ic2 electric jetpack help

[thepowdertoy]

Help when I use the industrial craft 2 electric jetpack, I cannot go to hover mode. I already press M key when I push the jump key (space) but there is no writing that shows I entering hover mode.

Did you try to hold down the jump key and then click M?

yes

EDIT: It works! Thank you.
