Help whenever I try and ascend using any of the fly equipment e.g. Swift rings, Ring Of Arcana ect.

It goes up in chunks( 3-4 blocks at a time, and stops and I fall back down.

It seems like one of those rare bugs that happen when some file is missing after install. I do not know how to fix this. Try deleting the complete modpacks/tekkitclassic folder and installing latest version of java. I can't think of anything else
