I have been looking for a SU-27 Flanker myself and have seen the one by Hobby Lobby. It looks nice, but it's a standard Artech SU-27, which means that it is underpowered.

But, don't worry, if you want to have an upgraded Artech SU-27, you'd better buy this from these guys:

Their SU-27 flies fantastic.

If you would like to have a jet with retracts, check the SU-37 by X-flight:

I would like to order both, but I'm a sucker for retracts and the SU-37's canards are not bad either
