Killing King Dodongo with Bombchus

Hello,

My name is DarkslayerTV and I'm having a lot of trouble taking down King Dodongo with my bombchus! I've tried a couple of different positions and do my best to get my angle but no success! Was curious if you guys had any tips or could deduce my problem with the video below!

Thanks! :D

You were too close to Dodongo when you started the hover, the spacing is very important.
