You might be right, bigger = stronger, and its less vulnerable to ripples in the water.

So wich size would you reccomend, and can you put down the full names of the equipment I should use? Like wich type of motor, wich screw (Octavus, right?), wich rudder, all that stuff.

Im gonna make a nice page about it with step by step build logs, so other people can step in more easily. So its kinda like reading instructions from a lego booklet, but then a little more advanced. Just an idea.

Thanks for helping me out, I cant wait to start on it.
