The larger one is to use if you have a three wire charging port that will accept that binding plug - might keep you from having to remove the Rx from your plane.
If the radio that you have is the 4 channel version here is a place for more info. - but since you seem to have a manual, it must be the 6 or 9 channel version - then this link is of no use to you.
However, you may have the 6 channel Rx that is sent with the 4 ch. Tx - then you could get some info for the Rx - just ignore the Tx info.

Thank you for the information. I have a Turborix 6ch radio and several RXs that I plan to use in several helis. I am new to this 2.4 gear. The manual I have is not the best.
