Hi AstroDad.

No, it's not bulky at all. It's about 2 inches long, 3/4 inches wide, and about 1/8 inch thick.

I usually cut a slot the size of the LED strip in the side of my fuselage somewhere in the radio compartment. Then I paint the balsa with flat black paint, then put the Voltwatch inside the fuselage with the LED's facing outwards (of course.. ) with the green forward, red toward the back. So, you read it left to right. I then take a small strip of clear monocoat and put that over the hole, and voila.. you got your voltwatch mounted, clean and simple. Oh, I tape it to the inside of the fuselage, hold it there, with a strip of 1" Blenderm adhesive tape, available at any good medical supply store. The Blenderm is strong, flexible, and easy to use.

Here are the spec figures from Tower:

Length: 1.65" (42mm)
Width: .63" (16mm)
Height: .16" (4mm)
Weight: .15oz (4.3 grams)
Current Draw: approx 4-34mA

If you look closely enough, on the left side there is a 4.8 volt - 6 volt slide switch to select your battery type.
