Recently completing these, you can do it! Do not be afraid to bounce from any surface when turning in tight places. Also, there is a really good build you should use for aforementioned trials. I believe it is: S One Adamant Modded Thunder God Motor S One: S3 Propeller Low Cost Turbo Lightspeed ESC It will make S Speed and A (?) Durability, which is the best combo you need for these. And do not forgot there are shortcuts in some races which, if pulled right, can save you 3 seconds without an issue.
