I could really use help, i would like my character to walk and fly

Hello all, im nearing my wits end attempting to make this character work

I want to set up a system similar to tribes ascend

You can walk, and you can jet around with physics and boost and all that good stuff

What is the best way to go about doing this?

I have the problem right now where if i use physics, my components flail around like that garry’s mod mod called prop hunt

However, if i use set actor location, i cannot maintain any speed or velocity at all

Please help
