an 82 will work great without flooding stock mounted, just use a easy fueler valve mounted higher than the carb.
i used standard servos on mine and had no bad happenings with them.
firewall is good to go, the tail needs to be done with lots of epoxy and i used sullivan tail wires.
the main gear will break off clean with the first hard landing, just dont install the wheel pants untill after this happens or they will go right through the wing bottom, and when it does happen you will see how to reincorce because it will all be opened up.
this is the reverser i have used for over 2 years, good one and adjustable

i used dubro pinned hinges.
use a14x4w apc on the 82, i also used a sulivan tailwheel, but the stock will do ok!
good luck agexpert
