Heading Lock Gyro & E-CCPM MixerTG-6100M is the so-called G-CCPM control board, which is combined with a heading lock gyro and an E-CCPM mixer. The heading lock gyro helps to control the tail, and the E-CCPM program makes it possible to fly the mini Titan E325 with a normal 4~6 channel radio. The normal flying mode and aerobatic mode are established in the program. If you are using a 4~5 channel radio, you can do the normal flying. If you are using a 6 channel radio, you can perform advanced aerobatic flying as well.
