Flight SIM Levers are tight
All levers should fit with gentle pressure applied. If you find the levers are too tight you can easily adjust them by applying heat.
The easiest method is to soak the socket end in hot water for 10 seconds (adjust accordingly). Shake off any excess water and fit to the quadrant, slide the lever up and down as the plastic cools.
If the levers are to lose you can apply pressure to the outer walls. - water temperature circa 65°C (149°F)
A layer of Sellotape wrapped around the top of the quadrant lever or blue-tac also is useful to ensure a tight fit.
Never glue the levers direct to the quadrant, you will want to change them in the future!
