Don't have that plane but I have considered it in the past and have read many posts about it, Go with the Mag 53, It will have the power to make it fun and help with the balance. The 40 will probally only pull it around underpowered for real Fun flying, most say the Pizzazz is not a true 3'd plane but a Fun Flying type.

Lurk in this forum and you will learn the best planes to get for 3D flight, Keep an eye on OMP's Profiles, Accell hobby, Extreme Flight, Morris Hobbies, Swany's House Profiles, Are the current favorites.

Have fun and let us know how the Magnum 53 holds up, I'm starting to hear some positive info. on that engine.

Also search the pizazz name for other threads/info in ARF forum and Profile and Fun flying plane forum and this forum, should be many build threads.
