The wings are pretty decent, although not strong enough to let the wearer fly as well as pegasi in extreme conditions. Only who knows its inside mechanical parts through and through can control it well, which means me. This thing is still pretty much a prototype, and I don't want to be the root cause for a large number of accidents." Tinker sighed and finished his second muffin, drinking down the rest of his milkshake. "It'll take a few years to prefect the design and materials." When folding his wings back, only his horn glowed and not any part of his wings nor theirs casing on Tinker's back.
