My setup:
Phantom 2 v2 (base model)
eachine light 2D brushless gimbal
Xiaomi Yi Action Camera
Turnigy 1000 mAh, 20C 30C, 3S, 11.1v LiPO battery (used to power 2D gimbal)
Weight (approximate values):
Phantom (w/Battery & Propellers) 1000g
Xiaomi Yi Action Camera 71g
eachine light 2D brushless gimbal 160g
Turnigy 1000 mAh, 11.1v battery 79g
--------
1310g
I am slightly overweight, as DJI rates the Phantom 2 max takeoff weight at <1300g.
No soldering necessary!
I used velcro to attach the gimbal battery to the underside of the Phantom 2 as depicted below.
I used rubber bands to attach the Xiaomi Yi Action Camera to the 2D gimbal.
Results:
The extra bulk of the gimbal/battery/camera results in a bit of sluggish response compared to the clean Phantom 2 configuration. The sluggish response is more noticeable under windy conditions. The flight time is reduced from 20+ minutes in the clean configuration to just under 15 minutes. (I start flying with a full battery charge, or 4 Green bars, and land when the second bar starts flashing, or one-and-one-half Green bars.) There is occasional gimbal "wobble" in the 1080p video. I have not yet changed any gimbal values via the SimpleBGC program. Overall, as a survey/surveillance video platform, it works well.
Future:
I plan to post a brief video later this month.
Fiddle with the 2D gimbal settings via SimpleBGC GUI v2.2.
Open up the Phantom 2 to attach the pitch control cable from the Naza to the 2D gimbal.
