Hmmm.....was the GPS locking properly? I mean are you getting the 2 green led blinks before flight? Sometimes there are issues with GPS locking, in that case the position hold is not proper!

Yes drifts may be due to various reasons like faulty GPS module, problems in motors or ESCs, disbalanced frames and many others. My suggestions, try to follow the installation steps perfectly and in proper sequence. Specially the calibration parts. Hope for the best. Good luck! Thumbs Up

Great build gunnu...but i would advice you to not put the fpv camera on a gimbal if your not planing to save the downlink and not flying LOS...because it will help you judge the actual way your quad is reacting to the wind and the changes the FC is causing through you fpv screen or goggles..
Keep it for a mobiuis or some kind of HD cam

Hmmm....the weight is killing the flight time! It is the most challenging part, how to increase the flight time in quad! With my config I get hardly around 10-11 mins with a 4S 3200. My quads AUG is around 1600gms with the Nikon camera that also w/o gimbal!
Is it possible to shed some weight? Are you using the flight battery for all other accessories like VTx, LEDs or Gimbal control or a seperate one?

Well, difference in weight will effect the flight times by few mins. I guess try to use a smaller and lighter battery, may be Zippy compact or Turnigy nano tech 3S 1200 or 1500 mAh. I guess 1200 or 1500 is enough for your LEDs and other accessories.

no just check the magnetic-declination of your place.. (for an example- concider magnetic-declination of your place is positive+1° 31' than rotate your GPS module in clockwise direction.. and if negative than in counter clockwise direction.)
for better understanding watch this video

@gunnu I guess u r using 810 Kv motors right? What size props are you using with 4S? 2kg AUW is a pretty heavy craft. Best way to increase flight time is to use much lower Kv motors (300-600) with larger props (14" - 17") with higher battery like 5S or 6S. This way you can get heavy lift plus more flight time. Ofcourse the expenses also rises alogside.  Head Scratching

Not sure upto what size prop your frame gonna support, but with a 15" prop and a 380 KV motor and a 6S lipo, will give you huge lift which gives you a freedom to add lot of stuffs and accessories to your quad as well as around 25 mins of flight time!

Well done gunnu!  Clap Great stable flight. Have you tried with the gimbal and camera? What is the total flight duration? Now you have to work on how to extend the flight time!!  Roll Eyes

Well thats not bad at all! Is it just hovering or full length flight? Nyways, 16 min with 2kg AUW is pretty good. Keep it up!  Thumbs Up
My AUW is around 1600 gms and I get around 9-10 mins with 3300mAh 4S, 9" props.
