No. The 52" is specifically built for vibration-free electric power. An IC engine would destroy the airframe in short order.
I have the 52" e-version. I get 7 minutes of good flying out of ThunderPower 3900mAh 4S batteries. I could stretch that even more if I wanted to pay the weight penalty… and this airplane will handle it. Lots of wing area.

Tower Hobbies/Great Planes has a fifty-something inch Extra that is perfect for your OS .55. And I suspect it will fly better than the the AeroWorks example in that size; I've seen three of them, flown two, and all were heavy pigs. They flew okay, but needed LOTS of power.
