Hi Marc I originally was going to go ducted fan, to keep the props well protected, but like I said, the inherent limitations and difficulty to design a ducted fan lead me to more traditional routes. I rendered a quick fix using the Be-103's (thanks for the link) engine mount as the inspiration, and added a water line to the rendering, see if you think that would work better. Thanks again! Brent

Hi Len, thanks for the advice, and I completely agree with the main wing pontoons for stability. I was thinking about stealing a page from the Nazi's seaplane design book for the main wing pontoons. Remember the Do. 26? it had retractable main wing pontoons... I figure if they could do it in 1937, I could do it now. I do have good reasons to believe that the canard at water level will actually help the plane to NOT be a submarine, as opposed to making it into one... the taxi rules will be simple: always pull up. plus in flight it will be more efficient since lift vortexes will drift down and out, causing the rear wing to more efficient. I'm still designing before I commit to making a working model, which I know won't prove if the real thing will work, it's just supporting evidence. Thanks Len! Brent

Thanks for that advice! I too was concerned about the engine height. my design until 2 revisions ago had this being a ducted fan, but the increased drag, and complexity and weight of the duct caused me to fall towards a more conventional propeller. The front wings are intentionally low, they will be at the water line until the plane gets up on step. The design process on this I think will take no less than 2 years with the amount of time I have currently to dedicate to it. so this forum will be great for all the suggestions, and hopefully I'll have a workable design pretty soon! Thanks for your comments and links! -Brent

Hello everyone, I've been lurking for a bit now, and thought I'd finally register and say hi! My name's Brent, I've been interested in flying since I was very young. The plane of my dreams does not exsist, so I was going to attempt to scratch build it, and would love to hear your comments or suggestions along the way. I've always wanted a 6 place amphibious twin. Below you'll find my preliminary 3D rendering. I'm using my skills as an accomplished R/C model airplane builder, but I know those don't all carry over to real aircraft design. I am beginning the process of making a working model for this plane. So far I've proposed to use 2x230HP Mistral engines. If anyone knows anything that could help me reach the goal of designing and building this dream, please let me know! Thank you, Brent
