I agree Arrow. Mine was a nice flyer until I went to the DD tail. The dual was sufficient knowing that it was not going to be a T-Rex. I just hope I can get it back to that stage and working just as well. I really love the heli when it is working. It is what I learned on and would still like to continue learning. I think I just went to far and it became more of hassle with all the crashes. I did see one other mod - did I say I wasn't going to spend anymore - that really looked like it could work and got great reviews and that is the belt drive conversion for about $100. I am on the fence about doing that or returning to the dual tail setup. It is the perfect size heli for my back yard.
