Hi Peter Motor power depends on weight, rolling resistance (very difficult to judge), battery size (which affects weight), the speed you want to achieve, and the torque you want to generate.
The easiest way is to look at a tank on the website that is similar to your projected tank, and use the same, or similar, motors. 15 kg is very light. My tank (T057) has a fighting weight around 20 kg. It has two De Walt right angled drill motors which are 12V 190W each. It produces a speed of about 3mph (4.8 km/h) at the faster drill setting. If you look at some of the US tanks (particularly), they are using much bigger motors (250W-350W) but with bigger weights (150 lbs- 68 kg)but looking at some recent videos higher speeds (I'm guessing round 9 km/h.
