First questions : how are you doing it right now ? From what turtle do you start flybash and what are doing during your flybash ?
Here's the answer, there aren't really any ways to make it easier but there are a few thing to keep in mind.
No1: make sure that you are as high as possible after the bounce before you start to mash. Practice this simply by grinding and getting a feel for it.
No2: if you go for the version I use where you jump up to the platform then you need to know when to jump. There are 3 hits in the attack cycle, the 3rd of these forces you to drop a little bit before you can jump making it even tighter. Make sure that you jump out of the 1st or 2nd hit for biggest window of success.
Beyond that there's no real trick outside of grinding it out.
I could also recommend learning a 1 handed mashing technique where you vibrate your arm to lower the chance of miss timing a hit or jump.
But... How are you supposed to know which hit you are on? The punching is way too fast to be able to count along.
They have different sounds.
Not saying it's easy. That's what the grinding is for :)
And I want to ask how to do dashbash?
Alternatingly mash dash and attack as fast as you can against an enemy or similar.
The really most important part of that flybash is to mash jump after stopping hitting fast enough to hit that frame that makes you jump without losing height first. That's about it
you either get that and get the trick, or you don't and you fall
Jupp, that's why one handed mashing with vibrating arm is so strong. You can easily move from button to button :) though in no way required.
It's kinda like forcing in a puzzle piece instead of figuring it out xD
I'm just too stupid to press the left stick forward AND spam jump fast enough at the same time...
I just break my fingers and fall
