What is the weight of this drone?? I have 1700 kv motors on my 7inch and was wondering if I need a throttle limit when running 6s with a the 60 amp hobby wing esc. I guess around 700 grams because no the gopro?

~560 dry (without battery)
I got a throttle limit of 60% on 6S, punching it I pull ~160A, the T7056C are very very aggressive props. When these props are trashed, I'll try Dalprop F7 (7051).
I'd set your limit at 75% and try a bit. I don't think you'll fry your ESC, a 60A 4in1 ESC means you could do 240A.
Anything longer than a few punch outs and your battery will be gone first ;).

In hindsight, I should have gone for lower KV motors, but I first wanted to go 4S, but batteries sagged to fast, so I went 6S...

That is a light 7 inch quad!! Im running 4s 1500mah now, but have a 6s 4000 mah battery laying around. Sounds like ill use a throttle cut if I ever use it because my drone would probably weigh 1300 grams with it or so.

It's just a Mark4 5" with 7" arms (the motors are quite heavy tho).
I've also tried:

  • 4S 4000mah LiPo (from my plane) and was okay
  • A 6S 4000mah LiOn pack gave me just shy of 30min of speedy crusing.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
