I sent a message to 3DR support about a week ago and I figured I should just post some questions I had here.
I have this kit on the way today, with the 850kv motors and I am wondering about some things.
1) I plan to run this with a 4S 4000MAh lipo, I have read on different forums that the 3DR apm power module shouldn't be trusted? I would like to be able to monitor the voltage as well as the amp draw, what are everyone's thoughts on this power module?
2) I plan on using a small 5.8GHz tx for video on my quad along with a small ccd camera and a second smaller (1000mah 3S) lipo pack to power them. Are the 850kv motors with the 10" APC Props going to be strong enough for this configuration?
If not, I am thinking about running something like the T-Motor MT2212-13 980kv's with 9x4.5" APC props or possibly the MT-2216 900kv with 11" APC props.
I have been running a hoverthings flip fpv quad with the same fc and gps for a while now, and recently was able to get it tuned correctly and it works great with the latest 3.0 firmware, and it uses the 980kv t-motors with 9" props, one of the problems with this type of frame is to get everything mounted where the apm doesn't have interference issues, I ended up mounting it on the very top of the frame, which I am not comfortable leaving it exposed like this, and I really don't want to install an external compass module. One good crash and it wouldn't be good for the APM.
I'd appreciate any advise, Thank You
