I have spent the 2 years i have been flying, trying to 3D really good. now i have started IMAC and have to say, going to an IMAC event and flying the pattern the whole day is way more fun than just going to the feild for a day and flying 3d the whole time. the people are great and when you have the pressure to fly better than the others, it makes you Concentrate on getting every little tiny thing perfect. I LOVE IT
