What the photos show is my plane with a 4.8 pack using 5 servos in a snap roll, throttle is closed but I guess that still counts as 6 servos, three of them are digital Hitec and three of them are analog JR. When I release the snap roll switch the VW lights drop to the bottom LED showing a full charge. I did a stupid and mounted it aft and under the wing so I tend to forget to look at it before every flight. My bad!! These are fun to take apart and put the LEDs behind the instruments in scale planes. I once did it in a nice Hell Cat scale plane. If you have a real cockpit and canopy it's a good place to mount them so you can see it. This is an old Hots fun fly plane with no real cockpit.
