This hexacopter frame from Carbon Core is very similar in dimensions to the S800 from DJI. It is however the lightest frame we have come across here at Heliguy - it weighs in at a mere 760 grams.
We have two frames available complete with Carbon Core leg-sets. It's possible to use S800 retractable legs should you wish however - this would allow for seamless integration with a Z15 Gimbal from DJI.
The 950 is manufactured in the UK to a high standard - it really does look superb in the flesh with a nice glossy carbon weave. If weight is a concern in your Hexacopter build then this frame would be the perfect solution.
Be sure to give us a call if you need any information.
