Your arrow should do those maneuvers pretty good for a trainer
type model, My Avistar worked OK.. Once you get the hang of
it.. If your control throws are not maxed out start increasing
them. Then slowly start moving your C.G. towards the back
which will make it do the snaps etc. a lot cleaner.. BUT be
very careful... You know the saying about nose/tail heavy
planes.. And you'll get to re-learn Super light touches on the
sticks for landing... As said above, Snaps etc. are violent
maneuvers and puts alot of stress on your plane, insure your
plane is as ready as it can be on each flight you practice this
and try not to do them too many times with WOT...
