TBS is stepping up the Long Range / UHF game, with no competition in sight! With the TBS Crossfire Nano RX we condense 2 years of engineering experience, listening to our customer requirements, and pushing ourselves to the maximum (or in this case, the minimum!). The end result is a full range receiver, at the smallest size of any receiver in the industry (yes, it's smaller than the XM+).
