Just got back from another run. This time using dual 1700s just to make sure my direct power mod isn't the culprit. Dual 1700s actually outperformed the Titan 7000.
Airdata UAV - Flight Data Analysis for Drones
I'll be waiting to the more results from the others who ordered.
EDIT: I have to do a full calibration. Not sure if it was due to opening up the Mavic or something else I did earlier this week but there were definite control issues.
I had one more time to think about this. I would like to think calculating a flight time isn't hard and some other difference could be affecting the differences in results between different birds.
Then I thought of the firmware difference, not the firmware on the bird although that may make a little difference. Specifically the firmware on the mavic batteries.
I can't explain the "electronics" behind it and how this could affect the results being different from different birds since I've been told not to talk about electronics.
But in short, it has to do with how the power would flow and management on how electronics control that flow. If DJHood ever shows back it might be something to ask about and compare.
Also basic metals and principles behind electronics like taking the shortest path and the difference on each mod to get the GPS and compass siggnals child have an affect, types of metals being used, how long the metal strips are and types of wire.
When I say wire, they have copper stand wire, but cheaper wire has come on the market also that is copper plated steal, or copper plated aluminum.
The copper plated aluminum is easy to test, take a lighter to the end of a wire strand and if it burns away it's aluminum. Different wire and metal shunt parts used to attach to the pin out under the battery will cause different resistance and direct the flow differently. In short heat battery power gets used first, the mavic or the titan.
If the mavic get used first then the system will read that and want to land near low battery. If the Titan is used first then the mavics battery power is a slower current allowing a longer flight.
Ideally the best setup would be both used equally in a perfect match at the same resistance and flow of current to prevent one battery typemtrying to charge another. But people buy parts and wire from different sources, I've even seen a video of someone using brass metal plates and not copper. Brass would heat up more and be a loss of energy compared to copper.
The best would be nickel, but with a mod like this for the pins on the bird and bending with constant plugging and unplugging of batteries more strength would be better. So nickel plated steel would probably be the best.
I'll leave it at that for now, I don't want to get to technical or electrical and be accused of going off topic when I'm just trying to help.
