A lot of work thought and work went into that but no way it would cool with that setup. A lot of things to prove flight worthy here...
WW2 warbirds had problems with it. Some had to limit the initial takeoff power until they had enough airspeed to control the roll.I don't think torque is a big problem. We have RC models with enough thrust to hover vertically. The pilot hardly notices torque with a tiny bit of aileron.
They probably need a bunch of right rudder, but I doubt it's worth going contra-rotation. One Reno racer had contra-rotation, I don't remember if it was worth it. The short blades and hub drag on that look terrible to me.Some had to limit the initial takeoff power until they had enough airspeed to control the roll.
Rivets would be cool, but if you update to be the fastest, it would morph into the fastest looking ones today.
There have been 3. Red Baron, Precious Metal and Miss Ashley II.One Reno racer had contra-rotation
Take a look at the Italian Macchi-Castoldi M.C. 72 which set a world's speed record of 440 Mph in 1934 - a record that still stands today for piston-engined seaplanes. Contra-rotating props solved the problem of excessive torque.
The Macchi has always impressed me. What a tremendous accomplishment in the mid '30s!Take a look at the Italian Macchi-Castoldi M.C. 72 which set a world's speed record of 440 Mph in 1934 - a record that still stands today for piston-engined seaplanes.

Pedalling has taken man at 144 km/h ( 89 mph ) and solar power high nearly 300 km/h....and put them together and you get 144+300= 444.

Your arithmetic is not correct. You can't add it like that. Drag is proportional to the square of the speed.
How did you manage to get soooo far off topic on your own thread???I agree you cannot....or you can, but it does not hold water.
Pedalling would bring around 2-5% more power to a light system and solar power 10% of the needed energy to fly efficiently.....or rather practically.
You still need the 85% from the batteries ( or other system ).
If you fly solar and pedal power alone you are restricted to speeds of 30-50 km/h ( faster at high 80-100 km/h even ).
