"Thanks a lot. That's just what I needed. Happy flying and thanks again :-)"

"Thanks a bunch. I don't know why it did not come with the quad. So be it. If I may ask also, what settings are you using for the ESC?"

"Long time, I am curious as to how you ended up setting up your ESC. I screwed the setup on one and need to set it up again. Let me know."

"I have the jDrones 10 Amp, it says jDrones AC20-1.0, Programmable ESC, BEC: 2A/5V, DC: 6V-16V."

"I badly need the manual for the ESC. I have screwed one up and there was no manual with my quad from JDrones. Can anyone e-mail it to me ay mikey_hd@yahoo.com or fax it to me at 5617531901. Thanks a bunch."

"Jani, the quad flies pretty good for once. It is finally a good day in West Palm Beach. I am gathering all of my problems stemmed from the one ESC not calibrating correctly, heavy sigh. I was flying it with 8" props and I haven't changed…"

"Jani, thanks. I will try those settings tonight. As I said, I did get the ESC to calibrate but I accidentally turned off the brake setting. What are the settings of the ESC's so I can turn it back on. Also, I came across some 8" props. It…"

"Mikey, have you changed any of your PID settings? You could try following PID settings on your stabilize modes.   P: 2.3 - 2.4I : 0.015INT: 40   Few people has reported that these will make ArduCopter with bigger motors a lot more stable…"

"Thanks Sam for the thoughts. I decided to calibrate all of the ESC's manually. One of the roll ESC's would not calibrate. It would not give the correct tones. I did the other three and came back to that one and it calibrated correctly that…"

"I dont know if thats normal behavior. But, you could try the following. Does the roll related propellers throw air downwards? You could also try recalibrating the roll related ESC's manually as described in the second ESC calibration…"

"Well, it looks about right, according to jason, those nombers means degrees * 100, so that means that on your first test, the IMU was reading from -.57 degrees to .38 degrees, which in my opinion is fairly acceptable for a non-moving quad. The…"

"OK, I just finished doing the hand test. Whoa, that was exciting. The forward backward pitch, I could hear the motors fighting my change. The yaw CCW and CW I could feel the motors fighting back. Doing the roll left and right I did not feel too much…"

"OK, I ran level and got IMU Gyro offsets: -8.31, -5.00, 14.00 Accel offsets: 8.14, -9.03, -7.30 I ran the IMU test again. The numbers change incrementally by a few digits at a time. Col 1 goes from -8 to -57 then back down to 0 then to +38 and back…"

"Thanks. I will look into that tonight. I use a 6' USB cable so it sits on the floor flat all the time but I will pay attention to what you say. I will let you all know what happens. Thanks again."

"#4 When you power on quad the IMU test is run. That's when you need to hold it still, not when loading code. The imu test is pitch, roll, and yaw in degrees * 100. When the quad is on the table, you should see low values that are pretty…"

"Thanks for the reply. When I can today, I will do the level command and check the IMU again just to verify the output data. I am not familiar with the hand test. I would think that it is done with a little throttle with no props, correct?"
