Build APM 2.6 for data logger

Started by Vitalii S.. Last reply by Vitalii S. 3 hours ago. 5 Replies

Hi!I want to build small data logger for our plans. We want to use it on light gliders so every additional gram and mm has great importance. It should be really small, like 50*40*5 mm  or less ( I…Continue

Pay attention, sometimes motors have in their specs the thrust, but it's not lifting thrust but horizontal thrust (for planes)

??? I thought thrust was thrust.

motocalc works well for me.

Gjango, I don't know if you're familiar with this site : http://www.ecalc.ch/ 

The thrust depends on several factors : motor power, motor kv, propeller used. A 100w motor with 800kv and a 13" propeller will give you less thrust than a 300w motor with 800kv and a 13" prop, since the last one will be able to maitain higher rpms with such a "eavy" prop, but the motor will also be heavier.

hi to all

How can I calculate the thrust produced per motor in kg?

Comment by Ellison Chan on February 18, 2012 at 10:36pm

Well, 850kv @ 20amp would probably generate over 1kg thrust per motor.  So your flying weight with the gopro is over 4 kg?  That does seem like a heavy drone.  If you're really over 4kg, you should probably be looking at a hexa or octo.  Since if you try to find motors for a quad that can lift greater than 4kg, you're talking about expensive motors and escs.

Elison, 850kv with 20amp ESC. I just transferred from the normal jdrones ardu frame to the X1 frame. Should I change the motors and the ESC?

Comment by Ellison Chan on February 18, 2012 at 10:02pm

Adli, what kv motors come with that frame?  12x45 sounds like they're big for a 20amp rated motor..  Adding another battery in parallel will likely make the lifting ability worse, since there will be the extra weight of the battery added to what you say is an already heavy drone.

Comment by Adli Shahnaz on February 18, 2012 at 9:46pm

Hi guys,

Can I add an extra battery to the arducopter?What do I need to do in order to do that? Help please. Right now, I am using the JDrones X1 frame with 20amp of motor and 12 x 45 props. It seems  a little bit heavy to lift with gopro attached to it. Thanks.

Adli, is your camera fixed or it dangles?

Comment by Gage Halverson on January 29, 2012 at 5:55pm

I have the official 900Mhz telemetry kit soldered it myself I've tried using x-ctu and unbricking and reloading the firmware 

i called diydrones store and the lady didn't know what to do 

i found this posts and i kinda tried it (not soldering the wire on but just holding it therehttp://diydrones.com/forum/topics/xbee-900-kit-lights-but-no-telemetry?xg_source=activity&id=705844%3ATopic%3A645885&page=2#comments

Gage: You'll have to post info on your whole setup. If you're not using the official 900Mhz telemetry kit, I won't be able to help you. (I've never used anything else)
