Yes, the engines spool up when the gear is extended in most cases. There are a number of factors that can play a part, for example, environmental changes or whether the plane is in take-off or landing.
"Spool up the engines" refers to the process of increasing the speed of an aircraft's engines from idle to operational power. This involves allowing the engine components, such as the turbines and compressors, to accelerate and reach the necessary RPMs for takeoff or optimal performance. It is a critical step in preparing the aircraft for flight, ensuring that the engines are functioning properly and ready for the demands of takeoff.
a spoolcase is something that you use in sewing or when you sew you put the spool into a spoolcase but you must make sure the spool is filled up with thread then you can start sewing only if you have a long piece of thread in the spool!!
The thread moves from the spool through the needle to make stitches on a sewing machine. The thread take-up lever is what feeds the thread from the spool to the needle as it moves up and down.
1. Rotate spool to line up arrows on spool and surrounding casing. 2. Find notch and pry with wide flat-end screwdriver. 3. Spool will pop out.
It is easy to increase the speed of engines - but the question is why would you want to - most of the engines are way over speed as comes from the factory - all you have to do is change the drive gears (check with Walther's for the gear's in your scale).
It depends on the length and quality. Regular curling ribbon on a small spool is about $5, but 50-yards can get up to about $20.
To load the Ryobi trimmer head, first remove the spool cover and line up the arrows on the spool with the eyelets on the trimmer head. Insert the line into the eyelets and wind it in the direction indicated on the spool. Make sure the line is secure and replace the spool cover.
Take the spool off the the machine. By that I mean the part that contains the cutting line. There will be a spring that drives the spool. Get a pair of pliers and gently pull on it. If it comes out of the shaft it is probably broken or it came loose. If that does not solve the problem look at the spool where the nut is located make sure its there and that the housing is not wallowed out. If so buy a new spool.
That would be retractable landing gear. They're present on aircraft because retracting the landing gear makes the aircraft more aerodynamic by eliminating the drag which would be caused by having the gear permanently fixed or extended. This saves fuel and improves cruising speeds.
When plane wheels are retracted during flight, it is referred to as "gear up" or "landing gear retraction." This action is part of the takeoff procedure, allowing for improved aerodynamics and reduced drag. The landing gear is typically retracted shortly after takeoff and extended again when preparing for landing.
