My son and I are looking for a .40 sized nitro powered 3D
plane. We like the Sig Somethin Extra for many reasons.
Can anyone tell me if it will torque roll? What size engine?

I know it needs more rudder surface for KE, but other than that how
does it stack up as a 3D fun flying plane?

Currently we both have 3DX'x that we love and are looking for something similar
in a nitro plane.

We like the flying characteristics of a UCD .40 but they are fragile.

Considering the Model Tech Magic Extra 300L too ... not sure of the durablity.

Thats one reason we like the Sig SE. It is very durable for not so perfect landings.
