Install them as close to the ESC as possible on “ALL” the wires shown. One larger choke can have several wires running thru it. Pick the ones that fit the space. Larger chokes provide better function. Since the ESCs are in each nacelle, install the chokes as near each nacelle as possible.
For good measure, put a small one near the green ring choke, too. It can’t hurt.
Below is an example of the installation on the AL37. The ESCs are just below the battery tray area. You can see how several wires run thru one choke.
Note: The photo below shows the motor side of the ESCs.
You don’t need chokes on the motor side wiring. The motor side puts out less RF noise. The other side of the ESCs is more important to choke. In the AL37, both sides of the ESCs are easy to get to, and it can’t hurt to choke both sides of the ESCs.
I add extra security with zip ties to keep them clamped shut.
