RE: setting up Lanier RC Mariner 40
I have the big 120 sized Mariner. It's a great flyer with no bad habits. I didn't like the way it turns so I coupled a little rudder with the ailerons. Watch the step area for leaks. I glassed the belly on mine with a very light glass cloth to make it tougher. Make sure the front hatch is very secure because, if it comes off, it's in the prop. Screws, not magnets. Compared to a foamy, it's going to land much faster and require more space. It's a fun flyer. Good luck.
