That's awesome buddy! Nice collection! I don't know anything about the 3GX but there are many people here that are very knowledgeable about that gyro. I'm sure someone will be around to help answer your questions. Find the "600 Sized Heli's" section of the forum. That's were all the 550 talk goes, too. If you are looking for help, specifically, on the 3GX, there is a "Gyro" section there. If you have general questions, you can post them in the Beginners Help section.
