WHEN THE Federal Aviation Administration, a few years ago, put out a recommended model flying altitude limit of 400 feet (where possible) it soon became obvious-and still is-that many fliers have no idea how high this is. It is of interest, therefore, to help make this altitude more "visible," if only to settle arguments. It can also be very useful to know, for sure, what the altitude looks like in terms of a given model field and typical flying there. The altimeter described here can be very helpful for such purposes. It can also be used for attempts at RC Helicopter records. But don't look for it to help with RC Power records with conventional aircraft-that record is well over 20,000 feet! However, the RC glider altitude record is within range of this altimeter-it is calibrated to 6,000 feet and the current world record is 4,988 feet.
