RE: Seagull Ultimate biplane 90 size
How are your Ultimates flying with the engines you have chosen for them? I'm thinking about the new Evolution 1.20 for mine. I'm using the Evo 1.00NX on my Skyshark Edge 540 and really like how this engine runs. After it was broken in and tuned properly, it has a really smooth idle and very good transitions from idle to WOT.
