Last summer I put a Tower Hobbies 40-size trainer on floats. The floats are 36" foam core floats that I got from Seaplanessupply.com

When I am taking off after it gets into the air it will drop a wing and make for a very hairy experience. But once I get it up in the air it flys perfect.

Could this be caused by the engine (which is an Evolution .46NX) not having enough right thrust or down thrust?

The CG is where it should be, the step is just behind the CG, the floats are perpidicular, the float tips are about 3 inches forward of the prop, and everything looks correct.

Thanks for any input, Josh
