AstroDad.. on one plane, one that had a removable canope, I actually mounted it in the "dashboard" so the "pilot" could see it. Looked pretty cool. I also cut through the thin ply to make it fit in.

It just takes a little time and careful cutting to put it wherever you may wish to put it. The only 'requirement' is that it is clearly visible when you need it to be visible. Obviously, you can't see this thing from the air. It's not for that. It is a 'before and after' device in which you get the 'warm and fuzzy' that your battery pack(s) are functioning and have a decent and usable capacity to continue flying.

What I also do with mine is this: Upon initial installation, I use it as a tool to check for any binding in the linkages. I turn everything on (this is on the 'bench') and then, systematically move each stick to control each and every conrtol surface plus the throttle, and any other item that may be attached to the battery that causes a load. Moving the sticks will cause the battery draw to change due to servo movement and servo load, and thus the LED's on the Voltwatch will flicker. If I get a hard flicker.. movement to the RED for instance, when moving the rudder, for instance, I know that there is a bind in the rudder linkage somewhere and it needs some attention. The same goes for all other control surfaces.

What is nice with this is especially true for the throttle. We often have a problem with pushing or pulling the throttle linkage to far. So, when we do that, the servo will strain to continue pulling the throttle beyond the stops, so it will begin to draw excessive current when it reaches the throttle stops, full and closed. So, this becomes a tool for setting the throttle servo throw to manage throttle movement and insures that you have full throttle when you move the throttle stick to maximum, and that it closes all the way when you pull it back. AND, the adjustment is made to insure that it does not go any further than that, on either end. Thus, no binding, no excessive current draw from the throttle servo.

I can assure you that there are many RC'ers out there that do not pay attention to that, and as a result, when going to full, for instance, their servo wants to move further than it can based on the linkage adjustment. So, the linkage will flex, or bend, and the servo will strain, and.. yep, you got it.. draw more battery current.

So, it not only gives you that warm-fuzzy feeling before and after each flight, but it also will give you a tool for quickly determining excessive or adequate (acceptable) current draw for adjusting your linkages. Sure, other devices will do the same thing, but none, in my estimation, is as 'cheap' (meaning inexpensive), easy to install, and easy to use as the Voltwatch is. And, it looks kinda cool too!!
