Title: Re: Quadcopter unable to fly Post by: Balakrishna Reddy on June 11, 2017, 05:52:33 PM Looks like the motor kv is very high however that's not the problem but a 450 quadcopter should not have a 1800kv motor.
What is the propeller size? What is All Up Weight(AUW)? It would be very helpful if you can post a video or link to video. Title: Re: Quadcopter unable to fly Post by: Deeshank on June 12, 2017, 11:01:51 AM props are in correct in orientation ? that was the mistake i made on my first quad :D :D

Title: Re: Quadcopter unable to fly Post by: Rcjabalpur on June 14, 2017, 01:47:01 AM I think so he has messed up with the motors , probably went with 18 size motors . The second possibility is the props , what size are you using ?
Title: Re: Quadcopter unable to fly Post by: Param grewal on June 14, 2017, 02:50:21 PM 3500 mah
And the props are 10x4.5 Title: Re: Quadcopter unable to fly Post by: Param grewal on June 14, 2017, 02:52:22 PM Also , yesterday i burnt an esc so ordered new ones
Title: Re: Quadcopter unable to fly Post by: rajjames on June 14, 2017, 05:20:53 PM Hello Param grewal sir,
Sorry that your ESC is burnt. To try to understand your setup and to try find a solution, can you please fill in the "?" marked specifications from below consolidation: Frame : 450 size Motor KV: 1800 KV Motor size: ? (eg. 2212, 1806, etc) Motor brand: ? Propeller size: 10x4.5 Propeller brand: ? Battery capacity: 3S 3500mAh 30C Battery brand: ? Is the battery new: ? ESC Current rating : 30A ESC Voltage rating : ? (is it 3S rated? probably yes, I think) ESC brand : ? ESC firmware : ? (SimonK, BL_Heli, etc) ESC Calibrated : ? Is the newly ordered ESCs exactly the same as above : ? Flight controller : kk 2.1.5 [Is there any verification required from software configuration point of view] All up weight : ? (including battery, antenna, etc) Are all the components(especially battery and motors) new? or are they used? Are you comfortable and sure about the direction the motors rotate and which propeller goto which motor? Sorry for bombarding with a lot of questions, but I hope you can understand that a clear picture always helps:) [I am asking for components' brands because it will be easy for us to google for data like rated max current, thrust, etc. for that particular component.] Let us know if you have any other observation as well. Title: Re: Quadcopter unable to fly Post by: A_Qaiser on June 14, 2017, 06:47:49 PM Using an 1800kv on a 1045 props is overloading them,and that might have killed your ESCs. Try some smaller props ,maybe 8045 or lower I guess.
Title: Re: Quadcopter unable to fly Post by: Rcjabalpur on June 14, 2017, 09:53:47 PM What size motor are you using ? 1800kv is a fast motor wont take those props very well ! Please please let us know about the motor .
