Z-tek
Normal version
The Z-tek is second most powerful motor in Stock RA2. It is plain white, with a black rear, weighing 25 kg.
High Power version
The most powerful motor in Stock RA2 is the High Power Z-tek (commonly abbreviated to HPZ-tek or HPZ). It is slightly longer than the Z-Tek and features a red ring on its white side.
The HPZ-tek is widely used in the RA2 community because of its power (it is the motor with the best power/weight ratio). It draws as much electricity as all other motors and has twice it's power, for only 5kg more than the normal Z-tek. It weighs 30 kg.
The Z-tek is a rather obvious reference to a real-life motor, the E-tek, which even looks like an E-tek. Notably, the E-Tek is available in DSL.
1 black can power 4 HPZ teks for 3 minutes.
