Hmmm...we understand....we'll wait.....btw how was the flight experience?

gunnu · April 01, 2015, 01:14:42 PM

flight experience was good.. quite stable.. but not satisfied with flight time..
8 to 9 mints with 4S battery 5000mAh
weight around 2kg

meet2ami · April 01, 2015, 01:20:02 PM

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?

gunnu · April 01, 2015, 01:23:56 PM

yup i use different 3S 2200mAh battery for lights.. without this battery it weight around 1.7kg.

How much difference does that make in flight time, without extra batteries?

gunnu · April 01, 2015, 01:44:33 PM

will test today...

meet2ami · April 01, 2015, 01:47:55 PM

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.

gunnu · April 01, 2015, 01:53:24 PM

i have few NCR18650B batteries... and led working voltage is 7 volts to 12 volts. will give try with two NCR18650B batteries in series and one battery weight around 40g i think.. than two battries will weight 85g with wires and connectors..

what was the cause of drifting in GPS mode ... how it got resolved?

gunnu · April 01, 2015, 02:00:19 PM

GPS drifting issue resolved after advanced IMU calibration and presicion setting of magnetic-declination of compass..

rastsaurabh · April 01, 2015, 02:59:23 PM

What was done for magnetic-declination.

any place where the inclination values are entered?

gunnu · April 01, 2015, 03:06:19 PM

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
