I've been told RTR is not ready to run but ready to re-assemble ! Hey Nankin ! I got my Radio issue figured out on the T-Rex. I did need to enable the gyro , then enabled the triple rate switch. The gyro is strange, when the Tx is set for GY , its in standard mode on the gyro. When the Tx is in STD mode the gyro goes into head holding. I also needed to up the settings a little for the gyro , went from 50% stock setting to 75% , seems to hover good now.
