"The vertical cylinder under the dash is the oleo pneumatic accumulator mechanism of the landing gear when it came Charlestop. It was unreliable and was replaced in 1934 by Messier system"
"Charlestop imagined a position indicator signal by train .... on the floor:
two color squares, two by half train, were placed on the panels near the finish line
The square had 1 m square and coding was:
- White / white: train down
- Red / red: train identified
- Green / green: the two half train half out
- White / Red: half being dropped on the green side, and raised red side - and vice versa"
"The diagram shown in NACA Report 765.
The cylinder can not be displayed more clearly with its function.
If it is a part of the train Charleston, I ask myself: this cylinder he was removed with the installation of the train Messier?
On the other forum, Fasm just posted a scan that contains another photo of the cockpit that I would like to put here:
Handles are seen on both sides, and the center cylinder. The review date of June 1935, but the picture may be older and it is not known if the plane had Charlestop Messier or train."
"the presence of the cylinder indicates that the Charlestop train was in place, so a photo taken before 1934.
In an aircraft, any excess weight is banned because consumer power. This is especially true for a racing plane.
The replacement train Charlestop by Messier had had to lead the full removal of items Charlestop.
A bottle of 8l steel tested to 70 bar weighed about 5kg. Here the cylinder also included a piston, a sealed chamber, and pressure was 100 bar.
On the model 450, you represent the fixed gear, it should not be the battery or the bottle right (Edit: unless it is the fire extinguisher).
C460: The gear actuators Charlestop were hastily replaced by struts (The messier trains will be installed later)"
