the mono (wing) is much better than the bipe, it is faster, more agile, but takes some fine tuning to get the best flight (trimming elevator shafts etc.) but overall once you think you can handle it you should try it. Also, yo can always put the wings back on if you dont like it (just take them off carefully). I personally love the mono because with the elevators down it does cool swooping turns. If you remove the bottom wings try experiments with adding extensions to the top ones. By adding the bottom to the top i was able to increase the climb and gliding capabilities and do a backflip! the extensions are much harder to control and to turn them efficiently the motors should be moved out. As for the jet i have yet to find one but from reviews the design of them helps them glide a lot better and handle wind but they are no longer indoor flyers.
A question from myself: DOes anyone out there have the airhogs titan? its a plane with a 3ft wingspan and 4 ducted fan engines. If so is it good? and how much is an average price?
