JR's MatchBox? servo matcher is a revolutionary new way for giant-scale modelers and users of multiple servos on a specific channel to match those servos to a greater degree than ever before. The matching dilemma: Digital servos have brought a whole new level of precision and power to the world of RC flight. Even with all this precision, they are still subject to the inefficiencies that differences in linkage geometry can create when more than one servo is used on a single control surface. Often, geometric differences are more pronounced with digital servos because of their superior resolution and the fact that they produce 100% torque with just 1? of offset. Add to this the minute variations in power output and centering that identical servos of every brand have, and it's easy to see why matching servos to a task is a little tricky. JR's simple solution:JR's new MatchBox is an ideal solution to the "matching dilemma," allowing modelers to match servos with precision and flexibility never before possible. Housed in a case about the size of an R610M micro receiver, the MatchBox plugs into any channel of a receiver that is driving more than one servo. Up to four servos can then be plugged into it and independently adjusted, using a simple selector dial and Increase/Decrease buttons on the MatchBox unit itself. Available adjustments include neutral point (sub-trim), end point, and reversing. It also offers the option of powering the servos connected to it via a separate battery pack. In the case of multiple servos on a single control surface, the MatchBox can be used to match each servo's output for better efficiency, as well as power them separately. This allows the modeler to retain a simple single receiver setup instead of having to resort to using two receivers to keep from running too much current through one. The MatchBox is also ideal for multiple servos on a single channel that are tasked to differen
