Technical Data
No Onboard BEC. Requires External U-BEC (Battery Eliminating Circuit)
What does that mean? An extra power source for your receiver is required. The use of a UBEC, a voltage regulator, or extra batteries as the power source for your receiver is required for this version. If you hear the music tone repeat again and again for more than 3 times, you may need to check your power source to the receiver.
