RE: Seagull Yak?
The 1/4 scales hinges like I used are just slightly thicker, but a lot stronger. The stock ones would probably be fine, but I just prefer to use what I know holds up well.
Runner, just fly that engine. Set it just a tad rich, and fly it. I might run two tanks on the ground before I fly a Saito. They really aren't what i would consider truly broken in until you run about a gallon through them, but are fine to fly as long as you leave them a little rich.
