I an considering a TF Contender for my next project. What engine are people using a lot for this plane? I currently have available an OS .46SF ABC, an Enya .50 CX ABC, an OS .61 FX and a Super Tigre S61. Is a .61 too big to fit comfortably in the nose? Is the plane too heavy for a 46? Advise please?

Thanks,
Brian
