Of particular interest to anyone buying a tank sporting the v7 series of Heng Long controllers, could be the run-through of controls, and tweaks via button combinations (speed; volume; and so on). Of interest to me was the huge gun which not only fires BBs, but also has barrel recoil. I'd like to see how that works, and whether it's anything like the system Taigen used on the Tiger 1.

The tank also has IR capability. This is the 'Pro' model featuring metal tracks, swingarms, idlers, and drive sprockets, etc.
I think Haya sells the model under a 'Platinum' designation, for around £200- which doesn't seem unduly pricey.
