hello all , so i just finished my second disco build , but with a few differences , i wanted to get as many bells and whistles as i could so ive swapped out the naza for APM 2.6 and minimosd , all the video gear and gimbal going perfect , but when it came to tuning the PIDS things get hairy , im using all stock TBS 900kv motors and the "bullet proof" 30 amp esc , i see a few of you guys had the original disco set up running apm , could you share your pids? so i can compare notes :D any suggestions would be awesome ! :D

  • Hi guys,

    I am new to this and i have just bought a TBS pro, i have a APM 2.6 and a uBlox GPS with compass, Futaba 14 sg RC, i have a skyzone fpv goggle with 2 axis head tracker and a 2 axis FPV camera, a GoPro 3+ BE, a long range VTx, would like to know how to connect all these especially power the Gimal servos and the FPV camera, APM 2.6 can't power servos. Would appreciate anypne can help me, tks

  • ok so about an hour ago i had my final crash with my apm 2.6 on the disco pro , after many sessions of tweaking and tuning it flys but nowhere near as well as the naza , im sure its just me and my inability to tune my pids correctly , but i have inflicted enough damage to my poor wee disco , so im going BACK to naza, anyone in nz want to buy a apm2.6 and minimosd? i did however find out that most of the crashes ive had only damage the gimbal , ive broken off the plugs on the top plate and had to solder them back on , popped out the rubbers and just slightly bent the top corner where the gimbal bolts into the frame so as i learn to fly better im going to look at adding pool noodles around the gimbal so i dont break anything else

  • Hi,

    Here pics of my Team Black Sheep discovery pro.

    Can any one shed some light on tuning yaw for both acro and stab modes.  Its something i have never done but with the stabilized gimbal its one of the problems im seeing when filming the flight.

    Regards,

    Tony

  • finished build , just needs nav lights and a bit of a polish the GPS case is an old portable speaker with the guts pulled out on a foam noodle , and a plate of copper behind i now get a compass mot of 9% with all my gear going , so telemetry at 900mhz control at 433mhz and a 2.4ghz video tx gps and throttle at 100% im pretty happy with that :) what do you guys think??

  • Probably. Latest MP is 1.2.80
  • 3692849183?profile=originalok so today ive been having another go, but ive noticed a few diffrences  between my mission planner pids and everyone elses , i seem to have larger numbers than everyone else , and if i try anyone elses pids its its just a mess of wobbles here is a picture , that p rate is about the highest i can go with out ossilations, so if i was to use  euans for instance i get to about 5% throt before it gets the wobbles and experientially gets worse unless i kill throt

  • I can share my PID's if you want, but they'll not be spot on, given the extra weight and CoG issues of the Pro model.

    I'm also an advocate of the "less is more" school, so I'm running standard settings, with only 2 changes:

    P on roll and pitch=0.145, I=0, D=0.008

    Yaw= 0.225 (though if you're gimballing, you might want to go *less* not *more*)

     

    My build was here:

    Gotta say...I do like the Pro version. Lots of feature I hope will trickle down to the normal disco.

    Your picture shows an old style GPS, but you say you have got APM2.6. APM2.6 comes with no onboard compass.

    If you have an external compass elsewhere on the frame, keep it far away from any magnetic fields or anything that is metallic. If you don't have a compass, get one. you can find them from a few places like here or ebay or hobbyking.

    Keep the compass and GPS away from any transmitters like your vid tx and the telemetry radio.
