3D Printed Hovercraft build


Greetings Pilots,
I am working on a hovercraft build and am having issue with one of the ESCs that powers my thrust motor.
The ESC (DYS ESC XSD 30A V2 3-5S BLHeli_S) has a blue LED lit and the motor (a Racerstar DX2306 2700KV ) is running sporadically, like one of the wires is off, I have checked them all and they appear to be secure, I suppose one of my solders could have gone bad, but I'm looking for some advise.

I cannot find any documentation to tell me what the blue LED indicates, however on the other two (lift motors) the light is off.

Additionally, I am only getting about 90 seconds run time before my 3S 2200mAh 70c lipo is down to 20%, this seems wrong to me given the fact that quads run much longer and I only have three motors running. I have one 5" propeller for thrust and two 2 1/2" impellers for lift.

thanks in advance,
Santa

If you're pulling 1800mah out in 90 seconds, you're drawing just over 70a constant! That seems like really high amperage for the motor sizes you have, how are the temperatures on them, especially the lift motors? What kv are they?

Thanks for the reply, I have three 2700KV 2-4S Brushless Motors, I did not notice that the motors were hot, however the original 2200mAh 35c battery puffed so I purchased a 2200mAh 70c and that's fine for the 90 seconds it runs. I would have expected 4-5 minutes like I was getting with my old Blade 350Qx.

Think I fixed my issues, bad solder. Got 2 mins flight time on a 85% battery with 35% left in the tank and everything was nice and cool.

That sounds more reasonable!
