pad to knock of all the furry bits of primer.
I decided to chip a couple of the black 1mm styrene panels off the top at the rear as I didn't like them.
I forgot to replace the hole plugs when I took the photos.









  I will scribe some panel lines into the plainer surfaces.

Escape Pod part 3

Most of the outer surface detailing has now been done. The black  bits are 1mm styrene sheet. There is still a few areas that may need a few bits added but I will spray a primer grey pass next to see where it's at before deciding.





I also finished up the retaining system for both hatches. The rear hatch has a plug that fills the hole for the support rod. The hole for the support rod also acts as the handle to pull the hatch up and forward to release. A couple of small round magnetic cabinet catches hold the hatch in place in each front corner. The steel washers from the catches are superglued to the under side of the hatch. You first have to roughen up the glued side with very coarse sandpaper so that the superglue can grip effectively, as well as allowing some to squeeze up through the counter sunk  screw hole. A squirt of accelerator helps the super glue to harden quickly.





The rear of the hatch is gripped by a long strip of plastic that hooks under the hull opening.


After stating on the RPF forum I wasn't going to hinge the canopy hatch, I went out and purchased a couple of tiny hinges and... hinged the hatch. The hinges are superglued to the hatch and to the hull again roughening up the glued surface, and in addition with a couple of m2 cap screws screwed in as part of the detail. The front is held in place just by the friction fit of the acrylic window into the hole in the hull. Some more positive closure may be required, we will see.





Next up is masking the windows, a grey primer pass and then starting the cockpit interior.
