I was thinking the same Shen wrt the open IR unit it has. James was looking for Tamiya Leo instructions if anyone can help him out. The VS kit is nicely detailed for 1/24 and runs well, the engine sound is a little cheesey and the firing recoil is the typical tank jerking we see from China. It runs smooth and control is not bad, the turret rotation and gun elevation have some whirring noises but work nicely. Next is to use it in combat and see what the fun factor is.
