Andy,

Keep the weight as forward as you can. CG should be right behind sponson transoms. Strut weight is critical in the Bud Two wing Hulls.

Put your lipos as far as you can up front, motor directly behind and esc over the motor if possible. Like Bert said CG and strut weight is the key.

Bert. Can you elaborate on that.

Appreciate the advice, will hull flaps help? Or is fwd CG enough

I've built two of the T4s over the years, you get the CG right and boat will run fine. About 1.5 inches behind sponson heals is where I ran mine.

Sam,

The T-4 design had a design flaw. The rear ( secondary) wing has little to no AOA. At low speed the water will come over the rear wing pulling the hull down. So the less transom weight will keep the rear wing riding high above the water.

With any two wing design there's not a lot of air getting to the rear wing to help carry the rear end of the boat through the corners. The prop has to carry the rear end of the boat through the corners. Hull balance is critical. When set-up right hulls are fast and fun to drive.

David’s T4 is a slug in the turns. We will keep that in mind.

finally got back on this, got motor and esc mounted. Got a rudder bracket to work on short transom and worked out 8 s batteries.
