Been playing around with this drone to see if i can get it working properly and was told that it seems to drag on the ground on one corner, so changed the motor that was causing the problem and seems to turn as good as the others now, but below is now the problem i am left with.

Just got one given that has got me stumped. Its a Hubsan 501s x4 and it does not fly. Starts up and i can calibrate the compass ok. all lights seem to work as should, but 2 things are happening.

(1) on the screen advanced controller monitor it has four bars that can be altered by the small buttons on the bottom area on the monitor, one of these the left hand one that is left upwards, is red and the other three are normal green. don't know why it stays red.
(2) Nothing happens when i pull down and right with both sticks to start the motors. I changed one of the motors which was not working properly and i have had all four working well, without lifting off the ground, but now motors not starting. all lights are confirming that all ok apart from that one at the bottom on the screen of the monitor.

Anyone any ideas please.
 
Hi Phil is it the newest one with brushless motors or the old one with coreless motors can you attach a photo if your not sure
If it's brushless check the esc and wire to the motor it will have 3 wires to each motor
If coreless it will not have an esc and will only have 2 wires if it is coreless there is a good chance the motor is damaged
