Dan Matuschek is a man with a wealth of experience in the custom car fabrication industry.
He was introduced to the Mud Duck designs only recently but was interested in experimenting
with FFF (fan fold foam) for the larger versions.
My initial suggestions to Dan were that FF was a good alternative for the "Sport" versions
but I was not recommending it for the larger versions without adequate reinforcement and
structure enhancements, which would likely offset the weight savings over foamboard and
also eliminate the "simplicity" and "ease" associated with building it from foamboard right
from the get-go.
Well, little did I know of the knowledge and ingenuity of Dan at that time. Dan ventured
forth with a few versions of the Mud Duck and Agri-Duck, in large scale, using solely FFF
and other "blue" foam material and employing a laminating method that added only marginal
weight to the overall structure when done properly.
Dan makes this look very easy and may have opened up a lot of possibilities for many
builders. As for its use in Duck construction: It all depends on your goal, do you want to
get in the air as fast as possible, or would you like to build the lightest and strongest
(and possibly cheapest)structure you can but adding time to your constructuion? The choice
is yours and Dan's methods gives you the option.
One last thing. These videos are of a version that Dan modified from the plans that
employs a one-piece 8 1/2' flat bottom wing. This is not to be used as a reference for
building the Mud Duck in its conventional format.
