Okay, I got a Cockpit TX Saturday and so far I love it... my only complaint
was that I could not figure out how to set a launch preset... I emailed
Karlton and asked if it was possible which he replied that it was... I
emailed him back after playing with the TX and the manual for a while and
asked him how b/c I couldn't figure it out... I emailed him late lastnight,
so he hasn't had a chance to reply to me yet, but in the mean time I have
been mulling over it, and I think I have a solution if Karlton doesn't have
a simple answer...

Here is what I have come up with (only partially tested), please let me know
if you see fault in my logic/design:
As I see it there are two aspects that need setting for the launch: elevator
and rudder (although rudder only really for Tip Launch) so I will do this in
two parts...
1st the elevator)  I tried this one late lastnight and it works fine for and
elevator only preset:  The cockpit has three Mixes called throttle
compensation, spoiler compensation, and flap compensation; all of these
basically compensate the elevator setting for the speed changes caused by
the use of the corresponding control (throttle, spoilers, flaps).  Since my
ships are all rudder/elevator ships, so I chose to use the flaps switch (3
position) for my preset (if you use flaps, then you will have to use one of
the other controls and modify it in a similar way to the rudder below)...
Basically you set a percentage of compensation; when you flip the flaps
switch you can watch the elevator move to compensate, but since there are no
flaps the result is a preset elevator switch...

Now that was the easy part...

2nd the Rudder)  Here is where things get a little more complicated (at
least for me... I have not tried this yet, but don't see why it wouldn't
work)...  For this one you are going to use the "Combi" switch on the TX
which switches the Rudder/Aileron mixing in and out...  I plug my Rudder
Servo into the aileron position on the rx (like most people, I would
imagine), so the rudder stick isn't actually doing anything (now if you have
an aileron/elevator/rudder ship this won't work)...  Go in and set the
aileron/rudder mixing to say 100% (like I said I haven't done this yet as I
came up with it this morning at work), then go into the servo menu and set
the rudder servo's center to what ever you want the preset at...  Now when
you flip the combi switch, your rudder settings should force your aileron
servo (your real rudder) to the preset value...

Now these two setting are on different switches... now for the trip to Radio
shack to find a double pole switch that will fit on/in the TX and then
connect the wires in such a way that when you flip this new switch, it
effectively switches the combi switch and the flap switch (or what ever
control your are using) at the same time.
