The 370a is a great gyro on the ailerons of a Sabre. The gyro will do exactly what you want, dampen the roll axis. This gyro will not "level" the wing. This gyro will resist uncommanded change. Notice I said resist, since it does not have hold, it will not return to the angle it was blown off by a gust or thermal. The result is you look very locked in on approach.

I have several setup tutorial video on RCJetAddiction.com, just do a search for 370a
