9chp change mode Qns

[rba]

Yo bros...Newbie here. I've just changed the 9chp from mode 1 to mode 2 by swapping the spring and lever. And I had changed the tx setting to mode 2 by presssing mode and end while switching on the tx power and changing it to 2 using the dial.

1) Any other setting that I need to change?
2) What type of grease that is used for the moving parts of the tx? Where to buy cheap cheap good good?

Thank you.
