Just received the 1/16 tanks. The T34 is fairly basic and is powered by half a dozen AA batteries, no idea of manufacturer - I think it may be going on the Bay of Fleas. The Pershing is much more substantial with metal sprockets, big battery and smoke, BB gun etc. No controller though - do you just buy one off the net? Are they different between makes/models?I've got the Trumpeter 34/85 and it's a nice model. I expect if HL do one it's a RIP-off of theirs, so should be good too. The Pershing is one of my favourites. They can be pimped up with better controllers and sound effects if you want to.
