Hey guys, I picked up another Inspire 1 and it showed me a glaring issue with my Inspire 1 Pro.
The Inspire 1 Pro will not turn "flat on axis", ie, it basically wallows when spin on axis in the air.
I landed the aircraft, and started the props on the ground and noticed the back right (with the aircraft facing me) props spinning noticeably slower than the other 3. I took it in the house, pulled the props and started it on the table. I can slow all three "full speed" props but the 4th one (the slow one) with the same amount of pressure stops. It restarts when released, but it is obviously weaker. (Side-Note: I started the V1 and the motors feel exactly like the weaker one on the "Pro")
Also, the ESC cooling fins underneath are warmer on the "slow" motor compared to the rest.
Now, my concern is I was sold this setup second hand as a Inspire 1 Pro setup. It has the X5 gimbal support setup, it also came with a GL658B controller and the "feet extensions". Beyond that I have zero way of knowing if it is an actual "Pro" (ie, v2) setup.
I removed the quick-release hubs and the motors all have 2 holes in them for mounting the prop adapters. There is no writing that states "3510H" or "3510" on them at all. They only have a small ring of print and no Chinese lettering.
Now, the reason I mentioned the other Inspire I just purchased, is because I believe it is a 2014 model V1. It came with 2 GL658A controllers, has a X3 gimbal support and the hatch-pattern carbon fiber arms. On the SD cards and flash drive I got with it it shows dates of 2014/2015 on files (some videos go as late into 2016 and even a 2018 one, but that was it), and the flash drive had the 1.3.x.x controller firmware on it which means they had to update from a 1.1-1.2.x firmware to 1.3 at some point.
Now, I pulled the quick-release adapter off the motors on that one and they look identical to the motors on the "Pro" one I have (no 3510 or 3510H and no Chinese lettering, also 2 mounting holes).
Also, the label inside the battery compartment says T600/1410 FCC ID, the same as the V1 I have.
So, do I "assume" I have the weaker 3510 motors on the "Pro" one? If so I will buy 4 new 3510H motors with ESCs.
If not, then is there any way to be certain that I have 3510H motors and ESCs on the "Pro" one? If I can verify I do I will just order a single 3510H motor and ESC combo. (As I mentioned before, the 3 "full speed" motors seem to be MUCH stronger than the "slow" motor or the motors on the V1 I have, so is that "empirical" enough to say it DOES have the 3510H motors?)
Lastly, in some part listings they show that motor as M4, which is listed as a CW rotation motor, yet when I have the motors running, it is most certainly spinning in a CCW rotation looking at the top of the motor down. Now, does that mean the motors are "spec'd" to run from looking at the back of the motor forward (ie, looking from the ground up), which would mean that it IS a CW rotation motor?
In my "observational" view, it would seem as if the motor in question was replaced with a 3510 motor at some point (would suck to find it was never changed and that DJI shipped it that way) and I am just "correcting" it.
Any and all input would be appreciated.
