"What's your thrust to weight ratio? First have to determine if you have an over or underpowered quad."

Justin replied to yugo's discussion Where To Buy Pixhawk
"There are others even better due to smaller form factor. Pixracer and Pixfalcon I believe are two."

Hi Gents,I am writing this to get your feedback. Like many of you I am using OPTO Esc's in my build. I am powering the Pixhawk from the 3dr power module and in the past I powered the servo rail by a bec attached to my PDB. With this new build I am…

Justin replied to ActionDrone's discussion Pixhawk Copter "Bad Accel Health" in PIXHAWK
"I setup 3 Pixhawk's indoor. All three were working great but eventually one started receiving the same message as yours. Turned out to be a hardware issue. The only real way to determine that is by a process of elimination and it sounds like you…"

Justin replied to James tate's discussion Totally Disgusted with 3DR
"I am equally as disgusted! I own 3 Pixhawks and frequently need parts. Im always needing buzzers, arming buttons, cables BUT I have also needed GPS units, telemetry radios, and others. Love the fact they always warned us against buying generic parts…"

Justin left a comment on PIXHAWK
"I also have multiple Pixhawks and each have their unique issues. At one time I setup 2 Pixhawk copters, both identical builds, PIDs the same, and they behaved differently. Even with identical GPS/Compass's, one got a GPS lock immediately, the other…"

Justin commented on matucha123's blog post Dangerous close-up with aircraft braking rules
"At the beaches in Los Angeles(Venice, Marina Del Rey, Santa Monica) it's not so much the small aircraft BUT it's always the police & tour helicopters that fly way too low! This has become a common occurance!"

Guys I am desperately seeking your help! I have two Pixhawks with the same problem. When my quads take off and reach a low altitude hover, they both flip over and crash! This behavior was only occurring in one but now both!I'm sure you will want to…

Justin replied to Ben Thomas's discussion I've tried everything on here but it still wobbles and flips on takeoff.
"I know this is a very old thread but I am having the very same problems as the gentleman who started this! Exactly! The throttle increasing on its own and the precise flipping. Mine is a larger and much more powerful quad, but same behaviors! I…"

Justin replied to James tate's discussion Sonar on Pixhawk in PIXHAWK
"Yes sir! I installed the max sonar 3dr sells. Just make sure you're installing it for the right reasons. Will it serve a purpose or is it for the "cool factor."
Make sure you use a shielded cable! You may have to build one yourself! Regardless, good…"

Justin commented on Randy's blog post Copter-3.3 released!
"@Randy, dealing with odd situation.  Have 3 Pixhawks and can not connect to MP in flight data screen.  Parameters get stuck loading BUT I can connect in initial setup or config-tuning.  Same issue on all 3!  Any ideas?"

Justin replied to Dale Greer's discussion Would a Pixhawk be able to run a tilted rotor hexacopter, like CyPhy LVL 1? in PIXHAWK
"Out of curiosity, what sparked your interest in a tilted hex? When a multicopter is in forward motion, they tend to pitch down and can screw up video/photo(I get that) Tilted motors are able to compensate for that but in the multi you're looking at,…"
