Hi Dave,

The Matorro version has a scale length barrel, but I don't know how good the electronics are - but if they are based on the electronics and gearbox of their king tiger you may be in for disappointment (I have 2 plus their SturmTiger, all of them have have issues!). The battery is also too small for a tank with metal tracks.
If anybody here has one already, feel free to set me straight on these points...?

If you don't want to mess around inside I'd recommend the Heng Long from RCCommand. Its more money but the internals are much easier to get spare parts for (rccommand stock them all) and you'd be happier with how it runs. The only downside is that the gun barrel about an inch too short and the mantlet is flipped 180 degrees from where it should be - neither of which really detracts from having a (reasonably) robust rc tank. The only drawback to having the metal tracks and gears is that you'll need a cooling fan on the control board if you want complete peice of mind when running around outdoors - there are plenty of tutorials around here on how to do that.

Hope this helps?
Mart
