I have finally found a way to do 3d aerobatics on fms! First donload the simulator from the fms website, then, choose your planes from: http://kimagure-hikoki.hp.infoseek.co.jp/Hanger4/

I have found the planes from the above site capable of most 3d, you can even hover them eith practice. Plenty of control throw on the models. Most of the avaliable aircraft are profile with some giant scale models thrown in.

Happy flying!!
