Excellent shots, lovel the Facel Vega comp too, but I have to say the Rolls Royce with Gurney Nutting Body would be perfect for a nice day out an a picnic

Yes you have.......
four pictures above it
Contra-rotating propellers have been found to be between 6% and 16% more efficient than normal propellers.[1] However they can be very noisy, with increases in noise in the axial (forward and aft) direction of up to 30 dB, and tangentially 10 dB.[1] Most of this extra noise can be found in the higher frequencies. These substantial noise problems will limit commercial applications unless solutions can be found. One possibility is to enclose the contra-rotating propellers in a shroud. It is also helpful if the two propellers have a different number of blades (e.g. four blades on the forward propeller and five on the aft).[citation needed]
The efficiency of a contra-rotating prop is somewhat offset by its mechanical complexity. Nonetheless, coaxial contra-rotating propellers and rotors are moderately common in military aircraft.

Thanks Pete. If I'd stayed at the barrier next to where the Spits were parked they would have been a lot better but we went for a wander after they took off and everytime they came close after that, they were either either behind the other 'parked' planes or between me & the sun. Good flying display tho
Anyhoo, how did the drive go with yer new Dutch mate? Nice lad, eh.
I saw him talking to the red Mk1 Cortina's owner for ages too so maybe he got to have a spin in that too

Also contra rotating props won't torque roll you off the side of the boat if you open the tap too quick.
Nice pics, I think I'm going to move down south, although times look hard for some of the Rolly guys, tesco sandwiches instead of a hamper from Fortnums

The old boy with the RR that had the Tesco salad on his fold-down table was from 'oop north' going by his accent, when we spoke to him.
So yes he prob would have had a Fortnum & Mason's hamper instead if he were a local
