Well do you want modelling suggestions or do you want suggestions on the craft? Modelling suggestions I might not be any good with - because I'm really new to modelling well... but suggestions on what I would add to the model - i can think of some... only just how "realistic" do you want it - If you are looking to fantasy airship type thing - you can pretty much add whatever the hell you like. After all - Fantasy means you can pretty much do anything you want. However, if you are looking at something a little more realistic - ie... grounded in Physic's - I would suggest looking at normal airplanes, and especially experimental planes, and seeing which characteristics are always there, and which are important. You don't have to learn much about physic's to know that a helicopter needs a stablising rotor to prevent it from falling out of the sky while going round and round and round. Or that a plan needs some form of tail rudder to help stablise drift, and yawn. WiNC
