Making the Pocher Aventador rear end easily removable

[roymattblack]

There are a lot of Pocher Aventador builders here and probably like me, most of you are seriously dismayed that all of your amazing extra detail work at the engine end is hidden once the car is complete, due to the all-enveloping rear end.

I'm working out a fairly simple way of making the rear end completely and easily removable without altering the look of the final model.

I'll post pictures of what I've done as they progress but so far, my rear end just lifts off in seconds, revealing everything inside.
When in place, it stays put and fits just as the kit should.
Taking it off and putting it back involves no fiddling about, wiggling or forcing.
The rear body just drops on, and lifts off.

sounds like a great mod, looking forward to the pics.

POCHER 1/8 LAMBORGHINI AVENTADOR
Making the rear end removable


The Pocher Lamborghini Aventador is a superb model that is only really let down by a few things.

There could have been a lot more engine/transmission detail included in the kit, but this is easily remedied by the determined modeller.
However, no matter how much more detail you add, 90% of it will be forever hidden by the all-enveloping rear end.
OK, the engine cover opens but that still only shows a fragment of the goodies hidden beneath.
If the kit is built ‘out of the box’, then the vast majority of the engine, transmission and rear suspension hardly even needs fitting. It is impossible to see, so why bother?

The logical alternative is to make the entire rear of the car from the doors back, easily removable.
Not as difficult as it might at first seem.
Fortunately the Aventador kit is built in stages and the rear body is one of them.

The instructions tell us to build up the whole rear section and then screw it forever to the main car assembly.
Why?

With a bit of forethought and careful (and simple) modifications the rear end can be dropped into place and easily lifted off to show the wonders beneath.
Here’s how…..

First:
Build up the whole rear end as per the instructions.
The rear is a large and hefty assembly that easily supports its own weight without distorting. This is a major plus.

Next:
Fix the side body panels to the rear of the door openings, but do NOT fix them to the upper rear body as per the instructions at any time.

Cut off the upper rear body mounting points from the upper back end of the chassis frame.
These interfere with the cooling ducts mounted inside the rear lower body on each side.

Trim the cooling ducts to a shorter, less ‘flared’ shape at the inner ends.
This will help clearing the chassis frame later on.

The front upper air intakes need trimming shorter.
This is one aspect that will look ‘different’ to the real car but with care, the trimmed off parts can be fixed to the upper underside of the roof behind the doors so the result is hardly noticeable.

Omit the etched mesh grille from the inside ends of the aforementioned vents.
These interfere with the fitting of the rear body and are not visible anyway.

Trim off the tiny ‘lip’ from the upper front edge of the vent panels on each side of the rear body.
These lips are meant to tuck under the roof but are completely irrelevant and only cause fouling issues with the rear body.

If all the above is followed, the entire rear body will now drop into place over the engine.

First, lower the front end into place, under the roof.
Keep the rear end as low as possible whilst doing this.
Once the front end of the rear section is in place, the back end just drops down over the rear of the car.
Done.

Now, in a matter of seconds, you can just lift the whole back end of the car off to show your admiring audience the superb engine and rear mechanicals of the car.
A few seconds later, and you have put it back.

Roy.

This is a really interesting idea. I've just build a HK-103 roadster bone stock and was certainly frustrated that all that beautiful engine work will go unseen. I'm thinking of building another copy (a coupe) and am interesting in applying your mods, but I am unclear on a couple of points.


Fix the side body panels to the rear of the door openings, but do NOT fix them to the upper rear body as per the instructions at any time.
I assume the screws you are telling us NOT to install are the two screws E in Step 25 (page 27) that go up through the mounting tabs which we've now cut off. But when you say to fix the side body panels to the rear of the door openings, are you saying to install screws N and B from Step 25 (page 28)? If so, I don't see how the rear body could be removed. If this is not what you are referring to, then what are you referring to?


The front upper air intakes need trimming shorter.
This is one aspect that will look ‘different’ to the real car but with care, the trimmed off parts can be fixed to the upper underside of the roof behind the doors so the result is hardly noticeable.
I'm not clear on this one. Your photo has an arrow which says "cut the end of the vent shorter", but how much shorter and where do I make the cut? Are you saying that I need to save the scrap piece and then attach it somewhere else?

Finally, your final photo shows your modified car, but I note that neither the wheels wells, the base plate, or the main air intakes are attached. Will the rear body still be removable with these in place?

The side body panels should be fixed in place as per the kit instructions, but do not attach them in any way to the 'removable' rear bodywork.

The vent sections only need trimming a small amount to allow the rear section to be dropped in place.
The rear 'upper' part of the remaining grey plastic part is 12mm long on my model.
If you want to be really fussy, the cut off part could be superglued to the underside of the car roof to line up with the removable bit.

All of the wheel wells, floor, air intakes etc remain untouched and don't affect the body removal.

I'll post some 'detail' pics shortly......
