Hi,

I am interested in buying an SPV kit  (captain scarlet spectrum persuit vehicle), to accompany my 1/72 scale  Airfix Angel Intercepter kit,however i want to at least try and keep them both to a somewhat near scale as each other.
I cannot find out what scale the IMAI SPV kit is,do any of you have any idea?
Or maybe be able to recommend a kit that is very close in scale to the Airfix Angel Intercepter kit.

Imai do an SPV kit that measures at about 7.5 inches in length,i have no idea what scale this would equate to,does anyone know how to work out the scale size from this,as i cannot find out how long the vehicle would ber if it were real.

Any help with this delema would be helpful to me so please feel free to contact me or make a posting.

Many thanks,

Rob

I have some specifications in a book at home, I'll convert them tonight when I get home if someone doesn't before then.

The only thing to bear in mind is that the studio models were not all to constant scale, either with each other or their surroundings.

The length in my books is states a length of 25 foot. Which at 1/72 I reckon works out at 4.16 inches.

Cheers thanks for the info,please can you tell me how to work out the lenght from the technicle dimentions you have,as your book states it was arout 25 foot long,how do you get to the figure of 4.16 inches long if it was in 1/72 scale.
I don't disproove your calculations at all i am curious to how you worked it all out,thats all.

My son has the Dinky version of the SPV and there is a captain scarlet figure inside it which looks about 1/72 or 1/76 scale,however the vehicle itself is about 5-6 inches long,is the dinky toy version out of proprtion to the size of the figure?

The Imai kit of the SPV is said to measure 7.5 inches once built-what scale would that be then?

If you could help me further on this topic i would be very gratefull to you.

Regards,

Rob

4mm to the foot is quite close and easy to calculate  :twisted:

Ratch is quite correct in 1:72 4mm to a foot a good guide. With scales everything is proportionate and expressed in a fractions so in 1:72, if something is 72 foot long on a subject, on the model it would be 1 foot long.

With the SPV my data says it was 25' long, so if you convert the feet to inches by multiplying by 12 you get (25x12)=300 inches.

Dividing that by your scale you get (300/72) = 4.16 inches.

The dimensions of the Dinky SPV may be out of proportion but please bear in mind that it is a toy, not necessarily a scale model. You say it's between 5-6 inches, 1 inch in 1:72 would represent six foot on the actual subject.

If the Imai kit is 7.5 inches long and the plans the company were working from was also 25', then dividing the 300 inches of the subject by the 7.5 inches of the model gives a scale of 1:40.

I personally find working in mm easier and use an Ap "Mila's tools" to work out the conversions.

But again Gerry Andersons models were notorious for changing scale and proportions, we were most likely too young to notice at the time.

The dimensions I have for the SPV are:
Width 8'
Length 25'
Unfortunately no height quoted.

There are actually two different IMAI SPVs, one much larger than the other.
The smaller one comes in a twin pack with a patrol car - which is out of scale with the SPV.
I have both sets somewhere but right now haven't a baldy clue which storage box they might be in.
At a guess, I think the smaller SPV would be about right size. As far as I remember its in about the 4 to 4.5 inch length

Without wanting to throw a spanner in the works, isn't the Imai Angel Interceptor cited as 1:100, but a very similar size to the Airfix kit which claims to be 1:72?

Scales seem to be very uncertain indeed when dealing with this subject matter.

When I built my Imai SPV (with added interior detail) I worked it out to be roughly 1/48 scale. I too have the smaller kit in the loft, can't think what length it is
