Hi I have one of these P O S. It took three tries to get it in the air,it wouldn't come off the water. Went to a larger float and took the2 1/2 degrees of down thrust out. It took off and rolled to the LEFT and crashed. I called the the v mar people and to no satisfaction,I have a new wing for it ($85.00) we'll see what happens. I wouldn't buy there products. Thank you Don.
