I don't fly enough (used to fly at least once a week and don't even do that now) and have a simulator that gets little use so these are areas to work on -

Some of the most impressive flying skills I've seen were in videos of competitions taking place indoors where pilots appear to be flying exacting routines following a set schedule; Having seen these demonstrations gave me the idea to ask here:

Are any of the foam electrics with the cruciform fuselages and flat wings like those from Twisted Hobbies or any other source worthwhile having around for 3-D training?
