RE: jr ergo 30
What gyro? What motor? - probably two items that are just as important or even more important then the heli.
I certainly agree with Rafael23cc - the Ergo 30 is now considered more of a "museum" heli, parts will be difficult to find. And when you are beginning, they become very important very quickly.
I see you are from Canada, Heck you can get a new 30 size heli in the great little Century Hawk Pro (much better then either the Ergo or Venture in their day) along with and OS37H engine in Canada for $370.00 Canadian dollars.
Those with an Ergo already would probably be willing to by a used airframe for about $100.00 as a "parts supply". So, unless the motor is a current OS (e.g. 32SXH or 37FXH) and the gyro a current Futaba (GY401) or JR equivalent, to make the $200.00 remaining worth it...I would stay away.
