ATTILA (Augmented Arcjet) 0.625m part is wrong weight #75

The weight of this part is 1T which is the same as the 1.25m part.
Judging from the (somewhat inconsistent) scaling of other parts, they should probably weigh somewhere between 0.125T and 0.275T. Their current weight makes them pretty useless.

Look at a bit of the data, and the weights work differently then I assumed they would.

I assumed weight would be in relation to size^3 (cube)

For example I take the ThermalRocketNozzle

rescaleFactor = 0.25 (62.5cm)
0.625^3=0.244140625
0.25^3=0.015625
mass = 0.11

0.25/0.015625=16

rescaleFactor = 0.5 (1.25m)
1.25^3=1.953125
0.5^3=0.125
mass = 0.4

0.5/0.0125=4

rescaleFactor = 1 (2.5m)
2.5^3=15.625
1^3=1
mass = 1.5

1/1.5=0.667

rescaleFactor = 1.5 (3.75m)
3.75^3=52.734375
1.5^3=3.375
mass = 3

3.375/3=1.125


But there is something curious:
1.5/0.4=3.75
0.4/0.11=3.64
But see if I throw it around:
1.5/3.75=0.4
0.4/3.75=0.106666666 and so on

So the weight I expect is 0.27
