Nate is correct about having to solder the capacitors in place, and I do as he says and just use the caps from left over motors (like from nylon gearboxes) and I've been told the yellow ceramic caps are better than the brown wafer type, and I was also advised by Kevin at RCTA to add a third cap, bridged across the two motor terminals. I tried that and did notice a difference in reduction of interference, so now it's standard on all my tanks. I'll do a video on that so you guys can see exactly how they go, and while it really is a good idea to get a pinion puller, I have an emergency method using a mini torch and an old pair of cheap wire strippers. I think I did a video on that but I'll have to look for it.
