This is the current project started with my son. I have always felt that the Leman Russ tank in all its variants has its turret mounted too far forward. Any shell deflected upwards by the sloped front armour will hit the gun or turret. To reduce the risk of this I have tried to stretch it adding 1cm of decking in front of the turret, and pushing everything backwards.
The rear engine and decking need to be tidied up with some smooth lines and a bit more added ablative armour.
