Very nice.

This has all of my Aeronautical Engineering feels right now...

However, I am curious as to the practicality of the twin props on the float plane up top. xD

Well the Italians did use contra-rotating propellers on the Macchi M.C.72 which set the world speed in 1934 record for a piston engine seaplane. Record that still stands to this day for seaplanes. Of course I imagined this aircraft being a modern version running turboprop motors instead.

Okay. Just wondering since I haven't seen counter rotating props in a long time. ^^

I'd love to design RCs of these planes though.

Of course, the contraprops on the M.C.72 were like those of the Double-Mamba in the Fairey Gannet, each engine driving one prop without a combining gearbox. That's were the trouble generally comes in as those tend to be quite challenging and difficult (the Allison XT40 and the combining gearbox on the Learfan being two notable examples).

DOn't forget the P-51 racers that use Rolls-Royce Griffons instead of Merlins and have the contra-rotating props. Precious Metal and Miss Ashley II immediately come to mind.

Yes, or late Red Baron which saw run out at Mojave in the 1970's.

Just wait. the Ekranoplans of Equestria are coming!

I love ekranoplans.

The retracting main float on that contra-prop bird reminds me of some British design studies from the Forties while the retracting wing-tip floats resemble the Catalina's. The one that looks like a re-engined Goose has quite attarctive lines and the twin-boomer looks like a Bronco derivative, but much changed.

Some attractive aircraft there.

Those are some nice sketched... you may be a plane nut like myself.

Maybe I should talk with you and give you the three view drawings of a home built aircraft that's on my drawing board to see what you can do with it... I never could do a decent perspective drawing to save my tail.

Once again really nice designs

Top one is a lovely seaplane-racer. Reminds me of the I'd love to have that, but that shallow a canopy, it must be hard to see out of. The cockpit position reminds me of the Mig 1 and 3,

Sorta an updated Sea Duck with the second, pretty nice.

Pushprop version of an OV-10A Bronco? What's the advantage? Allows for more wing loading?

Heli is beefy and Russian-looking, like an updated MI-8

Well I envisioned it as one of those unlimited class air racers where streamlining takes precedence over things like visibility.

Just playing around with different ideas for a forward observer/COIN style aircraft. Like I said, when I start drawing these things I have no idea what I am drawing. It just sort of comes together on the paper.

For a forward observer/COIN aircraft, how about combining elements of the OV-10 and the Edgely Optica. A more powerful, tandem-seat Optica with a stores capable wing could be an interesting bird. I do like the approach you're using here, replacing the OV-10's twin T76 engines with one larger engine driving a pusher propeller.

the big benefit for a COIN bird would be greater protection for the engine from ground fire, possible even some benefit against all-aspect SAMs as the booms would provide some measure of masking for the engine.

Very plausible designs! The twin-engine seaplane reminds me of one of my concepts:

Cool drawings!

I love that sleek seaplane on the top, it looks like a more advanced version of the Boeing Monomail, another beautifully sporty aircraft.

The middle right aircraft looks like the Mohawk, one of the few fixed-wing aircraft in the US Army inventory and one that caused the Air Force to get in a bit of a tizzy because fixed-wing aircraft was their domain, thank you very much, and that was supposed to be the division of labor when they split with the Army back in 1947, so why the heck are ground-pounders crowding the sky like that?

Top looks like a streched out p-51a mid looks like a North American Rockwell OV-10 Bronco and the botome looks like one of Mikhail Leont'yevich Mil family of helicopter gunship good job on the rendering love you,re work.

Sketches he says... I think a lot of people would be happy if their finished pictures looked this good.

Have you ever thought of doing livestreams? I think I'd like to see you how create pictures like this.

I'd be happy if my finished pieces looked half this good.

love the race hidro!!! is like a macchi-castoldi MC72 but even more advanced XD

this is nice.

That sea plane reminds me of just how much I would love to own a PBY Catalina converted into a small RV.

You need to add a 'step' to the floats on your seaplanes, otherwise they won't be able to leave the surface. The step should be directly below or just behind the center of gravity.

Also, on your racer, the main float should extend past the disc of the propeller when lowered so the thrust of the engine and surface tension drag doesn't cause the plane to tip forward and the float to 'submarine'.

I love the racer's lines. I'm sure it could be do-able in an electric model. Can you show me a top view?

There was a day when I used to do similar doodles. Now I feel I have to "finishI" everything, so actively avoid starting something I know I won't ink.

I have a question. if you set up a jet like the German Volksfighter. ( http://en.wikipedia.org/wiki/Heinkel_He_162 ) and put a pontoon under it like the Kingfisher, ( http://en.wikipedia.org/wiki/OS2U_Kingfisher ) could you have an effective Seafighter?

Wow... Wish my pencils were as clean as yours. And you say those are mere doodles? Sir, you are selling yourself far too short.

I love that pusher-Bronco.

These were just doodles???

It is what I call them when I just putting lines of the paper with no clear idea in my head what I am drawing. I throw down a line then stare it, as put more lines downs an object forms on the page and develop it from there.

Modesty AND Talent...
