Well for me this works pretty well and have even had it work in local tourneys, I usually sj, lay down hopscotch and peakaboo then fly and from there you can do alot of things you can do 2 H low voltages, 1 H low voltage the dive kick, or move around in fly mode to try and confuse your opponent since dive kick crosses up. I have a vid showing this strategy a bit so check it out if you want to see what I am talking about.
Trish is by far my favorite character and the most underrated imo.
I decided to stop fighting it and stuck Chun as the anchor (with Trish and Storm) and whoa BABY is this team fun! Now I just have to learn how to use Chun when it comes down to just her, but damn Trish with Chun legs assist is just too great. Crazy compensation for the scaling!
I think I recall being able to air dash up to 4 times during flight. (No flight time available for more.) It can be difficult to time right since if you try another air dash before fully completing the last one, you’ll just end up attacking.
I believe that you can do up to 3 more specials during flight as well. (Might be during OR after, but I realized I haven’t tested that yet.)
I find it easier to do the multiple airdashes if I a different direction every you air dash.
So for a runaway during flight I do something like: back, up-back, back, down-back
During flight you are allotted 3 more actions however voltages have more startup and recovery than laying traps so usually you only manage to get 2 voltages out before flight ends.
