I did try to unset the kill_throttle value automatically as soon as the first condition block hits (it's a nitro engine, so at least I have the safety of knowing that it has to be started first before I'm in danger of losing a finger). Unfortunately, this was not enough to make it work - the throttle control still is stuck at 0% until you click the "launch" button. So, I'm having to connect serial for the moment, click launch, switch to manual, start the engine, fly it up, and then switch over to auto2 which is then ready to take over. Was hoping that there would be a simpler way to do this, but I can see why it doesn't exist in a plainly-accessible way. :) Thanks,

I believe you can set conditions, such that when ground speed > X m/s, it will unset the kill_throttle variable (<set value="0" var="kill_throttle"/>) and deroute to a different block.  This would allow you to "activate" the throttle by running with it, or just taking off in manual.  I did a quick search for examples in the flight plans, but couldn't find anything.
Or you could just take out the part of the flight plan that is setting the kill_throttle variable.  But make sure you keep safety in mind.  You don't know how much you love your fingers until one of them gets chopped off.

I finally figured out my throttle problem, and everything is now tweaked
and
seems to be running perfectly. However, I'm trying to fly without using
the
datalink radios, and while I've been successful so far, there's one thing
that I need to get around - the need to click the launch button.

Is there a simple way that I can add an "auto launch" to get the throttle
going in my waypoint file, or perhaps trigger the launch command from the
radio or similar? I could theoretically employ the "gear" channel, though
I'd rather just be able to add it to a waypoint. Since there exists a
"kill
throttle" variable, isn't there something I can add that automatically
acts
as if I've clicked the launch button? Thanks,
-Adrian
