The 350QX has 5 modes :

3 Video mode, purple led

4 Agility (acro) mode Solid red led

5 RTH blinking red led

This File adds a 6th mode Combining Stability mode , with Agility mode kicking in whenever right stick is moved past 90% (adjustable) in any direction. This allows stunts (Flips and rolls) while letting go of the sticks will allow the craft to self level.

This setup has modes controlled by S-A , SE and SB switches.

SA up =  smart mode

SA dn =  RTH

SA mid - enables SB

SA up and SA dn over rides SB so I can quickly switch to Smart or RTH.

SB up = Stability mode

SB mid =  video mode

SB dn =  Agility mode

SE dn & SB up = the new Stagility mode
