I still build 1/10 TFH and Runner bottoms for real drag racers to run when they are relaxing. There has been a loss of the Parma 1/10 motors and I have been wanting to build a bigger boats but did not want to go to 1/5 or 1/8 scale too expensive for the electrics. So I found a dummy motor in 1/6 scale that there is a good supply http://www.google.com/products/catal...ed=0CGIQ8wIwAw
I am starting to build a plug for the FTH and Runner bottoms in 1/6 scale. The TFH boat will be 38 inches long and 14 inche wide. The Runner Bottom will be 35.8 inches long 10.83 wide at the transom.
This is my start.
