Is there any reason Y i can easily do a stationary roll/side flips on my Raven 50 and T-Rex (as in cyclic full right or left), but it takes a much bigger area to do a roll (both nose up or down)?

Is there a setup issue or is that just the physics of the machine being longer from nose to tail than across the blades?

Thanks

In most cases, your setup (cyclic) would be similar in both elev and aile and not differ too much to make a difference. However, heli has larger mass moment of inertial(resistance to rotation) which is a close cousin to mass(resistance to motion) along the elev axis when compared to aile axis.

This is identical to figure skater holding arms out to slow the piro rate and increase when arms are tucked in.
