Nano 5.8GHz Tx w/ wire Ant. These are the lightest versions of the Nano transmitter, featuring a wire antenna to save weight. They weigh around 7 grams. With 100mW output, they do not draw any more than 1 Watt of power from a battery pack, so that's less that 100mA from a typical 3 cell LiPo. The end result is you'll need a smaller battery pack, again saving on your all up weight. No voltage converters are required - the integrated switching power supply will efficiently handle 6-15Volts Using similar circuitry to the larger Stinger transmitters, the image quality is excellent, limited mainly by the quality of video from your camera. Seven channels are selectable using the dip switches on the transmitter. Use this transmitter with a Nano 5.8GHz receiver (upgradable to a diversity receiver) or a Yellowjacket Diversity receiver. These transmitters are made in USA, specifically for R/C aircraft use. They are assembled from quality components and are very robust. Perfect for use in Aerial Photography applications or FPV flying. Leads for power and video are supplied. Integrated wire antenna. 6 to 15Volt DC power required (2, 3 or 4 cell LiPo pack). 100mw power output Compatible with PAL & NTSC video. Excellent range for R/C use even with stock antennas.
