IMHO the Saito 80 is a little low on power for either plane if you wish to fly 3d. Many people are using Saito 100's and 125's on the UCD60 (Including me).

As ram3500-RCU stated, the planes are apples and oranges.

For Learning 3d, I would recommend a plane that is equipped with a power plant at the powerful end of the range for the model. That power will pull you out of trouble at some point. Maybe the U-can-do 46 would be a better option for you. Or if you really want to learn 3d - go for a good quality profile, such as the MoJo or OMP Katana
