I am a fan of learning new things step by step. This mostly helped me a lot.
So here is another idea but I haven`t tried it yet on the water: Just mount the mast under your board just without the wings. This way you should be able to train the new and different feeling of leaning, rolling, jibing, yawing etc. without having to deal with pitch at the same time. Just don’t stand too aft but more forward on the board. When you are comfortable riding this way you might have better/safer success with actually flying with the wings mounted…. Maybe this idea doesn`t work at all, but I haven`t read or heard about something like this so far…
Other tipps or "step-trainings"?
Ride safe and have fun
