You have to be ABSOLUTELY SURE every single control surface is moving the right direction and in proper trim before you fly, every time you switch.
Do it often....you will screw up and take a plane out, pretty much guaranteed..
So each plane has a label on it where you connect the battery. You ALWAYS (don't you?) do a Tx Rx systems check before takeoff?
You also set up the surfaces mechanically to be neutral and if Tx trim is needed on any plane, that information is on the label. Just be systematic and run a checklist like any "proper" TM
Certainly fitting switches instead of having to have a laptop computer on the field is quicker and easier. Also cheaper. It does require an ability to solder. Switches about a dollar each.
The Turnigy 9x, it is now V2 so there has been something done to its menus etc. It is still twice the price of the HK T6.
