"Hi,
the best way is to check their website, some values correspond to the motor size
and one thing - Kv is rotations per volt
more details you can get from: http://en.wikipedia.org/wiki/Brushless_DC_electric_motor"

HelloIm thinking on getting a set of four eflite park 400 brushless motors that are 890 kilo volts. My goal is to lift a bit more weight.Whats a good formula or source to measure the rpms per kv? and…Continue

Diego replied to Diego's discussion rpm/kv calculations"I Like it. It has so much information. on the motor readings, for example Turnigy b2835-06 (5100) how can I translate or undestand what the value of "b2835-06 (5100)" means??
Thank you"
Sanbernar replied to Diego's discussion rpm/kv calculations"Hi Diego,
try this calc
http://www.ecalc.ch/xcoptercalc_e.htm
it is quite useful.

HelloIm thinking on getting a set of four eflite park 400 brushless motors that are 890 kilo volts. My goal is to lift a bit more weight.Whats a good formula or source to measure the rpms per kv? and what type of changes on the PID values would someone suggest? also I have a set of four 40 amps ESCs.Im waiting on somo other motors that are 1025 kvs and im guessing the rpsm are gonna be too high!!! and might make the yaw and stabilization go crazy.Any good websites or forums that might help…See More

"when you turn the quad on its side, or front, the -999 should move to ax and ay"
DeveloperMichael Oborne replied to Diego's discussion Odd accelerometer behavior
"have you done the cli tests for imu?"
Diego replied to Diego's discussion Odd accelerometer behavior"I figured that means Z axis.
What could be the problem... I pretty sure I have all props, esc and PDB properly attached, X mode set and APM leveled...
When I do hand test, if quad is leveled, it seems to want to stay there...…"
DeveloperMichael Oborne replied to Diego's discussion Odd accelerometer behavior
"az is gravity, and -999 is normal"

Hi. When i do a hand test by holding the quad, if I tilt left.... i feel the quad wanting to level, if i tilt right.. i feel the same... when i tilt back it the two front motors spin harder wanting the quad to flip.. same thing when i go forward... this has happened the whole time.. All props are ok, esc properly connect and calibrated... I think the accelerometers are bad... i have a picture after i level the APM.. i get this... all the time. initially diydrones shipped a bad PPM board ( with…See More
Diego replied to Diego's discussion Odd accelerometer behavior"
what does the AZ means?? it is always on -999

Diego replied to Diego's discussion Odd accelerometer behavior"Did that and... but it reverse the left and right...hehhe"

Hi there. Im back. I have been trying to lift my quad with no luck. All props are installed OK, wen in CLI, i run setup/motors and they all do the right thing when the elevator stick is up, down, left, right.

Diego replied to Dane's discussion Arducopter 2.0.38 quad always wants to flip"so what was the problrm with your big quad? wy was it flipping?"
Diego replied to Sasha's discussion When switch alt_hold or loiter...its gets higher in sky (Stab mode ok) no sonars. (mag+gps)"Hello Jason..
any good tip on how to test motors and ESC??
thnx"
Diego replied to Dane's discussion Arducopter 2.0.38 quad always wants to flip"Did you ever solved this issue?? I love the vids, your dog reminds me of mine. Since your quad hovered for a bit, all motors and props are connected.
Did you ever figured the problem?"
