Title: Hi, can you help me improving my build. (250 drone) Post by: Doodeep on August 13, 2018, 10:01:06 PM My build configuration -
2300kv cobra motors 20a BeLhi opto esc Cc3d flight controller. Cheap 250 carbon fiber Chinese frame Zippy 2200mah 45c lipo battery The only problem I m facing is that sometimes after a good 3 min flight time the quad just falls off from the sky. I don't know if the ESC don't match with the cobra motors or the flight controller is not able to handle the motors. Other than that it just flies great!

Your esc should be having higher amp rating. And does the esc or motor get hot?
Title: Re: Hi, can you help me improving my build. (250 drone) Post by: Doodeep on August 14, 2018, 06:59:44 PM No it doesn't get that hot. Not the ESC nor the motor. But it does get a little heated up. The maximum continuous current for my motors are 17 amps.
Are my esc's too low on the quality? Or do I need to upgrade my FCB? Title: Re: Hi, can you help me improving my build. (250 drone) Post by: AL HAM SHARI on August 14, 2018, 07:18:40 PM Your escs are fine, try testing your quads without props on and tell me whether it happens when not flying.
Title: Re: Hi, can you help me improving my build. (250 drone) Post by: sim_tcr on August 15, 2018, 07:21:52 AM I also run a similar configuration but with 30a blheli_s ESC and 210 frame, never faced such issues.
From my testing continuous 10 mins of run, the temperature of any component never raised above 100~F. 2300KV motors i use, maximum load current is 19.2A. As per experts here, in realty this can be little higher. That’s the reason I went for 30A ESC to get some breathing space. Title: Re: Hi, can you help me improving my build.

N I guess my flight control board is faulty going to change the FCB let's see if I face the problem again. Title: Re: Hi, can you help me improving my build. (250 drone) Post by: AL HAM SHARI on August 19, 2018, 07:55:40 PM It maybe due to your fc or your firmware.
