Title: Quad flight time question Post by: Tanmay.mathur on January 25, 2016, 08:11:16 PM Hi
here is config 4 x 2215 1000 kv chinese motors 30a esc kk2.1 frame weight 400 gm 1250 mah 3s 25c lipo auw = 900 gm how much flight time i Title: Re: Quad flight time question Post by: Tanmay.mathur on January 25, 2016, 08:12:40 PM How much flight time i could expect as hover time ?

Title: Re: Quad flight time question Post by: ad! on January 26, 2016, 09:19:38 AM what is the thrust produced ??
any spec sheet ? Title: Re: Quad flight time question Post by: satyagupta on January 26, 2016, 02:42:40 PM By the time you get in air the battery would hardly have enough power. Try to increase the capacity to atleast 3000mah+
Title: Re: Quad flight time question Post by: miginstruments on January 26, 2016, 06:51:07 PM Tanmay in my opinion you ll get a flight time of around 2.5 to 3 Mins. Use atleast 2200mah so that u ll get flight time of around 5 mins.
Title: Re: Quad flight time question Post by: Tanmay.mathur on January 26, 2016, 08:04:15 PM The motors are cheap chinese those yellow 1000kv the lipo is a 1250 mah 3s quadkopters.com lipo. 900 gm all up weight

Title: Re: Quad flight time question Post by: ad! on January 26, 2016, 08:08:50 PM 1250 is way to less...wont last a min or two.....1300mAh are usually prefferd for 250 quads
Go for atleast 2200mAh Title: Re: Quad flight time question Post by: Tanmay.mathur on January 26, 2016, 08:11:04 PM Could solar panels help ?

Title: Re: Quad flight time question Post by: ad! on January 26, 2016, 08:16:23 PM Solar cells wont produce such amount of current unless u have resources from NASA
add another 1250 lipo in parallel Also somehow even if u manage to get such amount of current from solarcells....the cells weight will anchor it to the ground Title: Re: Quad flight time question Post by: ad! on January 26, 2016, 10:20:11 PM hope this helps
Title: Re: Quad flight time question Post by: miginstruments on January 27, 2016, 12:44:42 AM at the cost of solar cells from nasa you can get a full truck load of batteries. so just get some bigger size battery like at least 2200mah
Title: Re: Post by: v2 eagle on January 28, 2016, 09:00:52 AM A 2200 mah can give you around 10mins of time and more if you reduce the weight to 700g. 900 is way too high. A 1200 can heat up unless its 40c or more.
Title: Re: Quad flight time question Post by: Tanmay.mathur on January 29, 2016, 01:25:38 PM 2500 mah
how much that'll give with a 700gm quad ?? Title: Re: Quad flight time question Post by: ad! on January 29, 2016, 05:32:25 PM first of all u need to know how much current the motor consumes for a given prop set... either do some thrust tests or search online for spec sheet of your motor
Title: Re: Quad flight time question Post by: miginstruments on January 29, 2016, 06:44:35 PM 2500mah with 1045, ll give approx 6mins of flight time. Again actual output depends on what amount of power your motors consumes. But to be safer side 5-6 mins.

It should answer all your questions and even help you decide the upgrade. Happy Flying -Pravin |
