Hi All,I was recently fiddling around the code for a while and decided to create a tutorial out of it so that others may find it useful. If I would have known this knowledge long back, I am sure I…Continue

What have people found to be the most efficient forward speed for mapping on a 3DR Y6?

Comment by agentremnant on December 16, 2014 at 2:46pm

Please stop the misinformation.

2200kv with a 6s will kill a 30a/40a ESC.Also, weight of quad impacts flight time..... Slower KV larger propellers is more efficient. Battery capacity influences flight time and somehow you estimate flight time without this variable..... So please just stop. 

Please use a calculator sch as http://www.ecalc.ch/

Battery voltage, KV, Propeller size are all contributing factors. Voltage can be anywhere from 3 - 50v. 

2200kv..... I would never recommend this speed of motor on multirotor unless using 2S.... But your discharge requirements on the LIPO are going to severely  limit thrust.

Comment by Tony Hyde on December 16, 2014 at 2:30pm

2200kv @ 30A will but it depends on the motor and props for lift..
2200kv is usually a small profile motor for about a max of 8 inch props and at that wattage 2 or 3 cell you are looking around sort of 15 mins flight time on a quad or tri.

Question about pixhawk hardware:

pixhawk logs vcc @ 5.13v, however its servo rail voltage measures 4.41v. I use 6s lipo, so I have a non 3DR power module and at first I though that the problem was with its BEC sagging under load, so I disconnected it and measured voltage without load exactly 5.13v (as pixhawk logs) When I connect a 9W LED, voltage goes up to 5.2v so this is definitely not a PM issue. Is there some kind of a diode between the main vcc and the servo rail?

I hear ya man, don't sweat it.  Now let's go fly! :)

@Josh and @David

I apologize for the comment I made earlier, I'm venting because there are folks out there who think they know what's best for me and others.  I do see a benefit for having it, but I don't want it forced on me unless I break the 400' ceiling.

I actually live inside two circles haha

I live within one of the circles... The dotted lines in the sky are quite annoying. But seriously, I share your pain.

Comment by Doug Walmsley on November 26, 2014 at 6:50pm

My issue is with the display.  I can barley see the map due to the TFR circle over my property.  I'm not saying to rid it, but I'm allowed to fly withing the TFR as long as I do not break the 400' ceiling.  Therefore, I should have the right to turn off the TFR circles if needed.  Since I'm sure you don't live within one of these circles, it's easy for you to stomp your feet and be vocal for something that doesn't affect you.
