Hi GabeZ,
I get the motor overload message all the time, I believe it to be code added to the FW to prevent the battery from going into its self-preservation mode. It seems to occur when the battery is put under load, I would rather this than have the battery switch itself off. There seems to be many of us seeing this and recently I have made several gentle flights lately taking it easy on the sticks and guess what? No message.
Hi Mark,
If the message popped as a safeguard, and it had nothing to do with actually decelerating against the pilots will, then I wouldn't have anything to worry about. Also, what made DJI re-adjust the tolerances for this without proper explanation of why? I appreciate everyone coming up with theories of why DJI did it and what they think it actually means. But where is DJI when everyone is proposing such theories? Have they ever really validated what anyone has said? So far I've only seen them say that it occurs during aggressive flight. That's like me saying "The aircraft is louder when you apply throttle." Suppose I actually did have a motor binding. How would I be able to tell the difference between one error condition and another if the same warning is used for both? I could do the obvious low flight tests, spin the motors by hand, etc. However, there is no way to actually comfirm it without replacement of the motor (assuming I could actually determine which one with superior guesswork). I would really like to see explanations for these warning adjustments when they weren't necessary before. If I am to fly the Inspire less aggressively, then wouldn't it make more sense to degrade performance with firmware so as not allow it? If I see a battery is cold message, wouldn't it make sense to not allow motor startup until the proper temperature is reached?
I'm kind of old school and simple in my thinking, but if an aircraft pops warnings, then it shouldn't let you perform the action that causes it (within reason of course). Warnings should be reserved for actual problems. Lets say you were new to DJI, but yet you were an experienced pilot. You still wouldn't understand why these messages are popping or what you did wrong. Nowhere will you find these in their manuals and nowhere (other than forums), will you even begin to understand what could possibly be happening. Also, although their phone support has come a long way, it is still sub par. I had a couple of long discussions with some of the representatives and eventually came to the conclusion that most didn't even read their own manuals. I was citing pages and explanations that even they didn't even know existed. Try asking a representive for an explanation about why battery status doesn't quite match up with their low and critical battery settings that the go app lets you set.. You'll get several different answers. For example, I can tell you that if you set your low battery setting to 15% or lower, regardless of how close you are to it or what your altitude is, the aircraft is going to land and not prompt you other than to say it's landing. As I understand it, the aircraft should never do this unless it determines it doesn't have enough power to safely land or your critical battery setting is actually 15% or lower. I've tested this at hover and I've tested it on a counter top without blades. Anyway, it's neither here nor there......
Many forum members will simply say to just ease up on your sticks, keep your batteries warm, and monitor your battery levels (just that cut and dry). But that still doesn't fix the problems with the aircraft. It's simply a workaround.
Oh! And to answer the other question, I calibrate the compass every flight. I don't commonly fly in the same spots consistently, and this last flight was done 225 miles away from my last flight location. |
