Folks, can anyone clarify how the third serve on a 7.1 is controlled?
Marked as poison 5 in the servo ports & the instructions say it’s a 360 degree periscope function.
I cannot find the method of activation for it from the transmitter.
I want to use it as the slew control in the Ferdinand rather that a boogie knock up of a rotation or elevation unit!
Any advice greatly appreciated

The trim lever underneath the right hand stick. The standard HL 7.0 transmitter doesn't have the sliding trim. You have to have the 7.1 transmitter which has the working trim slider.

"Marked as poison 5 in the servo ports." A little help from spell-checker, eh Bix? (Yeesh, I am rascally this evening.)
