in scale 1:6 a steel Tiger SHOULD weigh 0.935 : 3.37 = 278 kgrs.

Thanks for all that info, It does help just dont know how yet.

Have applied the formula to my 1/12 scale M41 and in 1/6 scale it would
weigh 111 kilos. At 1/12 that becomes 14 kilos.

At the moment its a few kilos heavier than that but I have thicker steel
armour than the original and a few other bits that could have some weight
shed from them but overall the formula seems to be accurate.

At 1/12 scale the diameter of the springs are 3.1mm and initial driving
tests done today suggest that they are well suited and a lot of swaying has
been reduced when accelerating or braking. Measurements taken from line art
from a chaffee suggest that is the scale diameter of the rod but dont have
any actual figures on that.

The M41 like many US tanks from the last years of the war onwards had copied
the German torsion suspension.
M41's weighed about 24 tonnes and had 10 torsion rods with a top speed of
72kph, thats pretty fast for a 55 year old
