The Tiger II uses a .40 -.46. The Tiger 60 uses a .6o. The Venture 60 uses a .60. If you have a .40 -46 you'll need to get a new engine for the Venture.

In either case, especially since it is only your second kit, I would strongly recommend that you go with the Tiger. It is a MUCH easier build, and an airplane that is an excellent second plane that is also capable of almost anything.
