How the Battletrax combat system works

We have attempted to replicate as closely as possible the prototypical commands and process followed by a WWII tank commander.

The US Armored Force Field Manual of Tank Gunnery published in April 1943 gives the following formal commands when engaging a target:







"Eight hundred"


Alerts Gunner

Indicates Target Type
Indicates to loader to use armor piercing ammo

Indicates position of target relative to barrel position

Continues traverse until gun aimed at target

Indicates estimated range in yards

Authorises firing


The Battletrax radio system is independent of the RC system controlling the model. Although both can be operated by one player there is advantage (and increased enjoyment) if the player driving the model takes on the role of Commander & Driver and a crew member takes on the role of the Gunner operating the Battletrax fire controller.

The Commander identifies the target to the Gunner, specifies the ammunition to be loaded, estimates the range and orders "Fire!"

The player inputs the data into his Battletrax fire controller and the virtual crew, via the unit sound chip, confirms the range (or change in range) and the player presses the "Fire!" button. The Battletrax fire controller operates the model's barrel recoil.

Using information from the model based GPS the system compares the Commander's range estimate to the actual range. Taking into account the height of the target and the trajectory of the firing gun the system declares a "Hit!" or "Miss!". The virtual crew provides feedback to the Gunner as to whether the "Miss!" is "Over!" or "Short!". The Gunner conveys this to the Commander who can then "bracket" his fire by ordering a range adjustment for the next shot e.g. "Up 200".

On obtaining a "Hit!" the system determines at what height and where the shell hits the target. On board compass and turret encoder provide the orientation of the target's hull and turret independently. Therefore the system can identify the thickness of the armour at the point of strike. The angle of strike is calculated by combining the vertical slope of the armour with the horizontal angle of attack. The US Army Armor Basis Curve is applied to determine the effective armour thickness at this point.

Using historic gun performance data the system determines whether the firing gun can defeat the armour. The virtual crew will report "Target Destroyed!", or that the shot failed to penetrate the armour. In the event the target is destroyed the system automatically triggers the detonation of a stage pyrotechnic in the target tank.

Appropriate sound effects for cannon fire, shell hits and a tank brewing up supplement the virtual crew reports.

The system provides for over 100 types of tank and your model can be programmed to represent any individual type you want e.g. a King Tiger, StuG, T34, Sherman Firefly etc providing for over 10,000 different tank v tank permutations.

In addition a whole array of anti-tank guns are represented
