First is anybody else flying the X8?
I bought mine RTF to do Aerial vids with a Hero 3D rig. I bought an brushless RCTIMER ASP 2-Axis Nex-GH5 . It was fairly easy to get a sound install and finally figure out how to power up the gimbal and it's seems to be working fine. I had to add landing pads to the base of the X8 landing gear to give the Gimbal and camera space for landing.
I have begun flight testing the rig and found the simply to adjust the COB on the x* I hang two batteries as far aft as I could. they were two 3s 4200 mah. My early flights were short and damaging. As I have now learned to view the flash logs and T logs I could see that I had a serious power deficiency and he throttle mid point was way low. I have to run the throttle hover mid point at 600 to get loiter stable. Is that too high? I found I was running routinely at 70-80 amps with the 3s batteries that came with the machine. Flight time was barely 4-5 minutes was precipitous drop at the end.
I decided to try a 4s battery 4000mah and have noticed some improvement in throttle levels and stable fllght times. I think I am on track with the larger 4s for the added weight but I'd love to hear other ideas. One thing I have found out is it's easy to kill a good battery if you run the voltage below levels and I've done it to three already when I try to get the maximum flight time.
I still have no confidence in this rig for a mission. I have been hover around the backyard. Trying to get it stable and get predictable flight times. When the juice runs out this thing drops like a stone and unlike my Phantom there is no real warning time.
I can only conclude I need more and larger batteries to get my flight times up. I am running the stock rig shipped by 3D Robotics.
Is there a mentor out there that would tolerate my incessant question while I try and master this very hard to fly rig?
I attach an image of the present set up with my ears open for better ideas.
