I flew my EF Extra 78" at my first IMAC contest this weekend and took a second place. Real happy about that. The Syssa ran great all day. Started with one or two flips on each of the 6 rounds. I ran a 18x6 Xoar prop and had to run it hard to get over the top into the wind. At the end of the day on Saturday I noticed that their was oil or grease on the hub and between the hub and crank case. Did I blow the front bearing? That might explain why it was struggling on up lines if it is responsible for holding the crank case pressure. I haven't checked the rpm's, I haven't even unpacked yet.
