RE: Ziroli - Tubinator E
Mark, you will find it to be a very stable , preditable flier. Keep in mind it is not a 3D plane. If you do build it with retracts the weight is going to be a bit high. The other thing that will help this plane out is to keep it as light as possible. It is going to take a fan unit with at least 2 and a half pounds of thrust.
