I'm getting ready to start on a Typhoon 2000 (more than likely all wood) and have a YS FZ120 on the shelf. Is this enough engine or am I going to need to get a 140?

I'm really just starting out in precision aerobatics and am by no means an expert. I have been practicing/goofing around with a Widebody with a YS FZ91 in it for the past few months. Just thought the Typhoon was a pretty plane and got the itch to build one. I guess I could try the 120 and upgrade it later if I feel the need...

Any input would be most welcome!
