Well Jeff it might be trapped air in the bow I'm not that sure. We were on a schedule yesterday and I only had an hour there to play.
She dives stern first. Once under she's fine but it was quite shallow at this end of the lake. Until I have tested her more it's the safest place to be.
Here's some video which will show you what I mean. She need bigger rudders for sure and I plan to make slip on so they can be removed for display. She had plenty of head speed bu needs to sit lower in the water to keep the prop from cavitation.
That just requires a bit more water in the tank to lower the free board for runs and back up full at the dock.
