am doing a vtol project with apm 2.8 autopilot.
am thinking of uploading the quadcopter code into the autopilot and getting it to fly vertically up.
once it has gained some altitude , i would be turning the motors using an external servo. what all problems should i be concerned with while doing this and please help me with some suggestions in solving them.
Consider me shocked by everything I got with the Hawkeye Firefly 6s! I bought it because it was an inexpensive 4k action camera that has great video quality and decent audio, but got way more than that. Having seen many videos using this little camera, I expected good quality footage...and that hasn't let me down. On top of that, it comes with a boat load of accessories. In my opinion, if you don't want to spend the money to get a GoPro (which is still the best image quality in my opinion) or a Yi, then this is the camera to get.
I have recently purchased Skylark Tiny OSD III with SW 3.0 Firmware update and after few flights. I am having problem with my osd information after when I turn on my OSD I can only see video without OSD Information. After If I press reset button or I unplug the RSSI with 5v connection lead and plug back in the OSD information comes back again not finish yet.After all connection with OSD information seems ok then I throttle up with motor the OSD information goes off.
Similar method to bring back the OSD information. but no OSD information in the end.
I am still unable to solve this problem. A blink of an eye the OSD information gone.
Please help me if anybody having the same issue and solved it.

She died Saturday.....but I learned something about the limits of foam board.....I flew her successfully a few times, but on the last flight, I turned to make a high speed pass over the runway and when I leveled the wings and throttled up, I saw the fin buckle and turn almost sideways......she broke in half when she hit the ground..BUT, I learned that the tall slender (unreinforced) tail fin was just that...too tall and too slender....I've already addressed that problem..the fin failed diagonally from lower back to mid front. I've decreased the slenderness of the fin, and will add stiffeners, probably bamboo, to both the leading and trailing edges for their entire length. Kinda sorta reminded me of what paper does when you blow on it edge on.

We have recently developed and tested a formation control algorithm for fixed-wings in Paparazzi. The position of an arbitrary number of vehicles can be controlled in a circular path. In fact, we are not restricting ourselves to circles but to any closed orbit, such as ellipses, thanks to the guidance vector field that guides the planes.
The algorithm is under more tests, but it should be soon available for the general public. It is quite easy to employ, the user has to declare only the IDs of the planes, the communication topology (neighbors' relationships) and the desired inter-angles.
In the following video the planes exchange positions every second. Delays, out-of-date positions (GPS delays), packet losses, etc are expected to be (and actually they are) present. It is quite interesting to remark how robust the algorithm is. According to our calculations the impact of such nasty things are not very important (ofc up to a certain point) for the convergence of the algorithm.
The work will be submitted to the next IROS conference. Once the paper is ready, I will also post it here just in case somebody is curious about the details.
