I flew mine on an evolution 1.00 w/bisson pitts and a xoar 15x6 prop and had zero problems with power. For control I was using JR DS821's all the way around and a regulated 2cell lipo to power em with. Came out around 9lbs dry. It flew fine, tracked straight, tumbled, and would do awesome spins. A 1.20 should make it a rocket in vertical.
