RE: Unlimited Verticle???
Mudsurfer,
I concur with MinnFlyer. This is not the plane to hover and torque roll. Put a .46 in it, and fly the heck out of it! If you want to learn to hover/torque roll, buy a Funtana or UCanDo3D etc, etc...
If you put a really oversized engine in the Extra 300s 40 size to hover it, it will be too heavy to enjoy it's great flight characteristics.
