Finally had a real test of how the changers that I made during the off season turned out under racing conditions at Lake Walyungup.
The wider back wheels have given much drive forward.
Moving the mast post back appears to give the yacht a much more balanced feel.
The 50mmx20" front wheel now gives excellent steering through the corners.
The front suspension that I added from a mountain bike from the tip works great(the video shows how well it is working)
Very happy with all the changes.
