THanks for all the replies guys
Good to know that the motor choice isnt all that critical as long as its set up right.
I ended up picking up the HobbyWing 21.5 with the extreme esc as a combo for very good price.
In the end the fixed timing makes it one less thing i need to mess with
Was also suggested to go with around a mid 60s mm roll out which should work well with this motor combo.
As long as it is competitive and doesnt blow up on me i'll be happy
If i have issues i can always try another motor and see how it goes from there
