RE: First Glider
The Dream starter package is not a good choice. Those servos are WAY too big. They weigh about 1.6 ounces each and you want servos that weigh about .3 to .6 ounces each.
The receiver is pretty big too, but tollerable. It weighs about 1.2 ounces where I would use a receiver of less than .5 ozs.
I would recommend the RTF. It will have the right stuff and will get you into the air fast. If you find you like the hobby, then you will want a computer radio which is not what the dream starter offers.
Besides, the radio that comes with he Easy Star can fly any 3 channel glider or any other 3 channel small electric plane.
