If the E-glide competitions becomes more popular the mop2 is more interesting. It has an external current sensor. It does not only record the motor activation regardless of the noise but you can measure and register how much energy is used.
The other types of sensors could "fall" in a place that does not record the motor(propeller) noise when using a power settings that extend the L/D.
You can't remove the current sensor without removing a power cable.
