How to up grade a JLF-TP-8YT?

This is a video on upgrading a JLF-TP-8YT at [media=youtube]QytcbzZmXaI[/media]. However, I want to increase the deflection time to very high. Do anyone know how???

When you say deflection time, what exactly are you trying to get across? Do you want to have the joystick perform looser, returning to neutral position slower? If that is the case then you will want to switch to a weaker spring, or modify your JLF spring by cutting and stretching it. I hope this addresses your problem.

i you want it looser you may want to use a ls-33 spring, but only the ls-33 spring.
