The final GB of the season will be the Bad Idea GB and this will be the place for your general chat

Open for discussion gents 

The bad idea concept is a very good idea !! 
I like to join the party 

I'pretty sure the idea behind the Piaggio P.7, also known as the Piaggio-Pegna P.c.7 could be made to work now:
a Schneider Trophy racer that had hydrofoils instead of floats. It needed a water prop to get up from the water AND an air prop to take off and fly. Thing is, the clutch for the water prop needed to be disengaged and the clutch for the air prop engaged, to make it work. Depending on which website you read, there were problems with the clutches, or they couldn't get pilots that had enough hands to operate them

ABSOLUTELY! 

I've always thought the Pc.7 would be the ideal candidate for holing the world water speed, and world air speed record during the same 'flight'! Break the water record during take-off, then climb out and break the airspeed record, simnples. 

But I've done that already here https://www.whatifmodellers.com/index.php?topic=48848.15



[Later[ Somewhat irritatingly I can't for the LIFE of me remember what that bit of Whiffery was that I mention at the end of the build of the Pc.7! Obviously I never did fit it, whatever it was, darn it.   

The Pc7 model really needs the unbearable stench of burning clutch around it to produce the full ethos of the aircraft!

A few other aerial devices you may wish to consider are:-
Caproni Novoplano  Ca60.  Handy if you have several sets of spare biplane wings to use up  in your bits-box..........this is the one Winkle Brown said would not look out of place sailing up the Channel with the Spanish Armada      https://en.wikipedia.org/wiki/Caproni_Ca.60 
Stipa Caproni . The front view looks like a Tiger Moth emerging from its chrysalis   https://en.wikipedia.org/wiki/Stipa-Caproni
Christmas Bullet.  Wings  fell apart in flight   https://en.wikipedia.org/wiki/Christmas_Bullet
Rockwell XFV-12.  A VTOL aircraft that couldn't!    https://en.wikipedia.org/wiki/Rockwell_XFV-12

I'm definitely in ...two ideas are bouncing around and both are total wiffs but one is OTB 
This GB is gonna be fun and kinda easy and hard at the same time 😆
There's so many RW builds which were bad ideas just to start there alone ..then we have to think up more bad ideas..easy 😅
Both of my builds will be tracked ..come to think of it I could make it 4 for this ..all tracked ..all bad ideas and 3 would be OTB   

The russian round monitor Novgorod, maybe ?

An extremely bad idea from a navel prospective 😆
Perfect

I wonder if the Stipa-Caproni was the first ducted fan (or at least ducted prop) aircraft ever?

Motorjet engines!
a rudimentary type of jet engine.
At the heart the motorjet is an ordinary piston engine (hence, the term motor), but instead of (or sometimes, as well as) driving a propeller, it drives a compressor. The compressed air is channeled into a combustion chamber, where fuel is injected and ignited. The high temperatures generated by the combustion cause the gases in the chamber to expand and escape at high velocity from the exhaust, creating a thermal reactive force that provides useful thrust.

I think Caproni Campini N.1 was the first aircraft to use it (what is it about all the weird Italian aircraft?)
The Soviets built some prototype aircraft.

It'd be even more a bad idea if it was steam powered......................

ground launching a proper Orion craft ( the 40M + version)  from close to a populated area     Flash, Boom, up,  Flash, BOOM, up 

one of the ones mentioned in some of the books on TSR2  in that they couldant get a single powerful nuke so had to try Stick Bombing with multiples

Our esteemed colleague raises an interesting subject for discussion  here.  Is there something psychoactive in the water near the Caproni works, or have the design team been smoking that funny "herbal tobacco"  again?............and is it infectious, as it seems to have been passed on to Piaggio (Pc7) and Savoia Marchetti  (SM92)

What about the ducted fan Spitfire (see https://www.secretprojects.co.uk/threads/supermarine-spitfire-mk-ii-with-ducted-fan.34103/) or the radiator-shaped ramjet thingies designed for Spitfires that Colin Freightdog produced in 1/72 (see https://www.whatifmodellers.com/index.php?topic=29960.0)
