Hi Paul
Here are the cooling system photos you requested. The first photo shows the water radiator below the engine. The next shows the oil cooler ,there is an identical one stacked below it.
  Thank you so much for this website to for all of the same interest to get in touch. There were a
Few others on this web site that had questions & comments but I don’t  have there E mails,
so below The pics. And a few responses .

Mark Wiese  I built the hull in about 1984 so I used Kevlar on the bottom. And yes I saw & studied the B 103 very interesting.

Kelly Troyer  I do have the EC 3 manual just working through it is my own stupid challenge.
And Yes I spent some time circling the Sea Dart at Oshkosh. Our plane is a bit larger than the Dyke Delta which I admire,but attempting the amphibious version I had to keep the prop out of the water and also about eliminate the spray factor. The control surfaces are piano hinged on the bottom to keep from scooping water and ripping them off. They are balanced internally.

The empty wt 2200#. ( got a little heavy) but with a + or - 6G wing loading capability . I had to extend the nose wheel to increase the angle of attack which caused a little more engineering to cycle it back to its original length so as to fit back in the wheel well. I designed the plane in 1981 then built a 1in-to the ft. scale model then a 1/4 scale radio control model which flew beautiful then started the full scale in 1983. I’m 75 yrs old and pretty much have tunnel vision on getting her in the air & enjoying it while my health is good.

Thank You All for your insights.
