RE: Calypso Build
That's a nice looking Calypso. Too bad about the engine troubles. I've had good luck anchoring nyrod guides at each end and once in the middle. Carefully cutting the bottom sheeting on ARCs with an Exacto or single edge razor blade along the glue joint, sanding, then making a new piece has worked fine several times.
Tell me about that rudder. It looks about twice the area of the one on my MT Calypso.

edit: Oh yeah. I love working with Monokote. The iron has to be pretty hot though.
