I guess I used term snap rolls incorrectly ,,, sorry about that ...

I'd like to perform multiple rolls while flying horizontally with ~45 degree nose up.

What this figure name is? Barrel rolls????

I think ruder and elevator gyros may assist pilot if pilot will start this figure with 45 degree bnose up and full aelerons one or another direction

Could you comment on that, please?
