Great!

Your regulators have been used ( and still are ) by the Norwegian pattern community (me included) for many years and flights without any problem, rock solid, a component you can trust for sure!

I guess i am too careful about batteries sometimes ... changing them too often .... Actually, my worries is about mechanical failure with them, shaken by the ys-stroker ...

Now, in this Lithium-days, i guess it is possible to use both primary and secondary batteries within the same weight as the "older" setup i`ve been used ...

Ok, i go for Li-po ,both packs then ! It should be possible to make an balance-extension cable , reaching the aft mounted pack ...
