Thanks for sharing. Good info.
Now how to decide between the X and S models?
I see the S color tabs. How difficult are those tabs to remove?
The X looks triangular vs S is diamond. Benefit to either for connecting/disconnection? One give more surface area?
X uses screws, how easy are they to install? Hold up after many connections?
With X experience only, I don't think the shape is of consequence either way. Just a design and maybe aesthetic preference.
The screws are finicky to install the first time as you are tapping them through the plastic. After that, the removal and installation is fairly easy. I would not recommend tightening one screw down before the rest, rather, install them progressively in sequence. Also, keep the plastic cap seated while tightening.
I wouldn't worry about holding up on either style.
I chose the 5 simply because it meets the power requirements for the 516. It's at the peak for the 696 but I'll never get it there, haha. I've never pulled 60A out of the 516 and everything stays nice and cool even after back to back flights. Alas, I'm not doing 3D!
I don't think you'll go wrong with either.
