Hi JB,

The two batteries / reg`s is for redundancy ... Just in case ... Get the powersupply -issue out of my mind
The main reg is at 5.7 v and the backup at 5.1.

Before the conversion,using YS 160DZ , the total weight was 4490. After the conversion ;5050 ...
Still there is relatively easy to get rid of some grams, when needed ,to pass the limit. I am using 5000 mah packs at 1270 grams, a bit on the heavy side, but work great at an lower cost ...
All in all, the flying weight is about the same as with ys, and the power / flight time is awesome when running the batteries down to 20-30% (25% average) depending on weather condition/ style, flying P-09.

Actually, i have set up my Powerdrive-system to act like my DZ .In fact; it feels just the same as flying 160DZ ; plenty of power, agressive, and smooth at the same time.

I am really suprised how good this work .
