This is the improved model of my second drone, "Phobos."http://robocraftgarage.com/robot/qxBCJLX3
Making the "core" of radders and thrusters(Still not perfect).
Adding the THruster Cheeters on the outside the armor.
Fixing the placement of lasers.
According to these chages, Phobos1.01 became more tough and fast Aromored Helium.
At last, I thank jopie110 who gave great advices.
