I am using both the Plettenberg EVO 30-10 and the hacker XL 50-14 L in a Oxalys from ZN-Line. My experience is that the Plettenberg is using a little more amps at full throttle than the Hacker, the EVO I have 90 amps and the Hacker 75 amp. With the EVO i have a bit more flying speed than with the Hacker. Both have enough power, but i thing that the batteries better like the Hacker... The Shulze regulator is very easy to adjust the breaking in down maneuvers, and i think that is works a little better than the break in the Jeti/Hacker regulator. I have used the Hyperion VX5000 cells with both 20 C and 25 C and there is a lot of power in those batteries and i have had no problems with them.
The Plettenberg EVo is easy to mount and has no maintance were the Hacker is a little more difficult to mount and you have to change the grease in the gear box, but that is easily done.
