Without Gimbal and camera whole setup weight is about 1390 grams and I get about 15 minutes flight time.
I bought futaba which is a very good RC tx/rx but dont go with it as it is very costly, and you can see at my setup price u can go with a DJI phantom 3 which is very stable
currently iam upgrading my setup to a simple aerial platform soon ill post pics
It's hard to say what your AUW should be with these motors. I can find no specs that show thrust. You want an AUW of 50% of the combined motors thrust. With this size motor, generally the rig should be in the 1.2-1.6kg range.
680 sunnysky,1047 or (1365 if you can fit) on 4S.Prepare for takeoff.
P.S.
I think your parts list is mixed up or wrong somehow?
I had some issues handling this parts list as the parts come from stores that don't use US currency. I'll have to revisit this and see if I can make it work.
