ArduPilot Legacy - RTL & Loiter FPV Video
Posted on October 9, 2011 at 1:30pm 4 Comments 2 Likes
A couple flights this morning using my trusty old ArduPilot Legacy & ArduIMU. Separate Mediatek GPS's on both AP and the Remzibi OSD. A Hobbyking 420 TVL camera provides the video sent back to the ground via a BOB Fox 700 1.2GHz transmitter. FPV is done with video goggles. Radio is a Hitec Aurora…

Sounds good, price good, specs good but not much interaction from the designer, who doesn't seem to correspond well.
Actually I'm not even sure it is legitimate, correct me if I'm wrong?

Edit: Added plane photo's below.
I'm still using the original ArduPilot v2.7.1 & thermopiles mainly because I have them, don't like throwing anything away and they work pretty darn well now that they're setup properly after many, many test flights! I've also recently got my FPV (First Person View flying)…

Android Phone Center of Gravity Calculator.
Here is a free Android Phone CGC (Center of Gravity Calculator) for planes.
It will calculate the position of the center of gravity of an airplane
using the tip chord, root chord, sweep and required CG in percent,
measured back from the leading edge at wing root.
It's free,… Continue

viky said… - have u got success in reversing ur aileron ... i m using same setup with XY sensors

viky said…
- i think i can correct it but want a clear view ur ailerons r reversed in automode or manual mode. If its auto change is to be done in the code else it has to be reversed using RC remote... let me know whats exactly it is

- so u must have tried #define ROLL_REVERSE 1 , then nothing happened ... am i right..

viky said…
- actually the same problem i had faced but my elevator movement was reversed
in autopilot so i tried to correct it by #define PITCH_REVERSE
but nothing happened later i found thaT this header is not at all used inside code so i just follow the logic in code and got the line to reverse the motion of either aileron or elevator in ... void pulse_servos(int roll, int pitch) //Normal mode
{
pulse_servo_1(90+roll);
pulse_servo_2(90-pitch); //invert sign if you want to reverse the servo...
}
This is what i had changed then to work it well.
so
I did few tests and got semi success in few , hopefully i can make it this time atleast 80% success with little changes in trim as u recommended in ur blog failure and success.
Its very nice blog i will try to write the one ... it really helps ourselves and others

Cronselaar said… - Hi, this must sound stupid, but how do you get the nice line logs in GE... My current position just constantly changes. I'm using a E406. I can't seem to get the right altitude data in the GS2 either.. Any help would be appreciated.

bruno voisin said… Hi Graham, this is Bruno from Cape Town.
These are my first steps in the UAV world, and I am interested in building a ArduCopter to conduct game counts in a nature reserve. Any advice / recommendation would be most appreciated.
Thanks in advance,

Robert Dielenberg said… Hi Graham,
we're developing a UAV here in Newcastle, Australia. We've been experimenting with the ardupilot 2_7_1 for a few months. Having huge problems with altitude hold and throttle. We're using a petrol engine. We realize the original ardu is for electric. It seems there is not much data on petrol engines for ardu. We had a crash last week and lost the plane. We're going to rebuild the code from scratch and simplify it. Will get back on to you on our progress. Cheers,
