Taxying downwind in strong winds in the Chippy you can feel if it needs up or down elevator. If the elevator wants to go to either the upper or lower stop due the tailwind, it means the tailwind is stronger than the prop wash, so stick forward to give 'down' elevator so the tailwind blowing on it holds the tail down.
If the elevator wants to trail neutrally, prop wash is stronger than tail wind, so bring the stick back to give up elevator so the prop wash will pin the tail down.
Of course as power setting varies during taxy, you may have to change from one to the other.
One has to be aware on the chippy, taxying downwind in strong winds, not to let the tailwind blow the rudder hard over. That will apply full wheel brake on one wheel which can raise the tail when you're not expecting it. Guess how I know!
