RE: Can't get off the water with Float Plane
Hello , Flying float planes myself, It looks like your problem may lay in the position of the step on the bottom of your floats, This " Step " MUST be positioned on the aircraft's balance point, That is without the floats being mounted,
In other words, position the step where the plans say to balance your plane as if it had Wheels , then mount your floats, Then reblance plane if necessary,
Try this , It should cure it's not wanting to leave the water,
