Currently building a -7A and soon to be starting on the wings. I will be wanting to do an occasional roll (although I have never tried it before & hope I don't toss it) SOoooo....I was wondering?

Should I put flop tubes in Tanks ? (I'm not even sure what those are yet)

What about inverted oil system?

Or with just an occasional whoop-ti-do, am I OK ?

Flop tubes and inverted oil are for inverted flight or negative "G" manuvers. You have to decide if you want to fly inverted. These are not needed for standard aileron rolls or loops as (hopefully) they are positive "G" manuvers.

I would opt for a smoke system before I added flop tubes and inverted oil, JMHO.

A search for inverted fuel or inverted oil will get your everything you ever wanted to know bout the hows, wheres and whys of the uses of these systems. You will find much discussion and learning opportunities from others who have asked the question as you have.
