TBS Caipirinha II auto takeoff with Arduplane: How to do it?

Here's a short video on how I did the Auto Take OFF on my TBS Caipirinha II using the Pixhawk lite with Arduplane 3.9.1 stable. This is executed using a mission, plane should be on AUTO mode to do it.

The same procedure is applicable on other air frames such as conventional air planes, v-tail, or t-tail. But the Take Off Pitch angle may need to be varied. For such air planes, I would recommend a lower pitch angle of 18 to 20 degrees.

RTL may be added as second command in mission, so your plane will immediately return to home location after reaching the desired altitude. Alternatively, a waypoint can be used if you intend to continue a full mission flight, or just switch off from AUTO mode to another flight mode like Stabilized or FBWA or Manual mode to take control.

It's quite worth noting that this mission is applicable in any location, since no waypoint is used. This implies that you do not need to upload new mission every time you want to use the auto take off. You will use the same mission. All you need to do is switch to AUTO mode then launch your plane. However, it requires to have a home point recorded prior to arming if you are to use RTL.

awesome! after i build my caipirinha 2 i will launch it like that. what fc with pitot are you using? Matek f405?

Great job! but I noticed that in the RTL command the altitude is 0. ??

Great video! Can you please share your param file? I am trying to figure out some good starting gains.

Thank you for sharing. Question, I’m building one myself and trying to figure out the arduplane setting to account for the flight controller being off center inside one of the wings. What are the parameters i need to adjust? Thanks in advance

Hi, I like your video !!, If you allow me, I have some questions:
are those vortices generators effective? To what extent and angles have you put them?

is it compulsary to use compass for rth auto takeoff??

I am planning my first plane to learn ardupilot, I have this answer, when you throw the plane, it goes to the waypoint in the middle of the launch? Wouldnt that be a little risky? Also, what do you mean by "it requires to have a home point recorded prior to arming if you are to use RTL", if I want to make autolaunch and then RTL, do I have to make a new mission for every launch and everywhere I go? Thanks anyway for the good informative video.

hi, what if i auto launch from different location from what i saved to the mission planner, will the auto take off will work or i need to strictly follow the mission planner location?thanks
