From the description of the a/c oscillating, I'd guess you're using auto-pilot 
heading hold/wing-leveller.  Try it without and you shouldn't get any 
oscillation.  You can also get pitch oscillation or porpoising in some a/c at 
low speeds with AP alt hold too - that can be tamed by increasing the 
elev-adj-factor.
