Paul,

Sorry to hear your kit only has three sheets of drawings. My kit came with one page of pictures and some typed directions... very vague directions at that. With prior model building experience this kit should go together with only a few problems. Dumas needs to redue these. I have had many questions asked of me and what I am doing on my Darby sent to me on my website. I will have a large area with lots of information to help. As for the motors... you would rather have too much than not enough. The motors I got from Harbor Models (Pittman 3700) have lots of torque and will handle what ever you toss at them. I have tested my Darby in the tub and found that the props cavitate at halh throttle. Remeber that in this situation the tug has held stationary and is not moving through the water. But the one important point is that running the motors directly I still have enough power/torque to turn the props without overloading or over heating the motors. Plus I don’t have any noise from gears!!! Although I don't have the noise I do have higher RPM's at the prop.
