The Aztec is docile - it has the same wing section as the Cub - however at max. weight it will bite you on one engine just as easily as a Seneca. Performance loss is still on the order of 80% so don't expect anything flash and *all* except in-line thrust types will turn turtle and spear in if you mishandle them asymmetrically.
Flight test/checkride conditions are usually misleading. They're almost never at max weight with only two up + fuel, and sometimes zero thrust isn't as close to slightly-less-than-zero as it should be. The more load capacity of the aircraft the greater the differential of training weight vs full.
