Wish I had a simulator,I can see where it has speeded up the learning curve with others,after 3 years of trying,finally I can do a decent torque roll. Its funny,while the few of us "hard core" flyers trying like maniacs to perfect our 3-D, the others flying hardly even pay attention to us anymore. I did a harrier landing and none of them were even watching or seemed to care. To me, it was a mile-stone in a long and difficult endeavor. At least one other 3-D'er saw it and had some praise for me. I think I'm only the second guy in a club of 100 members to do this. It does seem like a "fad" to the majority of my club but I think its here to stay,hell, I've heard some full scale aerobatic pilots have taken up flying RC 40%'ers to see if they can do it with a full scale. Imagine, a full scale doing a torque roll on the deck! I think they might have to wrestle with the thrust/weight issue a little bit.
