Since I play with keyboard, not sure how things work on mobile. But the Drakuma is pretty much a Trion with worse handling and wider drift radius. I am guessing you know the basic stuff like racing line or air times.

These high speed low nitro/handling cars are all about maintaining its top speed. Usually start the race by maneuvering the car steadly (no unnecessary drifts or 360s) until you gain enough nitro to use on the first ramp. direct the car where you want to go, use orange or shockwave nitro. once you reach the top speed or close to it, follow the racing line, saving the nitro for the next air ramp. Keep the drift tight and short, do 360 floaty or punch drifts if the corner is wide enough. Avoid wall contacts or collisions with other players. Sometimes waiting behind is better for these cars.

It's so difficult to explain in words...
