A stable tune will return to level in stabilize when you jerk the stick suddenly in roll or pitch.
I start with a Stab_P of something conservative like the default 4.5.
Then a conservative Rate_D of .005
Try a rate_P of .1 and increase to…"
I spent some time with Leonard last week testing and reviewing Auto-tune. What I learned was Auto-tune won't crash your copter if you start with a stable tune, but it will crash a copter that isn't properly spec'd.
"Leonard's frame is 3d printed.
There were two bad crashes. a 550 heli didn't have redundant power and looks like the BEC browned out keeping up with the servos killing power to the pixhawk. It flew an amazing first run. It crashed in…"
"It looks like you've added wings which will create lift and other unwanted aerodynamic effects. Look at umbrellas that are made for high winds. They let the air flow through them with special flaps to prevent big pressure deltas. I'll bet…"
All you need to do is connect a 3DR Radio module to the BT module like Chris has shown above. Power it with 5V and you're done. I use a Lipo and cheap BEC from HK.
I have this embedded in my RC and use it all the time!
jasonshort - thanks for sharing your experience. I have added lenses to the flip externally and they work ok, would you mind sharing your lens adaptation for the flip? I have been researching the ardupilot and trying to understand how it might work with our twin easystar - maybe I should just jump in and get it. thanks again for your thoughts.
Hey man wondering if you have flight tested your AIR app yet. Would love to get my hands on the source - even just the artwork, it looks amazing. Great to have another Flash dev on here to toss ideas too.
I saw a post concerning rc cars. Well, that's what I want to do but I now understand that this is more complicated than I thought due to the fact that cars move slowly and the GPS has a hard time with that. I understand that one needs other sensors like magnetometers, obstacle sensors and etc. I was wondering if you have seen a post where some nice person has listed the components used and the codes. I was kind of excited to do this but I'm starting to think that the only way would be to have someone who understands it to build it for me or walk me through it. I was thinking that an arduino controller would connect to the ardupilot and the ardupilot would connect to the RC.
I thought I would ask you if you had any suggestions on this.
Sorry I don't. I would Start with the encoder for the wheels. These usually use a hall effect sensor and a tiny magnet attached to the wheel or other rotating part. Maybe that is a hint that could lead you to some example projects.
Great to see the work in progress. I have a new APM that I bought ready assembled and programmed few months back, it was a little too unstable for my Flying Camera Mount designs that I am working on. However I have just uploaded the latest code and will be soon giving it another try. My normal test FC is a KK Minso Kim board that has no bells and whistles so I always have a benchmark to test and evaluate the aerodynamics. I then fit a MK board with the full kit. I am desperate to get away from MK and hopefully your code will be the answer. The thing that I thought might interest you is the fact that my MK boards are modified to take 67 deg/sec Gyros as I need to cage the models movements to stay within the 20 deg/sec that the camera mount uses. It is of course a bit risky if the mk gyros saturate as that would lead to a crash but I keep the stick inputs to a very low limit. The fast response and low noise seems to be the key to great stabilisation, plus the fact that the arms are 1 meter across with highly responsive motor/prop combination. The thought occurred that maybe we could develop a super stable version of AMP just for Aerial Video. The 500 deg /sec gyro does have amplified signal at 110 deg/sec but I expect that it will amplify the noise as well.
