"@Marooned, you use the inlcuded mount with the hole that came with the motor, and then that attaches to this mount. Hopefully you saved those parts that came in the bag with every motor."

Flashing 3DR ESCs or RC timer ESCs with MUCH better firmware
Started this discussion. Last reply by Vernon Barry May 21. 6 Replies 0 Likes
Ok, so here's the basic deal. The stock firmware coming on the ESCs works as intended but is far less than ideal for use in our quads. The problem here is that due to startup sequence timing from…Continue

Vernon Barry replied to etienne.t.micallef's discussion hexa copter calibration problem"Sorry, I wish it were easier to flash the ESCs but honestly, it works so much better.
Again, if you follow the manual calibration of each ESC using either a servo tester (another handy too to have) or just the radio and receiver, then you will get…"
Vernon Barry replied to etienne.t.micallef's discussion hexa copter calibration problem"No, the APM is working as expected. Your ESCs are not working as expected due to calibration being off. As I have described this is a common occurence because the stock ESC firmware always wants to calibrate every time it first has power applied.…"
Vernon Barry commented on etienne.t.micallef's status"Again, i have seen this too with APM 2.0 and the stock ESC firmwares. Disconnecting and reconnecting the battery a couple of times got everything "in sync".
The problem is the stock ESCs have the programming mode at bootup. The APM is…"
Vernon Barry replied to etienne.t.micallef's discussion hexa copter calibration problem"I think I described it to you.
I have seen using the stock firmware on the ESCs with APM2.0 the ESC didn't catch the bootup sequence and sometime either don't respond at all, or worse, some work and some don't. The fix is to…"
Vernon Barry replied to etienne.t.micallef's discussion hexa copter calibration problem"The APM update rate for the ESCs is higher than what a servo can take. Thus this is normal, you cannot test with a servo."
Vernon Barry replied to Lewis W's discussion Explanation of log data please!"I'm going on a limb here but you get that the GPS has a processor and then the APM is an entirely different processor? They talk one way only, so the APM caputures the data when it's ready within it's main loop, and further, writes…"
Vernon Barry replied to Brad Smith's discussion What do you think the APM should do on fail safe"This is just my opinion and thus take it on face value, I would not and will not fly with a 9x.

Vernon Barry replied to Lewis W's discussion Explanation of log data please!"It's known the logs are only good for maybe 3.5-4 hours based on the size of the high speed data card inlcuded. Normal flash isn't fast enough, thus why it's a special card.
Next, the logs are information from the sensors, so the GPS…"

Vernon Barry commented on Monroe's blog post Hobby ESC as a AC Servo controller?"What you are effectively talking about is taking a BLDC motor and controller and using it in step mode, AKA stepper driver.

James Dinh said… Hi Vernon,
I have APM 2. Everything worked great, flying great. Then, I had a crash. My fault, not the board. I crashed into a tree. Now, the board lights up fine when I plug it in via USB to my computer. All the LED lights show normal function. I get GPS lock, I can access Mission Planner, erase eeprom, load new codes (2.5.5), etc.
With the USB still in, if I plug in the lipo and arm the motors, I can throttle up and the motors spin normally. But as soon as I unplug the USB (lipo is still plugged in) the board goes dark and I get no response from the motors other then the dreaded continual beeps. Somehow, it seems that I'm not able to power the board via the output pins (jumper is in on the JP1 pin), but can power the board via USB.
I've checked all the soldering on all my wires going in and out of the PDB. I've visually checked the board itself. All the soldering looks good. I guess there are many things that could have damaged the board during the crash, but why does it work normally as described above? Any ideas or suggestions would be much appreciated. I miss my robot friend. :(

James,
Make sure your jumper is still present.
I had something similar happen to me.
I thought it was the jumper but ended up being the diode (D1).
What I discovered is that D1 burned up on me.
Dont know how or why.
D1 is nearly impossible to replace as it sits just below the jumper.
What I ended up doing was soldering a wire from VCC to +5V.
Basically bipassing the diode.Hope this helps.
Contests
Season Two of the Trust Time Trial (T3) Contest has now begun. The third round was a reliablilty/aerial photography round for both planes and copters, which is now closed. Stay tuned for the next round, beginning soon.A list of all T3 contests is here.
