First things first: documentation
Helicopters are technical toys, and your first source of reference (before this piece of text, anyway) is the official documentation. You should systematically consult the official documentation before applying any tip you read, or watch, or hear from anybody. Don’t trust anyone, because people says whatever to look smart. This includes me, of course.
I’m writing here the documentation that applies with my own configuration. You may have a different set-up, most probably the transmitter and the FBL gyroscope and governor, because those two are not included in the T-Rex 300x Combo kit:
- The T-Rex 300x User Manual:
- The FBL gyroscope / governor user’s manual:
- The servo user’s manual:
- The ESC user’s manual
- The engine user’s manual:
- The receiver user’s manual:
