It looks very realistic ! Smooth turns of the hull and turret, buildup when hitting obstacles - a very high level of realism. It remains only to make the horizontal stabilization of the gun.
I think i read a tutorial that if you take the suspension arm off, you will find a torsion spring. One end of it fits into a hole in the hull and the other on the arm, which gives it the springiness. If you drill a small hole at the 12 o clock position i think, when you put it back together, the spring will be under less spring tension, causing a slightly softer suspension. Havent tried it myself though.
U need to research more there's 1 place that has everything an Much more!! U don't find if U don't look. Your Not Gunna get it all handed to U on a Silver Tray!! Like my Abrams has everything here + citv RC controlled, full Trophy system, CROWS System RC controlled 2nd bussel rack electronic jammer witch is the thick antenna, full gyro controlled barrel, Super Bright flash an barrel smoke, TUSK ll anti laser coating on all viewing ports witch makes the viewing ports change colours at different angles etc etc. Look harder an you'll find all this an more in 1 shop, but no one showed me l had to find it for myself!! Put the effort in an you'll be Rewarded!!
