Hi Stek

I have two Integral's (Composite-ARF), in my opinion they make a fantastic electric powered model. I don't know the exact weight of the ZN version, but I have had many ZN kits and their wings and composite work is typically quite light. I cannot see any reason why you would not make the weight limit with it.

For reference my Comp-ARF Integral was setup as follows

Pletty Evo
Schulze 32.80 KA
Futaba R6114 fasst rx
Futaba, x2 BLS 451, x1 BLS 351, x2 9650
Thunder Power 10s 5300 Prolite V2 packs
Thunder power 2s 900 receiver battery
Tech -aero regulator
APC 21x14 prop
Tru-turn 3.25" light backplate spinner

My weight was 4940grams with that model.
