A simple design and my first stab at a large plane. Take off at around 160-170mph. Has landing gear as well for ground take-offs. Make sure to retract landing gear before hand if attempting a water take-off/ landing. I'm quite new at this so any criticism is appreciated. Thanks!

    @LatteFun The majority of pitch issues can be fixed using pitch trim. Sometimes it's also a good idea to change the airfoil shape of each wing. Flat Bottom gives maximum lift, Symmetrical gives it neutral lift, and Semi Symmetrical is in between. If your aircraft tends to dive, your main wing needs to create more lift, or your horizontal stab. is making too much lift and needs less. It's the opposite if it tends to climb. I generally start with the wings at flat bottom or semi-symmetrical and the stabs at symmetrical and adjust from there. The last thing is, if you have a high speed aircraft, it many times will fly level at lower speeds but climb or descend at high speeds. The best way to fix this is setting all wings and stabs to symmetrical. I hope that answers your question!

    @StudentAV8R Thanks so much! Would you have any advice on what I could change? I need to know how to get my planes to level out when flying instead of slowly climbing or diving.
