all my models have -among other shown values on my transmitter- a real time current measurement via telemetry (the other transmitted data are e.g. voltages of each LiFe cell, temps of motors and ESC and -important- the consumed capacity of the driving battery). It's rather astonishing which peak values of driving current you can see and under which conditions they occur.
My non-Armortek models are equipped with spur gear motors of either 350 watts or 450 watts, similar to the spiradrives. The power consumption is also similar to Armortek tanks. My Armortek Jagdpanther actually has dead lead acid batteries and is not operational, therefore I will use data of my other models.
Perhaps discussing my so called Pöti (king tiger with Porsche turret) with about 160 kgs and grippy steel track links showing the following data:
- driving ahead at flat and plane ground: 4 amps (for the whole tank!)
- driving ahead at an ascent of perhaps 10 %: 10 amps
- driving a turn: 15 to 35 amps, depending on kind of surface
- table turn in rough grounds: up to 55 amps, which means an overload of 50 % to the motors.
You see that climbing moderate hills is not as power consuming as turning in the plane. The reason is that when driving ahead the tank treads lie immovable on the ground and the roadwheels roll over them, but when cornering each track link is moved across the ground, while the whole weight of the tank bears upon the track. Therefore much more power is needed to move a tank (original and model) through a turn than driving straight ahead. But I was astonished that the difference makes up to 15 times more!
