My sources tell me that EXperts are JR. They use JR aftermarket arms. I have many of them and are as reliable as futaba or JR. Their standard hitorque is only $17.99 and pushes over 60 ounces. They aren't really that fast, but accept 6V NIMH well and you get more speed and torgue with the voltage increase. Thier mid sized servo is super on fun flies and small 3D planes and put out more than 50 ounces. I highly recommend them to everyone. I stripped some gears by banging large surfaces when loading or unloading and gear sets were only $5.95 for two sets of gears. If the specs work for you, try a couple out, you won't regret it.
