I used a 4$ hula hoop and 4 crossed dowels, very light, but still gave me gyro feedback. Dumped it too soon. Paid for it several times. I should have just popped for a better gyro with in-flight adjustment. Get some Very light training gear, use it when learning side hover and nose hover, the first few flights of each.
I still dont do good nose in hover, but I'm working on it whenever I feel froggy. I'm loving loops, rolls and holding inverted at the loop tops a bit now.

Heli's are Pure Adrenaline to me. Lets Fly!!!!
