Replying to Problems at jumping on skis

Hello everyone :),

i am trying to learn to jump on skis and to get comfortable in the air and trying to hit rails, but i have one problem.
When i try to jump its like i need to slow down and then to pop a little bit with my skis, after i jumped or when i try to jump a little bit it feels like my feets are loosing control. And thats my fear -.- im thinking every day about it if i shouldnt do another sports :(. Im skiing since im 4 years old now im 23. And since last year i am trying to get into the park because im skating and i like rails and jumps but yeah i got problems that are demotivating me :(.

I got the head framewall skis and i got 0 problems when im skiing.

sorry for my bad english i hope you can give me some tipps.

Thanks

PS: I am from germany if someone wants to go in the park and shred together :)
