Now we are talking my language!!!
Set the total throw of the master throttle (3) to correct travel.
Put the second throttle servo on channel 8......or whatever, but that is what I did.
Go to mix number 6 or 7 as they have an expo function.
Using the expo function, map the response of the second engine to the response of the first. If you cannot get enough throw, you can change it using the ATV'S. This really helps with throttle up. Make sure the engines are adjusted as normal for flight.
Go to the basic (aero) and aux channel. Set channel 8 (My choice) to vr-8. This allows independent idle adjustment of the second engine. Remember which one you use!!! The second engine can be adjusted for idle, but as below, the link function ties the trim tab to both channels.
Turn on link function. This attaches the trim tab to both channels.
Rudder mix on top of this.
Use mix number 1 and set rudder as master and channel 3 as slave.
Set swtch to stk- throttle
Set position to 40% or more.
Use mix number 2 and set rudder as master and channel 8 ( Or whatever, but nine) as slave.
Set switch stk- thr
Set position 40% or more. Note, this setting must match the setting in mix number 1. I used 42% for both.
The importance of the above mix is that the rudder does not command the engines to cycle up and down during taxi. This can be very dangerous. The throttle must be 40% or more for the mix to activate.
I have not messed with the kill function yet, just use the trim tab.
You will love inverted flat spins. To get out, reverse the rudder and so the thrust. Knife edge is also easier.
Good luck,
