Lets say two Zippy Parallel so 2108g is pretty heavy already.
I am predicting this now from infos in different threads. Z15 with the cam a NEX 5 standard around 1.4 KG. The frame everything on without WKM or any VTX etc around 2.7KG.
So:
Z15, Cam = 1.4 KG
S800 all on = 2.7 kg
WKM extra stuff = 100 g min.
Total 3.9 KG
Two Zippy since lighter than the nano and more realistic due to price also: 2108 g
Total setup around 6 KG.
I would wait for more infos in the motors and whats the max payload two, parallel could lame the bird.
And of coarse would be interesting to know what draw the S800 has fully equipped concerning c rating of the lipo

Thanks Boris, very helpful info, I think I will go with Zippy pack route, Nano tech is too easy to damage, Maxamps is too expensive.
But 6s low KV motors the A will be pretty low so all of the C rated lips from above should work.
can anyone speculate the amp draw at hover? 6S lipo and 340KV motor, I would say 7-8 amp for each motors at hover, make it less than 50amp, dont think anyone will do sport-flying with your S800.
Geoff
can you tell us the amp draw?
I will be buying in some Maxamps 11000 mah 6s Lipos for the S800 I think they will be without doubt the best bet , although not the cheapest the weight saving will be worth it .
