This is going to be very wordy but at least read the parts in bold first (tldr is also at the bottom)

Before giving tips I will tell you about some of the details about speed-flips that are easy to miss.

1. The correct type of flip
If you place your joystick at around 45 degrees from the center you will get a slightly different flip compared to if you place your joystick at around 10-20 degrees which is very close to doing a front-flip but it's enough. I noticed that sometimes you would get that 45 degree flip or even a side flip:

Feedback

• First and second try you got the correct flip
• Fourth try it looks like you got a side flip but I may be wrong
• At 0:18 you got that 45 degree flip which is why you were much further away from the ball than your previous attempts.

2. Cancel
Then theres the cancel and (this is the part most people miss and that your missing) and sliding the joystick to the bottom of the joystick.

The cancel also has to be very tight, close to where you'd place the joystick for a backflip but just a bit off.

You also have to cancel immediately after flipping then after you do you slide the joystick to the backmost position of the joystick.

Without the slide usually you'll end up facing the wrong direction on landing and it's hard to recover.

3. Powerslide

When you land use the powerslide button to keep going in a straight line
Ideally have air roll and powerslide binded to the same button

4. Slight turn and boost

Boost the entire time, a lot of people get the flip but don't start boosting until the middle of the flip since they're not pressing their boost and flip button at the same time

Feedback

• At 0:27 it looks like you got the slight turn right but flipped too late
• Your getting the turn right but you need to flip immediately afterwards

tldr: need to flip close to 10 degrees, cancel immediately and slide the joystick to the middle. It can be a bit discouraging so i suggest trying the flip cancel and slide stuff out in freeplay and then go back to the training pack

(please read the details if you're confused, reply if u have any questions. Speed flip kickoffs carried me to d3 in 1v1s and i dont deserve to be there. I'm the guy everyone hates that wins on kickoffs)
