Well look at that.
Revision # oh I've lost count.
It was suggested the small rudder could be adding to the issue.
So I removed it and installed something about twice the size.
It is static. I'm now using differential trust to steer.
I then made a haul that is 2" tall at the front, 2.75" wide and 12" long.
Just enough to get the props off the ground.
I was even able to recycle the pontoons! Still need to work in securing them in nicely.
One loosened up during the first test.
New nose and lower haul section.
The 10x7's scrubbed the snow/road too much so I put on the 9x5's. I have some 8x4's coming in as well.
The 9x5's worked but I will still raise the motors to the top of the wing like the CL-415 just to make sure I can clear the snow if its deep.
BTW differential thrust steering is a hoot.
